1. Application This Battery Management System(BMS) is designed to monitor 8-16 cells in series battery pack. It has multiple functions, including single cell over voltage and under voltage protection, pack over voltage and under voltage protection, charging and discharging over current protection, high and low temperature protection, short circuit protection and protection recovery. what’s more, it can also calculate the SOC status precisely and keep voltage balancing during charging and discharging, and collect the SOH statistics. All monitoring parameter settings and data can be configurable through the communication between RS485 and the master via CAN BUS and communicating with software on PCs. (Master controller baud rate 9600.)

2. Electric Features 2.1 cell and pack voltage monitoring The BMS measure the voltage difference in real-time. And provide over voltage and under voltage warnings once the the the cell voltages are out of safe operating voltage range. At room temperature of 0-45 ℃ , the measured voltage difference is about ±10mV. However, at the temperature of -20～0℃ and 45～70℃, the measured voltage difference is up to ±30mV. 2.2 Temperature of individual cell, environment Temperature and power temperature monitoring 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℃. 2.3 Charging and discharging current monitoring The BMS calculate the in or out loading current by monitoring the impedance in the charging and discharging circuit. And providing over current or short circuit warnings and protections. If the operating temperature is lower than 40 ℃ , the measured current count is within 1% difference. 2.4 Short-circuit Protection Function

The BMS monitors the output circuit and provides short circuit protection. 2.5 Capacity and cycle life The BMS estimate the remaining capacity of the battery pack after the primary full charge and discharge. The capacity count is within in 5% difference. And for the cycle life, it can calculate the cycle life according to your setting DOD percentage. 2.6 Charging and discharging MOSFET power switch monitoring The MOSFET power switch, featuring low internal resistance, big current, is an optimization design for the capacitive load starting, switch free, fast charging and high voltage of back up battery bank. 2.7 Individual cell equalization Settings of charging and standby can be configurable to prolong the battery pack cycle life. 2.8 LED indicator 6 LED lights indicate the battery remaining capacity, operating mode and warning status. 2.9 Power switch The power switch is used to power on/off the battery manually. 2.10 CAN and RS485 communication interface The data monitoring, battery pack control and parameter settings can be remote controlled through software on PCs or mobile devices. 2.11 Battery management parameter settings All the parameter settings, including individual cell over voltage, battery pack over voltage, over current during charging and discharging, high temperature of battery cell and operating environment, equalizing strategy, battery pack in series, battery capacity etc., can be reset through battery studio software. 2.12 Battery management function settings All voltage, temperature, current and capacity related functions can be turned on/off manually with host-application battery studio software. 2.13 Soft start and charging current limitation 2

Start time can be set from 1ms-1000ms to apply to different capacitive load. Limited charge current can be turned on or off. Turn on the limited charge current function can prevent parallel circulation and impact from the charger. 2.14 Parallel Communication The address can be set through RS485 concatenation and 8 dial addresses. The terminal device can read the battery data of the PACK parallel machine through the CAN interface. 2.15 historical data record Historical data is stored according to the state transition of the BMS; real-time storage of measurement data when various alarms, protection triggers and eliminations; realizing the storage of measurement data within a certain period of time by setting the recording start time, recording end time and recording interval . Currently, it can store up to 300 historical data records, which can be read by the host computer and saved as an excel file to the computer.
