20Ah 400V 8kwh ESS Wall Mounted Lithium Battery High Voltage

400V high voltage ESS wall mounted lithium battery 8kwh

1. Features of 400V high voltage wall mounted battery

• Using EV-grade Lifepo4 battery cells that ensures the best consistency
• Providing uninterrupted power to users. Can satisfy the requirement of users under the extreme environment, such like the power failure caused by earthquake and flood
• Saving electricity for users by peak-shift. Under the price of peak valley, if the power consumption is big in the rash hour, this system can help to save expenditure by storing electricity during the electricity troughs, and using in the peak time.
• Service life of more than 4000 cycles
• Can be connected in parallel to get more power

2. System control of High voltage 400v wall mounted battery
2.1 Battery management system requirements
2.1.1 Battery management system function
(1) Single battery voltage detection;
Using special voltage measuring chip, including high precision A/D conversion module.Accurately and timely monitor the
status and changes of the battery during use.Effective to prevent improper use of the battery.
(2) Battery temperature detection;
NTC temperature detection scheme, with fault detection ability of broken wire and short circuit.
(3) Balanced management;
BMS can trigger passive equalization under certain conditions according to the capacity of individual cells in the battery
system.
(4) Battery working current detection;
A 300A hall sensor current acquisition scheme is adopted.
(5) Insulation resistance detection;
The standards and recommendations are shown in the following table:
The fault level Insulation resistance advice
0 >500Ω/V normal
1 Between 100Ω/V and 500Ω/V Timely maintenance
(6) Estimation of battery SOC;
The hall sensor is used to sample the current, complete current measurement and SOC estimation, and conduct fault
classification alarm for high and low SOC according to the control parameters provided by the battery manufacturer.
(7) Battery failure analysis and online alarm;
BMS has the self-diagnosis function of the system. After the system is powered on, it will test the voltage, temperature,
communication, clock, storage, internal communication and other components. Meanwhile, it will judge and alarm the
battery failures such as over voltage, under voltage, over current, over temperature, SOC too low/high and consistency
according to the information provided by party a.
(8) Monitor communications;
BMS USES high-speed CAN communication to report the battery status timely and reliably, effectively preventing battery
abuse.
