The rising development of the EV market has created vital challenges to battery producers on how they take a look at and validate the performance of battery modules and packs successfully and effectively, particularly throughout excessive voltage checks. It’s also vital whereas manufacturing to stick to related take a look at requirements and laws through the take a look at phases.
The 4 major take a look at phases with related take a look at functionalities and programs:
- Sub-Module Welding Check: High quality verification on welding for the battery sub-modules
- Module-level Finish-of-Line (EOL) Check: Useful verification for the person battery modules below a scientific take a look at
- Automated Check System (ATS) for module-level In-Line (IL) Check: Useful verification for the all battery modules below a scientific take a look at earlier than putting in the exterior enclosure
- Automated Check System (ATS) for pack-level Finish-of-Line (EOL) Check: Useful verification for manufacturing battery pack previous to the discharge to the car assemble
These take a look at phases and programs proven above have created a number of technical and logistic challenges. Primarily based on the years of expertise in aiding the OEM clients all over the world in testing battery modules and packs, Chroma ATE discusses intimately the highest 5 challenges of automated pack degree end-of-line battery testing.
