Energy storage system function introduction :

1.Balance function , prevent the battery cells voltage unbalance ,lengthen the battery pack lifespan .

2. singel battery cell voltage detection,and provide exact over charge and discharge data to protect voltage

3. battery module multipoint temperature data conllection ,provide the same quantity temperature data conllection as voltage ,stricly monitor battery temperature is unformity to lengthen the battery pack life span .

4. estimate each battery pack distribute SOC ,support the each battery pack power controll ,increase the battery system module available capacity and lifespan .

5.high precision current detection to provide the basically for SOC estimation ,protect the battery from the over charge current

6.three layer module structure can meet with differenece voltage and capacity battery pack demand

7.the system inner data transmission use the CAN 2.0 high speed BUS interface.

8.provide many kinds of communication connector to connect internet ,include RS485,CAN,RS232 .

BMS functions:

the first protection:

1.battery cells over charge and discharge alarm

2.battery cell over temperature alarm.

3. instantaneous high temperature alarm

4.over teperature difference alarm

Application :

Energy storage station ,home energy storage ,Emergency power supply ,Smart microgrid , power grid frequency regulation ,distributed energy sources system
