Balance charging is completed, while the electrochemical performance of each single electric core is improved in a consistent manner, thereby enabling the consistency of the battery pack to be better.
Description
Technical field
The present invention relates to a kind of high-frequency impulse formula power battery pack equalizing charger, belong to battery charger field.
Background technology
Conventional group charger generally adopts charger to carry out serial connection charge to battery pack at present, because battery pack is composed in series by many monomer battery cores, between each monomer battery core, inevitably there is individual difference, and although the mode of serial connection charge is easy, fast, but the carrying out along with charging, wherein must there be indivedual monomer battery cores to arrive maximum charging voltage, and other monomer battery cores also do not reach this voltage, if continue as batteries charging, must cause some monomer battery core to overcharge, when if total voltage reaches specified charging voltage, wherein some monomer battery core does not also reach maximum charging voltage, this is that charger has just stopped work, must cause indivedual monomer battery core charge less electricity, therefore, indivedual monomer battery cores in battery pack are overcharged or charge less electricity for a long time, cause monomer battery core seriously to produce a polarization, thereby affect the performance and used life of battery pack.
Recently, people progressively pay attention to the equalizing charge research of battery pack, the method of some equalizing charges has been proposed successively, yet the method proposing is at present all to propose on the basis based on constant-current supply or constant voltage source, yet the difference due to the electrochemical behavior of each metal ion species in different electrolytes, power supply wave mode is also different on the impact of various electrochemical reaction processes, at present conventional DC charging pattern is not best on the impact of electrochemical reaction process, pass through practice summary, the present invention proposes a kind of high-frequency impulse formula power battery pack equalizing charger.
