Battery BMS worked as a electronic parts . it may suffere some problems in many circumstances ,the mostly reasons belongs to incorrect connection or installation for some new makers without sufficiently battery assembly experience . wrong connection with battery can easily damage the BMS circuit and therefore caused some problems for the normal working of your vehicle or electrical equipments . we shared some common problems hereby in according to our experience with our friends so that we can avoid some problems in advance :

Common problems analysis

1. Why does the Battery system can not be charged after connection with BMS ?

2. Why does the Battery system can not be discharged  ?

3. why there are no charge protection ?

4. why there is no over-discharge protection with your BMS  ?

5. why does the power turn off once starting the motor ?

6. Why does the power cut-off occur during driving process ?

7. Why does the power cut-off when accelerating the speed ?

8. Why does the voltage drop down after full charge ?( the discharge mosfet does not turn on or takes reference to Number 2 case)

9. why does the Vehicle can not run longer than our expected distance ?

10. Why does BMS getting over-heated in process of discharge ?

11.  Why does BMS get hot in process of charge ?

12. Battery was be charged to swelling status ?

13. why does the Battery drained completely to 0 Volt ?

14. Why does the battery charge fast and discharge also fast ?

15.  Battery can not be charged and discharged after long term rest ?

16. Why  does your vehicle can run longer in winter than in summer ?

17.  Smart BMS common problems and some solutions for the problems .
