Battery Management System (BMS) Diagnostics & Repairs in London
Expert solutions for hybrid and electric vehicle BMS problems
What is the BMS in a Hybrid or EV?
The Battery Management System (BMS) is the brain of your hybrid or electric vehicle’s battery. It monitors and manages:
- 🔋 Voltage, current, and state of charge (SoC)
- 🔋 Battery state of health (SoH) and degradation
- 🔋 Temperature monitoring and thermal safety
- 🔋 Cell balancing for performance and longevity
- 🔋 Communication with other vehicle modules (e.g., inverter, ECU)
If the BMS fails, your EV or hybrid may stop charging, shut down, or enter limp mode.
Common BMS Faults
- ⚠️ Faulty cell balancing leading to reduced battery performance
- ⚠️ Incorrect state of charge (SoC) readings
- ⚠️ Thermal management errors due to faulty sensors
- ⚠️ Communication breakdown with inverter or ECU
- ⚠️ Failure to allow charging or sudden cut-off
Warning Signs of BMS Issues
- 🚨 “Check Hybrid System” or “EV System Service Required” messages
- 🚨 Vehicle won’t charge or charges inconsistently
- 🚨 Sudden loss of power or limp mode activation
- 🚨 Dashboard warning lights related to battery or electrical system
- 🚨 Rapid drop in driving range
