Problems solved by technology
[0004] The purpose of the present invention is to provide an efficient battery energy overall balance method in order to solve the above problems. It solves the problem that when charging batteries connected in series at present, the charging efficiency is different due to the different performance of the batteries. Some batteries are fully charged, and some batteries are not Reach, lead to overcharge of the single battery on the battery pack, loss of resistance, and overheating of the battery, which is not conducive to energy saving and charging protection of the battery

The invention discloses an efficient battery energy overall balancing method. The battery energy overall balance comprises a battery pack and a balance system; the battery pack is formed by connectinga plurality of single batteries in series through a circuit; the balance system is composed of a plurality of balance units; each balance unit corresponds to each single battery one to one, and the balance units are used for balancing the voltage of the single batteries and battery series-connection overall voltage; each balance unit comprises a voltage detection module, an intelligent control module and a boosting module; each voltage detection module is used for detecting the voltage of each single battery on the series batteries; the output end of the voltage detection module is electrically connected with the input end of the intelligent control module; the output end of the intelligent control module is electrically connected with the boosting module; and the boosting module is usedfor boosting the voltage of the single battery detected by the voltage detection module in an overcharge state to the overall voltage of the battery series connection. The method has the beneficial effects of no resistance loss, no overheating of the batteries, energy saving and charging protection.
Description
Technical field: [0001] The invention belongs to the technical field of battery capacity balance, and in particular relates to an efficient overall battery energy balance method. Background technique: [0002] The battery components are connected in series and in parallel. The parallel battery pack requires the same voltage of each battery, and the output voltage is equal to the voltage of one battery. The parallel battery pack can provide a stronger current. There are no excessive requirements for the series battery pack, as long as the battery The capacity is about the same. A battery pack in series can provide a higher voltage. Battery packs are widely used in our daily life. TV remote controls, electronic toys, and flashlights all have series-connected battery packs. In battery packs, there are always differences between monomers. Taking capacity as an example, the difference The resistance will never tend to disappear, but gradually deteriorate. The same current flows...
