EV battery module balancer launched to identify defective units

LinkedIn +

A new electric and hybrid battery module balancer has been launched by ATEQ SAS, to equalize voltage differences between modules to maximize battery performance.

EV vehicle assembly plants cannot just assume the batteries they put in their electric vehicles are perfect. If batteries are underperforming, it is likely due to electric cell imbalance. Slight differences in the module capacity, temperature, state of charge, self-discharge rate and impedance can lead to a deviation in voltage.

When an EV battery is diagnosed as being defective, the faulty module needs to be replaced. The EVB5100 Module Balancer charges or discharges the new replacement module to the same state of charge as the other modules.  Performing the battery balancing onsite with the EVB5100 saves time and money since the transportation of batteries and modules is complex and expensive.

The EVB5100’s color screen guides the technician to select the right battery module type from the database, set the target voltage, and charge or discharge the module safely thanks to the protective lid and advanced security features. The EVB5100 delivers a detailed report that can be transferred to the factory network, or accessed remotely via a cloud-based interface.

ATEQ also offers leak testers used at every step of EV battery production, from leak testing the insulation of each individual battery cell pouch, to testing the battery module. With the addition of the EVB 5100 to the current leak, flow and battery testing product line-up, ATEQ now provides solutions for the production process, for final QC assembly, testing and maintenance.
