Method for overcoming poor equilibrium of batteries

Abstract

The invention discloses a method for overcoming the poor equilibrium of batteries. The method comprises the steps of 1, enabling a standby single lithium battery to be connected with a lithium battery pack; 2, enabling leads to be respectively connected with all single lithium batteries; 3, enabling switching tubes to be connected with the leads connected between all the single lithium batteries and standby single lithium batteries; 4, enabling all the switching tubes to be connected with a controller; 5, enabling another standby single lithium battery to be connected with the lithium battery pack, and repeating the actions of the steps 2, 3 and 4 until the installation of all the standby batteries is completed. When the electric quantity of one single lithium battery is about to be used up, the corresponding standby single lithium battery is connected with the lithium battery pack by the corresponding switching tube, and the single lithium battery, the electric quantity of which is about to be used up, is short circuited. The method does not adopt a way of charging while use, so that the power consumption caused by using the high capacity lithium battery to charge a low capacity lithium battery is saved, and the generation of heat is reduced. The method for overcoming the poor equilibrium of the batteries can solve the problem of difficulty in realizing the equilibrium of the lithium batteries, and does not gather a great deal of heat in the batteries, thus not threatening the safety of the batteries and not seriously reducing the service life of the lithium battery pack.

Description

technical field [0001] The invention relates to a method for overcoming battery dispersion, especially a method for overcoming poor battery balance. Background technique [0002] Lithium battery is currently the best product for storing electrical energy. Lithium battery is light in weight, high in capacity, and can provide high power, which makes lithium battery widely used in various electric industries. The voltage of a lithium battery cell is generally 2.8 volts to 3.2 volts. When a higher voltage is required, multiple lithium battery cells need to be connected in series to increase the output voltage; The battery cells are connected in parallel to increase the output current. [0003] However, the dispersion of lithium batteries is very strong, that is to say, the performance indicators of different lithium battery cells are very different. When the power of one lithium battery cell is exhausted, the other lithium battery cell still has sufficient power. [0004] The ...
