6 Frequently Asked Questions about “Lithium battery pack automatic balancing”
How does a battery balancing system work?
The BMS compares the voltage differences between cells to a predefined threshold voltage, if the voltage difference exceeds the predetermined threshold, it initiates cell balancing, cells with lower voltage within the battery pack are charged using energy from cells with higher voltage (Diao et al., 2018).
Why is SoC balancing important in EV battery pack?
After performing cell balancing, each cell's SoC reaches 60 % (average SoC) which signifies that all cells have reached to same level or balanced. Therefore, SoC balancing is crucial in EV battery pack to increase the usable capacity. Fig. 3. Charge among five cells connected in series before and after SoC balancing.
What is a prototype battery balancing system?
The prototype is built for 4 series-connected Li-ion battery cells, a BMS with voltage and current sensors for each cell, and dedicated cell balancing circuitry. The pack current and cell voltage are measured using a current sensor (TMCS1108B) and a voltage sensor (INA117P).
