Abstract
The utility model relates to a simple equalizing circuit for a 5-section serial rechargeable battery pack. The simple equalizing circuit takes energy from the 5-section serial rechargeable battery pack, and selectively charges a certain monomer rechargeable battery in the serial rechargeable battery pack through an isolated switching power supply and a switching network, so that remaining power in each monomer battery is adjusted.
Description
Technical field
The utility model relate to a kind of in 5 joint serial connection charge battery pack the circuit of initiatively balanced each cell dump energy.This circuit is got energy from the whole Battery pack that 5 joint rechargeable batteries are composed in series; Through an isolation type switch power and a switching network a certain joint monomer rechargeable battery in the 5 joint serial connection charge battery pack is selectively charged, thereby regulate the dump energy in each cell.
Background technology
Rechargeable battery, like lithium battery etc., when series connection is used in groups, owing to receive production technology, and Effect of Environmental, the dump energy of each cell can not be in full accord.This inconsistency can cause rechargeable battery set shortening discharge time when long-term the use, the charging interval lengthening, and cycle life reduces.At present, in order to overcome this inconsistency, generally adopt the passive equalization methods of conductive discharge formula.This method is switch of parallel connection and a resistance on each cell, and the mode of when charging, through resistance charging current being shunted improves consistency.There is energy dissipation in this passive equalization methods, shortcoming such as the low and caloric value of balanced efficient is big.
Summary of the invention
In order to overcome the energy dissipation that the passive equalization methods of existing battery pack exists; Shortcomings such as the low and caloric value of balanced efficient is big; The utility model provides a kind of active equalizing circuit; Adopt isolation type switch power and switching network, come equilibrium 6 to save the dump energy of each cell in the serial connection charge battery pack through the mode that energy shifts.
The utility model solves the technical scheme that its technical problem adopted: the negative pole of battery Cell1 connects switch S 6 in the series battery; Anodal switch S 1 and the S7 of connecting; The positive pole of battery Cell2 connects switch S 2 and S8; The positive pole of battery Cell3 connects switch S 3 and S9, and the positive pole of battery Cell4 connects switch S 4 and S10, and the positive pole of battery Cell5 connects switch S 5.The other end of switch S 1, S2, S3, S4, S5 links to each other, and connects switch S 11, and the other end of switch S 11 connects the cathode output end OUT+ of isolation type switch power PS.The other end of switch S 6, S7, S8, S9, S10 links to each other, and connects the cathode output end OUT-of isolation type switch power PS.The electrode input end IN+ of isolation type switch power PS connects the positive pole of battery Cell5, and negative input IN-connects the negative pole of battery Cell1.
The beneficial effect of the utility model is in charging and discharge process, through the mode of energy transfer any joint cell is carried out electric weight and replenishes.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the schematic diagram of the utility model.
Among Fig. 1, Cell1, Cell2, Cell3, Cell4, Cell5 are 5 joint rechargeable batteries of series connection.S1, S2, S3, S4, S5, S6, S7, S8, S9, S10, S11 are switches.PS is an isolation type switch power, and IN+ is the electrode input end of PS, and IN-is the negative input of PS, and OUT+ is the cathode output end of PS, and OUT-is the cathode output end of PS.Input IN+ and IN-and output OUT+ and OUT-isolate fully.PS absorbs energy from whole battery group, from output OUT+ and OUT-output equalizing charge electric current.
