The key function of a lithium battery BMS is cell balancing. What is a conventional BMS and how is the Flash Balancing System different?
In those fancy BMS, lithium battery balancing can even be set to occur or not occur depending on the voltage level of the cell groups. In contrast, the most basic, low-cost BMS will always balance the cells regardless of the state of other factors such as cell voltage, discharge or charge state, etc.
There are many reasons the cells in a lithium-ion battery need to be balanced. If a cell group is lower than the others, the BMS will put the battery into safe mode long before the energy in the rest of the cells is used. If a cell group is too high, charging will be cut off before the other cell groups are full.
The concept of cell balancing in battery management systems (BMS) ensures that the energy distribution among the cells is balanced, allowing a greater percentage of the battery’s energy to be recovered. This is especially important for long battery strings that are used in scenarios that frequently require recycling.
A study conducted at the University of Shanghai for Science and Technology compared the performance of passive and active cell balancing techniques for Lithium-Ion Batteries. The bleed resistor-based passive cell balancing took more than 16000 seconds to reach a 0.01V difference for capacitors with 5F capacitance.
Furthermore, the BMS manages the charger during battery charging and applies dependable battery equalization techniques based on the information supplied for each cell. This is done to ensure that each cell's SoC remains as uniform as feasible during the charging and discharging cycles (Ruiz et al., 2018).
The role of the BMS balancing current is to equalize the State of Charge (SoC) of individual cells within a battery pack. By achieving this balance, all cells reach the same SoC during the charging and discharging cycles. ...
