Li-Ion Battery Management for EV

Since the foundation, we focused on lithium ion battery, so jointly developed power supply device and charging related for EV with an automobile company.

The control board(BMS) was a revolutionary one the time.
Currently, this lithium ion control technology is utilized in the our ESS products.

Electric Assisted Bicycle Battery Charger

In addition, that technology was used to charge batteries for electric assisted bicycles.
Besides, we developed a non-contact charging system for communication terminal.
Our charging technology brought abundant examples.
