A lithium battery equalizer is a device designed to balance the voltage and state of charge
Lithium ion batteries are becoming increasingly popular and require a different equalization voltage than lead acid or nickel-cadmium batteries. Battery equalization voltages for lithium ion battery packs should be between 1.8 and 3
The battery equalizer balancer works in a high-frequency pulse way bi-directional energy transfer system, high efficiency, low loss, time for battery maintenance, online maintenance and activate cells, battery voltage imbalance, once detected by way of energy transfer to discharge the battery or charging operation, make the battery in every single battery cell dynamic flow, To achieve
When cells have uneven voltages, it can lead to overcharging, undercharging, and reduced battery life. Equalizers prevent these imbalances by transferring charge from high voltage cells to low voltage cells, maintaining an optimal voltage level throughout the pack. There are two primary types of lithium battery equalizers: active and passive.
the second way to choose a battery equalizer depends on the number of batteries you have and the voltage of the battery packs. Usually, there are 12V, 24V, 48V, 60V, 72V, 96V, 192V equalizers available on the market for certain battery configuration. The 12V equalizer is produced by Victron energy.
Battery equalization voltages for lithium ion battery packs should be between 1.8 and 3 volts per cell in order to maintain performance. There are several equalizers on the market for different battery types, they are: Vicron battery balancer, HA Series Lithium ion Balancer and HWB series Lead ACid Battery Balancer:
Based on cell-to-pack-to-cell topology, the equalizer consists of a switch array and a single-ended forward bidirectional DC-DC converter, which is simple, efficient and reliable. During discharging process, energy flows from the most charged cell to the battery pack, realizing peak-cut equalization.
The experimental results show that the designed equalizer can quickly realize battery equalization with little energy loss. This equalizer can improve the consistency of batteries, and prevent over-charge and over-discharge of a battery pack, which has good application value for the BMS in EVs.
Conclusion Based on cell-to-pack-to-cell topology, a novel active equalizer for Li-ion battery has been designed, including a switch array and a single-ended forward bidirectional converter. The experimental results show that the designed equalizer can quickly realize battery equalization with little energy loss.
