Functions

BTMS: battery thermal management system

is a very cricital unit in an electric bus, it's duty to provide a most comfortable temperature climate for grumpy battery unit.
Battery units work well at a temperature range of 10-30 degree centigrade, but in cold and hot weather, battery performance declines, and battery cells either become volatile or too dull. CLING BTMS acts like a nanny to babysit thoese sensitive batteries. It works under the command of BMS, battery management system to output capacity to cool or heat the coolant carrier. A bad BTMS has the potential to lose control of battery climate and thus cause a fire, that's too bad.

Features:

1.PTC heater for liquid (6-14 kw)

can be equipped, working mode include:

standby, cooling, heating, auto circulation.

2. Web control can be realized

3. CAN2.0 communication

4. Self diagnose function

5. Real time info upload

6. EMC meets grade III requirement

Application:
