Charged EVs | Eaton launches new battery disconnect unit for EVs


Eaton has launched a brand new battery disconnect unit (BDU) for EVs that acts as an on/off change to the battery for various EV working modes reminiscent of charging and driving.

The BDU will be linked to Eaton’s Breaktor circuit safety know-how, which gives present switching and resettable bidirectional short-circuit safety. The corporate says, “Eaton’s Breaktor circuit safety know-how allows as much as 350 kW DC quick charging when used to guard and change the DC fast-charge circuit, permitting EVs to cost in quarter-hour or much less.”

“Our Breaktor circuit safety know-how’s self-triggering design, diagnostic electronics and mirror contact assist obtain BDU purposeful security targets,” mentioned World Product Technique Supervisor for Eaton’s eMobility enterprise Kevin Calzada. “With its built-in coil driver, economizer, and the sensing/triggering circuit, Breaktor circuit safety know-how additionally reduces battery administration system price and complexity.”

Based on Eaton, “Present EVs depend on considered one of three conventional BDU configurations: fuse and contactor; pyro fuse and contactor; or fuse, pyro fuse and contactor all used collectively in a single BDU.” The corporate says a BDU linked with Breaktor tech reduces the necessity for as much as 15 elements, together with pyro and thermal fuses in addition to contactors.

“Our BDU mixed with our Breaktor circuit safety know-how gives the whole lot wanted, in a compact and environment friendly bundle, to guard the automobile and occupants,” mentioned Calzada.
