Cell Balancing in Electric Vehicle Battery Pack Passive and Active cell balancing techniques. Electric vehicles, as well as associated technologies, will be extremely important. One such example is battery technology.
Maintaining a battery pack’s full capacity is an important component of running an EV properly because failure to do so can lead to serious safety and logistics issues. Many li-ion cells are connected in series and parallel to form battery packs, which have a total battery voltage and output power.
Voltage imbalances in these cells can result in overcharging or undercharging. Temperature variations can lead to variations in the initial charge capacities and cell voltages. This prevents the cell’s capacity from being used to its full potential, which leads to poor battery performance, shortened battery life, and a possible fire risk.
Cell voltage balancing, which ensures that all of the cells are uniformly charged and discharged by employing one of the aforementioned methods of cell balancing, is one such technique that can be utilized to eliminate these imbalances. Initial passive balancing Balancing that is active.
They simulate both approaches and perform a detailed analysis. Cell Model Battery Model: To form a complete battery pack with a certain rating of power, voltage, and current, several cells with different nominal voltages and capacities are arranged in series and parallel.
Depicts one such cell model with a 7.2V cell voltage and 0.00475Ah capacity. This cell discharges from 100% to 0% without the aid of any balancing circuits in about 2500 seconds.
Grid to vehicle and vehicle to grid This system is bidirectional, allowing power to flow in both directions. Through an inverter, the battery can send electricity back to the grid, and a rectifier, the grid can send energy to the battery.
The operation of the supply grid can be enhanced by using V2G technology, and there won’t be a large demand for EV loads from the supply and distribution grids, avoiding the cost of replacing the current grid infrastructure.
The inverter circuit that can convert DC to AC power and the output. The rectifier circuit that can convert AC to DC power and the output . The SPWM control that was used to generate gate pulses for the switches and the output.
Balance of active cells The idea of a strong and weak cell is the same in this way as it was in the passive cell balancing method, but the technique is improved. Here, the circuit makes an effort to exert better control over the cell voltages and extracts all of the cells’ available capacity for utilization.
Various components, such as inductors or capacitors, can be used to transfer the extra energy from a stronger cell into a weaker cell with less energy.
The pack will contain both strong and weak cells, and there is a good probability that the stronger cells will be overcharged and the weaker cells will be over discharged.
In this method, a resistor with a switch is connected across the cells, where the extra energy from the stronger cells is squandered in the resistor if the stronger cells generate greater potential than the weaker cells. The transistor switch allows for fast control over the resistor’s operation at the appropriate time.
The electric vehicle It was thought that voltage and energy imbalances in battery packs were degrading the pack’s overall performance. Using the passive balancing and active balancing cell balancing strategies, this problem was resolved.
This increased the battery’s total capacity by ensuring that the cells in the battery pack did not overcharge and by maintaining an even voltage across all of them. The results were acquired in a graphical format after the balancing circuits were developed and simulated in MATLAB.
A comparison was made, and it was discovered that the active balancing strategy, which is more effective at managing energy between the cells, was a superior method of accounting for the imbalances in the cells than the passive balancing methodology.
