BTMS-140 Battery Thermal Management System

The development and design of each component of the unit have been refined to ensure the product’s capacity and efficiency.

The control mode is divided into BMS control mode and automatic control mode.
● BMS control mode
The battery thermal management system fully obeys the instructions of the BMS, including working mode, cooling or heating power and the setting of antifreeze target temperature, which are controlled by the BMS by transmitting communication information.
●Automatic control mode.
The battery thermal management system according to the maximum and minimum temperatures, charging status and discharge status of the battery sent by the BMS. Automatically evaluating the operating mode, cooling or heating power and target temperature setting of the antifreeze.
