System management functions:
Cell and battery pack overvoltage, low voltage alarm and overvoltage, undervoltage protection. The voltage detection accuracy of the cell is ±10mV from 0°C to 45°C, ±20mV from -20°C to 0°C, and ±20mV from 45°C to 70°C.
Overcurrent alarm and protection of battery pack charge and discharge current, and battery pack output short circuit protection. The continuous charge and discharge current is 100A, the temperature rise is less than 50℃, and the current detection accuracy is better than 2%.
Real-time calculation of the remaining battery capacity, complete the learning of the total capacity of charging and discharging at one time, and the capacity estimation accuracy is better than 5%. Can automatically configure and record charging and discharging 2 Reignwood Xinde New Energy Co., Ltd. 3 cycles.
High temperature and low temperature alarms, high temperature and low temperature protection of battery cells, environment and power MOS. 6-channel temperature monitoring, including 4-channel cell temperature sensor, 1-channel ambient temperature sensor, 1-channel power MOS thermometer sensor, temperature detection accuracy is ±3℃.
Low internal resistance, high current, optimized design for large capacitive load startup, zero switching, and high charging withstand voltage for backup power applications.
The charge equalization strategy can be set flexibly, which can effectively improve the battery life and cycle life.
6 LEDs indicate remaining battery capacity, working mode and alarm protection status.
Intelligent one-key switch design, the system can be manually turned on when it is off, and can be manually turned off when it is not in the standby power state. Long press the button to reset the BMS by software or hardware and clear various abnormal states.
PC or intelligent front-end can realize battery data monitoring, operation control and parameter setting through commands such as telemetry, remote signaling, remote adjustment, and remote control. Realize the monitoring and management of battery cascade through RS485, and support RS232 communication and Modbus protocol at the same time.
The discharge MOS, charging MOS, current limiting function switch, buzzer alarm switch, forced sleep switch, etc. can be turned on and off through the host computer.
10A and 20A current limiting modules are optional, the host computer can set charging current limiting, or charging is not limited.
Various battery management parameters such as single battery overvoltage and undervoltage, total battery voltage overvoltage, charging overcurrent, discharging overcurrent, cell high and low temperature, environmental high and low temperature, equalization strategy, number of battery cells in series, and battery capacity can be passed through The upper computer is used to reset the settings.
The BMS design is equipped with a unique hardware watchdog protection circuit. Ensure that the BMS can operate safely and reliably for a long time in harsher environments.
The BMS system can be set to enable the system to perform real-time storage of operating data. For system monitoring, analysis and maintenance.
BMS system can realize online upgrade of system software through serial port.
It has the function of measuring the tilt angle of the gyroscope. When the product is moved and tilted at an angle (30°), the BMS controls the shutdown of the discharge MOS and prohibits the discharge, thereby realizing the anti-theft function.
When a short circuit occurs at the load end, the BMS has a short circuit protection function, which can quickly turn off the discharge MOS, cut off the loop, and activate the short circuit protection function. Recovery conditions for short-circuit protection: charging or manual recovery.
The BMS is equipped with a 4G/GPS function interface to expand the peripherals, and is equipped with a 4G/GPS module, which can remotely view the status of the BMS, realize real-time positioning of the BMS, and achieve the purpose of anti-theft.
The BMS has a display function interface and is equipped with a display module, which can view various data and status of the display.
With an anti-reverse connection circuit, when the positive and negative polarities of the external power supply are reversed to the positive and negative polarities of the BMS, the BMS will not be damaged and will alarm and enter the cut-off protection state. Recovery conditions for reverse connection protection: remove the power supply (back pressure) and release it immediately.
BMS has anti-surge function, which can suppress the surge impact of 4KV.
BMS is equipped with a dissolver function interface and is equipped with a dissolver module, which can trigger the fire signal according to the feedback signal of the dissolver, and achieve the function of early warning and fire prevention.
