This is a lithium-ion battery protection circuit developed by the Osaka-produced EV development project.
The "Control Circuit for Li-ion Batteries (BMS)" is a protection circuit necessary for monitoring the voltage of each cell during the use of lithium-ion batteries. Supported by the Osaka Industrial EV Development Grant, the development project for this product started in 2010 and it has various features. It can be displayed on a liquid crystal monitor, allows for changes to the setting conditions, calculates SOC, and includes correction factors, among many other diverse features. If you are interested, please feel free to consult with us. 【Features】 ■ Dedicated to lithium-ion batteries ■ Developed through the Osaka Industrial EV Development Project ■ Upper and lower limit voltages can be set arbitrarily in increments of 0.01V ■ Capable of discharging at 1A ■ Degradation diagnosis is performed through DC resistance measurement *For more details, please refer to the catalog or feel free to contact us.
