Our need to preserve the environment has compelled us to look for sustainable alternatives that won’t damage it. One such solution that runs emission-free is the use of electric vehicles. These vehicles run on rechargeable battery packs, which consist of several cell modules arranged in parallel and series. The electricity produced by these battery packs is several hundred volts.
They are necessary for a number of internal vehicle functions. Because of this, it is crucial to manage and observe the batter. This can only be done by the use of an embedded system called the Battery Management System (BMS), which keeps an eye on the parts that are closer to the battery cell. Each battery cell needs to be closely monitored to ensure that there are no voltage fluctuations or malfunctions.
If you’re in the market to buy the best e-rickshaw loader in India, first understand the main features of the battery management system. In this blog, we have outlined the major functionality of BMS and how it works.
What is a Battery Management System(BMS)?
A key component in guaranteeing the safety of electric vehicles is a Battery Management System (BMS), which controls the electronics of a rechargeable battery, whether a cell or a battery pack. By guaranteeing that the cell operates within its safe operating parameters, it protects both the user and the battery. The Battery Management System (BMS) keeps track of the battery’s State of Health (SOH), gathers data, regulates external elements that impact the cell, and balances them to maintain uniform voltage throughout the cell.
The Major Functionalities Of BMS
As mentioned above, the functionality of BMS is not only increasing the security of electric vehicles, but it also prevents several malfunctions. Given below are the subsequent task of BMS:
Controlling the heat
The primary factor influencing a battery is its temperature. The thermal management system of the battery monitors and regulates its temperature. These systems can be either active or passive, with air, a non-corrosive liquid, or a phase change as the cooling medium. However, one of the easiest ways to regulate battery temperature is to use air as a coolant.
Using the energy produced by regenerative braking, the BMS can also be used to recharge the battery. This energy is obtained when excess kinetic energy is converted back into chemical energy or another form. The battery is recharged using this energy as well. The energy is transferred to the battery pack by the BMS.
The State of Charge (SOC), which represents the battery’s charge level, is quantified by the EV Battery Management System. Battery performance optimisation is aided by BMS. When a cell is discharging, the BMS communicates with the motor controller to keep the voltage too low.
Enhancement of Performance
Optimising the battery pack’s performance is the responsibility of the BMS. When the State of Charge (SoC) of lithium-ion batteries is kept between the minimum and maximum charge line specifications specified in the battery profile, the batteries function at their best. Deep discharging and overcharging both reduce the battery’s capacity and shorten its lifespan. The BMS calculates the maximum amount of current that can be safely added during charging.
The Bottom Line
Undoubtedly, the battery management system is one of the essential parts of electric vehicles that guarantees dependable and safe vehicle operations.
