6 Frequently Asked Questions about “New energy battery charging equalization method”
Does battery equalization reduce power performance?
Charge imbalance reduces the power performance and available energy of battery packs. Hence, it is necessary to perform battery equalization. This article proposes an active equalization circuit and a novel equalization strategy to achieve energy redistribution.
How to equalize the charge of a battery?
Charge equalization among batteries can be executed by controlling the battery currents in accordance with the real-time estimated state-of-charges (SOCs) by the coulomb counting method. By accounting for battery capacity degradation, the SOCs can be estimated more precisely by identifying the maximum releasable charges of the batteries.
What is battery equalization technology?
Abstract: Battery equalization technology is a key technique in the research of electrochemical energy storage system. It balances the state of charge (SOC) of cells in series-connected battery packs using the power electronic converters to improve the life of battery packs significantly.
Is a battery equalization circuit necessary for energy redistribution?
Hence, it is necessary to perform battery equalization. This article proposes an active equalization circuit and a novel equalization strategy to achieve energy redistribution. A bidirectional equalization topology consisting of a forward transformer and switch matrix is proposed first.
What is an equalization charge?
An equalization charge is a battery charge at a slightly higher voltage than normal. On a 12-volt battery system, this may be 15.5 volts to 16.2 volts. With normal use, starting batteries do not require any equalization throughout their service life. In some household or deep-cycle applications, an equalization charge may be necessary.
Does the equalization strategy improve the inconsistency of battery packs?
Both the simulation and experimental results validate that the proposed equalization strategy not only improves the inconsistency but also increases the equalization speed. In practical battery pack experiments, the pack capacity is improved by 16.84% after equalization, and the equalization time is decreased by 23.8% using the proposed method.
