BMS, I-VEC, Battery Management System

Product Overview:

A Battery Management System (BMS) performs key functions to manage and optimize the performance of complex battery:
1. Monitoring: BMS continuously monitors the battery's voltage, current, temperature, and state of charge to ensure that it is functioning within safe and optimal parameters.
2. Balancing: BMS balances the cells within the battery pack to ensure that they are charged and discharged evenly, preventing overcharging or over discharging of any single cell.
3. Protection: BMS provides protection against safety hazards such as short circuits, thermal runaway, and overcurrents by disconnecting the battery from the load when necessary.
4. Optimization: BMS optimizes the battery's performance by controlling its charging and discharge cycles to maintain a consistent level of power and extend its operational life.
5. Communication: BMS communicates important information such as battery status, charging status, and fault codes to the user or host device, allowing for better battery management and maintenance.

How does a BMS protect the battery?

A Battery Management System (BMS) protects a rechargeable battery in several ways:
1. Overcharge protection: BMS monitors the battery's voltage and disconnects the battery from the charging source when it reaches a predetermined maximum voltage to prevent overcharging.
2. Over Discharge protection: BMS monitors the battery's voltage and disconnects the battery from the load when it reaches a predetermined minimum voltage to prevent over discharging, which can damage the battery.
3. Short-circuit protection: BMS monitors the battery's current and disconnects the battery from the load in case of a short circuit, which can cause a dangerous increase in current flow.
4. Thermal protection: BMS monitors the battery's temperature and disconnects the battery from the load if it exceeds a safe temperature threshold, which can cause thermal runaway and damage the battery.
5. Overcurrent protection: BMS monitors the battery's current and disconnects the battery from the load if it exceeds a safe current threshold, which can cause damage to the battery or even pose a safety hazard.

How does a BMS calculate the state of charge (SOC) of a battery?

A BMS calculates the SOC of a battery by measuring the voltage and current of the battery and using an algorithm to estimate the amount of energy remaining in the battery. The accuracy of the SOC calculation can be affected by factors such as temperature, battery age, and manufacturing variability.

How does a BMS handle cell balancing?

Cell balancing is the process of equalizing the voltage of individual cells in a battery pack. A BMS can handle cell balancing by controlling the charging and discharging of individual cells to bring their voltages into balance.

How does a BMS communicate with other vehicle peripherals?

Our BMS supports various communication interfaces such as CAN and RS485. There is also an optional of BLE for communication. BMS can send information such as the battery's state of charge, voltage, current, and temperature to other systems, and can also receive control signals from other systems to regulate the charging and discharging process.
