Electrifying industrial autos is a crucial a part of lowering emissions, so it’s irritating that the tempo of fleet electrification has been so gradual. Viable industrial EVs have been round for years, however fleet operators insisted on conducting years-long pilots to show their reliability. Now that section is over, and corporations are beginning to place substantial orders, however they’re working into one other hurdle—charging infrastructure must be constructed out, and managing it’s a advanced affair.
California-based WattEV is constructing a community of charging hubs designed for electrical vehicles, incorporating photo voltaic technology, battery storage and energetic vitality administration. These megawatt charging websites will probably be open to all fleet operators. Nonetheless, the corporate additionally has a extra bold technique—by 2030, it hopes to have a gigawatt of charging capability put in to assist 12,000 of its personal vehicles, a part of a Truck-as-a-Service enterprise mannequin that it’s going to supply to fleet operators.
The primary piece of the puzzle, which is now below building, is the Bakersfield Electrical Truck Cease, a 110-acre, 40-megawatt, solar-powered, electric-only public truck cease. Strategically positioned between the Central Valley and the Los Angeles megalopolis, the charging hub will characteristic a photo voltaic microgrid with battery storage, plus grid vitality from PG&E.
Charged spoke with Salim Youssefzadeh, WattEV’s CEO, in regards to the firm’s imaginative and prescient of a worthwhile zero-emission transport fleet.
Charged: You’ve damaged floor in your first facility. Is all of it designed and deliberate out? Have you ever chosen the distributors for the charging stations and the opposite {hardware}?
Salim: Yeah. We’ve began building, and are wanting ahead to having the positioning operational by the tip of 2022.
On the photo voltaic area, we had been initially taking a look at single-axis monitoring, however as we dug into it, we noticed that it turns into very pricey. We began taking a look at different designs, and got here throughout an Australian firm known as 5B that has a containerized resolution all pre-wired. The panels are fastened, however they’re on east-west inclinations. It is available in a container, and pulls out like an accordion, and also you even have the next density of photo voltaic panels in a smaller space. So, we’re in a position to get to 40 megawatts, and our annual vitality manufacturing is equal to [what it would be if we used] single-axis monitoring, however our price is considerably decrease.
On the battery storage aspect, we plan to make use of [energy storage provider] Stem’s resolution, with Tesla Megapacks with about 4.5 megawatt-hours of capability. Long run, as our vehicles undergo their helpful life cycles, we plan to exhibit their viability as second-life battery storage in future phases.
For the EV chargers, we’re going to be utilizing CCS dispensers from [power supply manufacturer] Phihong initially. However we evaluated the entire producers that produce EVSE, and we shortly realized that loads of them don’t have the true dynamic charging functionality that we’re in search of. And plenty of of them are removed from having MCS [the Megawatt Charging System, a new high-power standard for charging heavy-duty EVs]. So despite the fact that we’re putting in Phihong chargers for among the preliminary cost dispensers as much as 360 kilowatts, we’re additionally, in parallel, designing our personal true dynamic charging tools.
For our Bakersfield facility, we’re going with 16 MCS connectors and 64 240 kW CCS connectors, so there’ll be 4 of our containerized options moving into there.
Charged: You’re going to develop your personal proprietary charging station?
Salim: Right. We’ve already submitted patents, and are about to start out designing it and constructing out prototypes. The one which we’re designing can have 4 MCS connectors and 16 CCS connectors in a single containerized unit of 4 megawatts. Due to its distinctive switching functionality, it may possibly dynamically allocate energy to every of these dispensers as wanted, and relying on the dimensions of the venture, you may add quite a lot of containers. For our Bakersfield facility, we’re going with 16 MCS connectors and 64 240 kW CCS connectors, so there’ll be 4 of our containerized options moving into there.
Charged: So, relying on what sort of truck pulls in, some can cost with CCS and a few can use MCS.
Salim: Right. The thought can be that the CCS ones would permit for in a single day charging and the MCS can be for fast alternative charging. We hope to put in it towards the tip of 2023.
Charged: I perceive that the bodily format of truck charging websites is essential. I’m guessing that you simply consulted with some trucking trade consultants about find out how to design the parking, the charging stalls, and so on.
Salim: Completely. Yeah, it was a mixture of going to truckers, and we had despatched this over to Volvo and Daimler to touch upon. However we’re additionally wanting on the routing of the cabling, as a result of that additionally turns into pretty pricey, so this was designed contemplating the trucker’s routes as they go out and in of the charging areas, in addition to find out how to optimize for the shortest cable runs.
Charged: Wanting on the preliminary rendering, I don’t see any restaurant, retailer or restrooms.
Salim: That’s an awesome level, and the concept is so as to add these at a later stage. We needed to maintain the primary stage pretty easy in order that we are able to get it up and working as quickly as attainable. As we develop our web site and undergo the remaining phases, we are going to construct out eating places, however we’re additionally wanting into meals vehicles for that first section.
Charged: Inform us about your Truck-as-a-Service enterprise mannequin.
Salim: We began WattEV with the intent of changing into the principle supplier of public charging for electrical vehicles, however we shortly realized that it wasn’t sufficient for us to simply construct the infrastructure and anticipate the demand to choose up naturally. That’s after we actually began wanting into the vehicles, the capabilities that they’ve and the course that they’re moving into. The vehicles that we’ve got ordered for supply in This autumn 2022 have a two-to-three-hour cost time and a 250-mile vary. That is removed from the vary that almost all diesel vehicles supply, and a two-to-three-hour cost time is unacceptable to most drivers. In an effort to overcome these constraints, we got here up with a “Pony Categorical” mannequin the place a truck may be picked up at one depot and swapped at one other for a totally charged truck. That is perfect within the middle-mile sector, since most routes fall inside the vary of the car, and we are able to strategically place our autos at our depots to permit for a charged truck to be accessible when wanted.
Figuring out the routes for the Pony Categorical mannequin is an interim drawback we have to clear up as a way to maximize utilization of the belongings and get the Whole Price of Possession (TCO) at par with diesel. As soon as vehicles with MCS charging grow to be accessible, this turns into much less of a difficulty for the reason that cost time is drastically diminished to about half-hour.
By the tip of 2022, we can have our websites in Bakersfield, Gardena and San Bernardino operational, together with 50 Volvo VNR Electrical vehicles. These three websites fall right into a 180-mile radius from one another, and are on main trucking corridors that are perfect for working our TaaS mannequin. When a driver [drives] the route, they’ll simply drop off the truck, choose up a fully-charged truck and proceed on their route.
Charged: So it’s like again within the previous stagecoach days, once they would alternate drained horses for contemporary ones at each cease?
Salim: Right.
Charged: What vehicles do you might have on order?
Salim: We’ve 50 phase-two Volvo vehicles on order, [which are] anticipated to be delivered on the finish of 2022. We’ve additionally reserved 50 Tesla Semis, which we hope to get someday in 2024. We all know that out of the gate, Tesla can have MCS functionality, whereas the Volvos will probably be utilizing CCS. We plan to restrict the variety of CCS vehicles we’ve got on order for primarily getting operational, and to push the market in the direction of MCS with all of the OEMs.
Charged: So, Tesla goes to have MCS functionality on the Semi.
Salim:That’s what they’re promoting. They’re an energetic member in CharIN [the organization responsible for standardization and development of MCS]. They had been, for probably the most half, main the event of the connector sort. And I imagine Tesla has put in a megawatt dispenser at their Nevada Gigafactory, which is presently getting used for testing with one of many vehicles.
Charged: So, you’ve received the photo voltaic, you’ve received the storage, you’ve received the EVSE. You have to have some kind of a software program package deal that’s coordinating all that.
Salim: Completely. There is a pretty big quantity of effort that goes into the vitality administration system and [calculating] find out how to greatest optimize between utility, photo voltaic and battery, in order that we’re all the time utilizing probably the most cost-effective and greenest supply of vitality. Our whole system is packaged with California-based vitality administration specialist Stem. They’ve an entire resolution that they’re engaged on that’s ready to absorb all these inputs and provide you with an output utilizing probably the most cost-effective resolution.
With our product that we’re creating, the MCS and CCS mixture, it really works with a posh switching matrix the place we’ve got a 4 MW energy supply, and the system can change between the completely different dispensers. As an example, we’ve got 16 CCS dispensers and 4 MCS dispensers all tied to this one field, and that field will be capable of change and dynamically allocate the facility to every of these dispensers as wanted. This might all be software-controlled, and use the identical customary protocols which are presently used for the charging tools and the autos. We even have loads of effort going in the direction of growth of the TaaS platform that manages all the things from truck ebook to routes and charging.
Charged: You’re going to have your personal vehicles below your TaaS mannequin, however is that this charging hub additionally going to be accessible to different fleets?
Salim: Completely. All of our stations are going to be publicly accessible.
Charged: So far as different fleets’ vehicles coming in and paying to cost, I feel lots of people anticipate that to be a reasonably low-margin enterprise. Would you say that your TaaS mannequin is a technique to make the numbers work out higher?
Salim: Yeah, completely. The Truck-as-a-Service mannequin is an all-inclusive package deal that features the car, the charging, and upkeep, all at a worth that’s on par with diesel. And since we’re in a position to basically management our personal vitality supply and the way the belongings are optimized, we are able to assure the bottom worth attainable and enhance the utilization of our personal fleet.
The Truck-as-a-Service mannequin is an all-inclusive package deal that features the car, the charging, and upkeep, all at a worth that’s on par with diesel.
The transportation trade is predominantly operated by contractors or owner-operators with one to 5 vehicles of their fleets. And even with all of the mandates and initiatives going in the direction of zero-emission transport, there’s fairly a couple of obstacles which are stopping owner-operators from stepping into zero-emission transport. The worth of a few of these electrical Class 8 vehicles is sort of 3 times that of a brand new diesel. And also you couple that with unknown vary, insurance coverage and upkeep, and there’s loads of the explanation why these drivers aren’t going to the dealerships and shopping for these vehicles immediately. Our resolution is meant to assist take away loads of these obstacles, and make it extra accessible and inexpensive to anyone that desires to get into zero-emission operations.
Charged: So, your buyer base may embody the truck drivers themselves, the owner-operators?
Salim: Sure. And we’re already in discussions with loads of shippers which have sustainability objectives. We pitch them on what we’re doing and present that they’ll meet their sustainability objectives with no out-of-pocket capital from themselves. That permits us to get contracts for these hundreds after which we are able to offtake these to completely different drivers.
Charged: The ports of Los Angeles and Lengthy Seashore are within the information rather a lot lately. Are you actively working with them as a company?
Salim: Completely. One in every of our upcoming websites that we’re discussing is a facility that’s very near the port. And our Gardena location as effectively is inside 5 or ten miles from the port itself. We’re in energetic discussions with them on the initiatives that they’ve. As an example, [the ports are planning to impose] a charge of $10 per TEU [20-foot equivalent unit] for anyone that’s not working inexperienced. When a driver goes into the port to choose up a car, they’d be paying an extra $10 TEU charge in the event that they’re not working with a zero-emission truck. However we really launched a white paper on a distinct resolution that we had in thoughts that incentivizes operators to drive utilizing zero emissions, so it seems to be at it from an alternate perspective the place fairly than penalizing them, we reward them for utilizing zero-emission autos.
Charged: We’re believers in battery-electric vehicles, and I think you’re too. However we hear loads of discuss hydrogen, and loads of elected officers sound fairly eager on it. What would you say to anyone that claims hydrogen is a greater resolution?
Salim: That’s an awesome query. We initially began taking a look at hydrogen, and we had been taking a look at creating inexperienced hydrogen by way of the usage of electrolysis, which is much more pricey than the standard means of [generating] hydrogen, which is utilizing SMR, steam methane reforming. We really went down the highway of seeing what it could price to construct a photo voltaic area, after which energy an electrolyzer utilizing photo voltaic to create inexperienced hydrogen. We began wanting into the price of the tools and the storage and transportation, and what we shortly realized is that, as a way to transport inexperienced hydrogen, you need to liquefy it and get it right down to very chilly temperatures, which turns into very pricey. And the vitality density that you’ve got remains to be nowhere close to as efficient as that of going on to a battery. A variety of your loss is definitely by way of warmth dissipation. So, to people who are taking a look at hydrogen as a supply, it’s been mentioned that it’s [been] the gas of the longer term for the previous 20 years. It most likely will proceed to be so.
However on the preliminary stage, zero emissions utilizing battery-electric is unquestionably the way in which to go, as a result of you may get on the highway proper now utilizing [existing] autos, and thru the usage of your community and the way you place your infrastructure, you may enhance the vary of these battery-electric autos rather more successfully than in the event you had been to make use of hydrogen and construct out stations in every single place.
Charged: The engineering or scientific case for battery-electric appears so apparent. Why do politicians appear so receptive to pitches for hydrogen?
Salim: I feel they’re wanting into it as a result of they don’t need there to simply be one winner, proper? If you happen to have a look at the complete ecosystem, having competitors in numerous options is unquestionably the way in which to go to guage completely different applied sciences. And I’m positive finally there will probably be hydrogen vehicles which have lengthy vary, nevertheless it’ll take fairly a while.
And in the event you have a look at a few of these OEMs which are moving into that course, they’re saying that hydrogen is efficient as a result of you may cut back the burden and you may basically enhance the cost time, so you may gas up sooner than with a battery-electric truck. However with the way in which know-how’s going with MCS, you’re rising the battery density, so you may retailer extra vitality in that very same weight of battery. After which with the cost time, you may deliver it right down to 30 to 45 minutes, which is near diesel. However by way of the complete ecosystem, I feel it’s wholesome to have many alternative applied sciences and options within the works at any given time.
Charged: So far as the vehicles, you’re shopping for Tesla and Volvo and perhaps Daimler. Are there another OEMs on the market that you simply see as promising?
Salim: Positive. We’ve checked out all of them, however our long-term [goal] is to push the complete market in the direction of MCS. The preliminary fleet that we ordered from Volvo is utilizing CCS, however the concept is that, as soon as we get supply of these and put these into operation and actually debug our software program and infrastructure, then we push them in the direction of growth of MCS-capable autos.

Charged:What are the largest technical challenges to vary over from CCS to MCS?
Salim: I feel the largest issue for them is having sufficient of a market demand to try this. Proper now, basically battery chemistry wants to vary to what MCS requires. A variety of the OEMs don’t really manufacture their very own packs, they purchase them from third events, so they should guarantee that the voltage necessities meet the specs of MCS, in addition to the battery density and the spacing between the cells. Then on high of that, you need to design for the cooling facets, the connector is completely different, and the battery administration system could also be completely different. All of those modifications contribute to price. For these OEMs to make that change, they should have a large enough demand from a big participant to actually begin moving into that course and placing in their very own CapEx to transform to MCS.
Charged: So, the long-term plan is to make use of your first three charging hubs as fashions for tons extra throughout the nation?
Salim: Sure. We’re very excited in getting these three websites operational and making zero-emission transport accessible and inexpensive to loads of owner-operators that want to get into this. And for the shippers, we’re permitting them to satisfy their sustainability objectives a lot sooner than in the event that they had been to do it on their very own with their very own CapEx.
These three websites are the primary of many who will probably be coming on-line inside the subsequent few years. Our imaginative and prescient is effectively past California to go nationwide as effectively. With Bakersfield we’re testing loads of completely different applied sciences to actually present that we are able to deliver down the price of the infrastructure considerably by way of photo voltaic and battery storage, in addition to our personal charging design. If we are able to exhibit that there, then we are able to simply duplicate it anyplace else.
