BMS is short for battery management system
1), battery cell voltage detection: Detect 0~12 piece(can be setted)cell voltage detection of the battery in series, cell voltage sampling range 0~4.5V, sampling precision± (0.3%RD+0.2%FS).
Total current: Current sampling range: -1000A~1000A, sampling precision± 1% not below national standard. Static state show 0, when sampling current is less than 0.5% full scale of Hall sensor, directly set up as 0, prevent zero-drift effection.
2), environment temperature:
Each collection module has 3temperature measuring transducer todetect environmental temperature, temperature sampling range -40° C~ 80° C, sampling precision ± 0.1° C.
3), battery equilibrium:
In use, choose active equilibrium, receive the Equilibrium command send by cotroller, can charge some relative battery cell, max equalizing current is 5A, close the equilibrium when not receive controller equilibrium command for more than 10s.

4), heat management driving interface:
Dry point output, can receive Heating device start temperature and stop temperature send by control modules, and Control heating management start and Stop according actual detect temperature, default is 15° When start, 25° Stop.
5), air fan management interface:
24V power supply output. Can receive air fan device start temperature and stop temperature send by control modules, and Control air fan management start and Stop according actual detect temperature, default is 45° Cwhen start, 30° C stop.
6), Communication interface: Offer CAN bus interface, uploading above 1 part and 2 partand 3 part collection information, and receive the control information of control module through CAN interface.
7), polling period: Cell detection period and module polling period not more than 10ms.
