采购商询盘内容
I'm currently working on a battery pack project and need some assistance with a BMS that appears to have some connection issues. I've set up a 4S lithium iron phosphate battery with a BMS where I've connected the B0, B1, B2, B3, and B8 terminals to the main positive. The B+ terminal is also linked to the main positive. However, there's no continuity between the B- and P- terminals, and the indicator light isn't lighting up.
When I measure the voltages, I'm getting 13.19V between B- and B+, and 11.87V between P- and B+. Despite having connected NTC-A and NTC-B properly, the lack of a connection between B- and P- is concerning. Could you help troubleshoot this issue? Any guidance would be greatly appreciated.
我目前正在做一个电池组项目，遇到一个电池管理系统（BMS）连接问题，需要一些帮助。我连接了一个4S磷酸铁锂电池和一个BMS，并将B0、B1、B2、B3和B8端子连接到了主正极。B+端子也连接到了主正极。但是，B-和P-端子之间没有导通，指示灯也不亮。
我测量电压时，B- 和 B+ 之间为 13.19V，P- 和 B+ 之间为 11.87V。尽管 NTC-A 和 NTC-B 已正确连接，但 B- 和 P- 之间没有连接，这令人担忧。您能帮忙排查一下这个问题吗？非常感谢您的指导。
