Battery equalization voltage refers specifically to the specific voltage that must be applied to many batteries in order not to overcharge or undercharge them, while equalizing charge ensures batteries of all types receive an even amount of charge.
We therefore propose two effective on-line equalization algorithms aiming at maximum pack capacity for lithium-ion battery packs based on charging cell voltage curves (CCVCs). The first part of the series briefly reviews equalization topologies and algorithms.
Equalizing charge is the charging protocol used by many battery companies to ensure batteries are equalized and charged in a uniform manner.
The equalization strategy is embedded in a real BMS for practical application analysis. Lithium-ion battery pack capacity directly determines the driving range and dynamic ability of electric vehicles (EVs). However, inconsistency issues occur and decrease the pack capacity due to internal and external reasons.
We subsequently propose on-line equalization algorithms for lithium-ion battery packs based on charging cell voltage curves (CCVCs). The objective of these algorithms is to maximize pack capacities by conditioning CCVCs. As the first paper of the series, we first briefly review equalization topologies and algorithms.
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 volts per cell in order to maintain performance.
