Summary of the invention
The technical problem to be solved in the present invention is, at the deficiencies in the prior art, proposed a kind of battery of electric vehicle list and filled and continue the combo method.
Technical scheme of the present invention is that a kind of battery of electric vehicle list fills and continues the combo method, it mainly comprises two aspects: the one, change whole group of present serial connection charge mode, and charge separately by each cell that the whole group of the battery pack of electric motor car serial connection charge is made into to the battery pack of one or more electric motor cars; The 2nd, be not limited to the battery pack initial assembly of dispatching from the factory, assembly is continued at any time according to the detection gained parameter to each cell in each charging back, forms the new conforming battery pack of height and comes into operation.
Concrete technical scheme is that battery of electric vehicle list of the present invention fills and continues the combo method, series conductor to the battery of electric vehicle group is transformed into the easily assembling type, before charging, series conductor between each single battery of car load battery pack is dismantled, with small-sized charger a plurality of and the monomer battery voltage coupling, each cell is charged separately by technical specification, the present invention is according to the detection data to each cell, each cell is charged separately targetedly, intelligent charging machine under the prior art condition, very easily each cell is realized at least filling automatically, fill less at most, Man Zeting fills, and charging finishes every battery detecting is drawn voltage, performance parameters such as capacity.
Above program can be carried out in the battery pack of an electric motor car, also can carry out in the battery pack of many electric motor cars.And next program on this basis must be carried out between the battery pack of many electric motor cars.Promptly according to the parameter that single battery detecting is drawn, in the scope that exceeds a battery of electric vehicle group quantity, as required each cell is joined again, major parameter is reassembled into new battery pack such as identical or the most approaching cells such as voltage, capacity, connect series conductor again, entrucking is used.Described continuation assembly method is meant the assembly again and again afterwards of dispatching from the factory that battery pack is done, and carries out repeatedly in the whole life of battery of electric vehicle group.
The invention has the beneficial effects as follows that described battery of electric vehicle list fills and continues the combo method, can progressively solve the battery of electric vehicle consistency problem from three aspects:
At first at the battery of electric vehicle group in the discharge process that travels, since discharged in series must to have limitation to form between each cell discharge unbalanced, each cell is in the electric motor car different parts and causes the different or other reasons of poor working environment to cause inconsistency between the cell in addition, the present invention is according to the detection data to each cell, each cell is charged separately targetedly, thereby solved the source part of battery of electric vehicle consistency problem;
Next is that the monomer mise-a-la-masse method can effectively avoid charging process to produce consistency problem at each cell that traditional serial connection charge method in the past is easy to generate inconsistent problem of charging;
The 3rd is disposable battery group typing before dispatching from the factory for traditional battery of electric vehicle group, unless indivedual cells are scrapped and are changed in the battery pack cycle in useful life, the consistency problem that is caused by discharge and charging process and other factors spreads unchecked, cause the actual cycle of battery of electric vehicle group to charge and discharge the life-span and be significantly less than the situation of theoretical value, continuous assembly method of the present invention is carried out new consistency assembly to individual cell to the back of charging at any time according to detecting data, and in the whole life of battery of electric vehicle, carry out repeatedly, can effectively get rid of the short slab effect, to a battery of electric vehicle consistency difficult problem, the approach of technology barrier has been proposed to break through from method.
Because described continuation assembly method is at many even may is to carry out between the battery of electric vehicle group of extensive quantity, so be different from the complicated work of motor vehicle repair formula case, the present invention can be with the whole power technology problem that solves all participation vehicles of a kind of reciprocal form.
Because battery of electric vehicle list of the present invention fills and to continue the battery pack quantity of combo method participation assembly big more, can improve the assembly effect more, means that the present invention can launch benefit in the benign cycle mode.
