Description

Introductions :

This Integrated BMS was built with  main control board, BMU sampling board, high voltage board, switching power supply, Hall sensor, DC contactor, microswitch, power terminal, structural box and wiring harness, etc.; the characteristic is that the main control 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 parameters setting in according to your battery.

• Each 15 strings is a battery collection unit, and 75 series batteries have 5 acquisition units.
• 15 probes for every 15 strings, for a total of 15
• current collection uses Hall sensor, safe and reliable, no heat;
• SOC estimation error ≤ 5%;
• 3-digit address dialing to set the BMS address;
• 3-channel relay dry contact output;
• 4-channel contactor expansion and auxiliary contact detection;
• Support for parallel use (maximum 7 units)；

Works Operation :

Startup process

Make the BMS in the shutdown state and complete the connection with the BMS. After the BMS is assembled, turn the micro disconnect switch on the chassis to “on”, then press the start button (DC start), and the BMS will enter the self-test.If the self-test is normal, you can hear the sound of the contactor closing, the green light on the chassis is on for a long time (it will flash if there is external communication), and the start is completed.

Shutdown/transport status

After the system starts and starts normally, turn the micro disconnect switch to “off” to turn the BMS into shutdown / transport status. If the BMS is not usedfor a long time, the BMS must be in this state.

Working State:

Transaction terms :
1) Shipment time : once received your order ,we will proceed it quickly within 3~4 working days without problems .order can be cancled within these days ,otherwise we will reject to cancle the order ,because our items can not get back when in the process of shipment . we will inform our buyer if  there is a stock problems with the order and arrange a properly agreenment on the shipment schedule by email .
