The main function of Remarks

　　A battery voltage detection : For 10 amp battery using principal differential detection from transportation, to ensure accuracy , precision voltage detection voltage detection control system within ± 15mV.

　　Temperature detection : with a negative temperature coefficient NTC temperature sensor detects the temperature , the temperature detection range -20 ℃ to 80 ℃, can be a point or two-point temperature , temperature detection accuracy of ± 2 ℃

　　3 Current detection : current detection precisely calibrated accuracy up to ± 300mA.

　　4 power measurement : electricity metering points can be used to measure voltage and current measurements . Optional

　　5 communication ports : Connect to the PC host computer for data monitoring, acquisition and calibration procedures . Only for testing

　　6.LED instructions : BMS optional LED indicates battery voltage , battery charge and discharge , and failure status . Optional

　　7 system self-test :. BMS system set up self-test function , the system power voltage , temperature, communications and other components for testing to ensure that the system itself is working properly.

　　8 System Monitoring :. BMS for the battery pack voltage, current and temperature monitoring , the effective protection of the battery pack when a failure occurs .

　　9 discharge activation : BMS activation charge a load or , in the case do not take the load and the charger , BMS in the off state , BMS at this time is almost zero power state, then load or charger when BMS activated automatically enter the working state . BMS after activation , if the load within one hour or the charger is not connected , BMS automatically enters power-down state .

　　10.BMS with internal discharge absorb the counter electromotive force protection .

　　11 charge-discharge circuit: can be charged and discharged the same port , or charging , discharging port separation.
