Detailed Description:

Features：

3 temperature sensorsper 15 strings, 12 total for 60 strings; 15 total for 75 strings.
SOC estimation error ≤ 5%.
3 relay dry contact output.
PC software will be provided for customers to debug BMS and modify system parameters.
Support 7 BMS in parallel.
HMI display: Optional (3.5-inch screen)
Each 15 strings is a battery collection unit, and 75 series batteries have 5 acquisition units.
BMS integrated machine components are composed of BMS main control board, BMU sampling board, high voltage board, switching power supply, Hall sensor, DC contactor, micro switch, power terminal, structural box and wiring harness, etc.; the characteristic is that the maincontrol board Integrate with sampling board and other power devices to keep the system as a secondary architecture.
It has the characteristics of compact structure, flexible installation and low cost, and is suitable for integrated installation with small capacity batteries.
The BMS integrated machine component is mainly suitable for the charge and discharge management of lithium iron phosphate batteries (LFP). If you need to modify the parameters with other batteries, please contact our company for confirmation.
