Technology Solutions for EV Battery Management System
A Battery Management System manages the health of the battery pack installed in electric vehicles. It acts as a safeguard against various issues that can cause the battery to malfunction. The Central Control Unit (CCU) and Local Control Unit (LCU) in the BMS framework help improve system performance, safety, and cell management.
The primary task of Battery Management Systems is to ensure the optimal use of the residual energy present in a battery.
The system continually checks the cells and battery pack in order to increase system efficiency and safety, for a variety of metrics. These parameters include
- Over-Temperature
- Under/Over Voltage
- Under/Over Current
- Charge (Capacity)
- Power Consumption
- Remaining Running Time
- Charging Cycle
- Battery Health
To improve the overall health of the battery system and cells, active/passive cell balancing functionality is built into the BMS architecture.

Our Expertise
Key Highlights Under Battery Protection
In the event of battery malfunctions like overcharging, undercharging, short circuits, overheating, etc., safety mechanisms must be deployed to keep the EV and its occupants safe and cool. For this, Embitel provides a variety algorithm as part of BMS solution that extend the battery's lifespan and efficiency under stress.
Voltage and Current Protection
Voltage and Current Protection
In order to detect Over-Voltage and Under-Voltage, BMS actively monitors the voltage of each cell and the battery pack. The battery pack is protected from overcharging and over discharge via overcurrent monitoring.
Temperature Monitoring
Temperature Monitoring
Each cell’s temperature is monitored in order to maintain excellent performance and efficiency while protecting the battery pack from overheating.
Cell Monitoring / Balancing
Cell Monitoring / Balancing
To avoid an imbalance in the charge levels of the individual cells that make up a battery, it is ensured that they are operated within their safe operating range. It monitors and responds to the State of Health (SoH), State of Charge (SoC), and Depth of Discharge (DoD).
Diagnostics and Relay Control
Diagnostics and Relay Control
Relay control and diagnostics employ multiple-point voltage monitoring, fault monitoring, and continuous parameter monitoring to guarantee safe operation and dependable battery performance. Through the orderly execution of relay activities, the pre-charge function is integrated.
Optimized Charging and Discharging
Optimized Charging and Discharging
High efficiency and cutting-edge features are offered by switch-mode power supplies (SMPS) for quicker and cooler charging
Isolated CAN Communication
Isolated CAN Communication
To improve efficiency and save costs, daisy chain communication between LCUs is used in the communication, which is CAN-based. Galvanically isolated CAN circuits provide dependable communication.
Security
Security
Authentication ICs offer reliable protection against duplicate goods. The usage of only approved accessories is validated. By doing this, user devices are less likely to sustain harm from duplicated inferior accessories or parts.
High Voltage Interlock (HVIL)
High Voltage Interlock (HVIL)
The HVIL function in electric vehicles detects aberrant high-voltage component disconnections and protects the system.
Isolation Measurement
Isolation Measurement
Guarantees safety by keeping an eye on excessive voltage leaking into the vehicle’s body. Leakage resistance is monitored while the car is running and in ON mode.
