Products Description
1. Battery voltage detection
Real-time acquisition and monitoring of the voltage of the series cell to realize the alarm and protection of overvoltage and undervoltage.The voltage detection accuracy of the cell is ±10mV at 0 ~ 45℃ and ±30mV at -20 ~ 70℃.
Alarm, protection parameter setting can be changed by the upper computer.
2.Cell, environment and power temperature detection
The BMS measure the cell temperature, ambient temperature and power temperature in real-time via NTC to provide high temperature or low temperature warnings and protections.
The measured temperature difference is within ±2℃ Cell temperature sensor USES 10K, B value 3435.
Alarm, protection parameter setting can be changed by the upper computer.
3.Battery charge/discharge current detection
The charge and discharge current of the battery pack is collected and monitored in real time by detecting the resistance of the current connected in the charge and discharge main circuit, The current accuracy is better than ±1%.
Alarm, protection parameter setting can be changed by the upper computer.
4.Short circuit protection function
Has the function of detecting and protecting the output short circuit.
5.Battery capacity and cycle times
Real-time calculation of battery residual capacity, complete the learning of total charging and discharging capacity at one time, SOC estimation accuracy is better than ±5%.
It has the function of counting the number of charge and discharge cycles. When the accumulative discharge capacity of the battery pack reaches 80% of the set full capacity, the number of cycles will increase once.
Alarm, protection parameter setting can be changed by the upper computer.
6.Charge, Discharge MOSFET switch
Low internal resistance, high current, high capacitance for backup power applications load startup, zero switching, double charging voltage optimization design.
7.Balance of intelligent single cell
Unbalanced cells can be balanced when charging or standby, which can effectively improve the service time and cycle life of the battery.
Equalizing open voltage and equalizing differential pressure can be set by upper computer.
8.LED indication function
There are 6 LED indicators, 4 white LED indicators for the current battery SOC, 1 red LED indicator for alarm and protection failure, and 1 white LED indicator for battery standby, charging and discharging state.
9.Dormant function
BMS has manual and automatic sleep functions; Automatic sleep function: The battery will automatically sleep for 48 hours when there is no external charging or discharging. When the battery pack is over-discharged, the communication is maintained for 1 minute, and the BMS enters the dormant state.
Manual sleep function:
1. By manually pressing the 6S reset button, the BMS enters sleep after the 6 LED lights light up in sequence.
2. The switch is controlled by an external switch, the switch is turned on when the switch is closed, and the switch is turned off when the switch is off.
The standby and hibernation can be set through the host computer.
10.One-key switch machine
BMS in parallel, the host can control the slave machine and boot. The host must dial the code according to the parallel mode, the host dial code address can not achieve one-click switch machine. (The batteries return to each other during the machine and can not be shut down by one button)
11.CAN ,RM485 and RS485 communication interfaces
CAN communication according to each inverter protocol to do communication, can connect inverter communication.(Note: Compatibled with Pylon, Goodwe, Deye, Luxpower, TBB;and can be switched to Growatt, Victron, SMA, SOFAR, Ginlong, and Studer)
RM485 communication according to each inverter protocol to do communication, can connect inverter communication.(Note: Compatibled with Pylon,Growatt,SRNE )
PC machine or intelligent front end can realize the data monitoring, operation control and parameter setting of the battery by RS485 communication telemetry, remote signal, remote adjustment, remote control and other commands.
12.Communications
Can be set through RS485, through 8 dial address address setting.
Two ways to view data:
1.Connect the upper computer through RS485 set
2.After the RS485 set is connected, the host CAN/RM485 interface is connected to the inverter
