Description

A kind of echelon of accumulator of electric car uses exchange technology
Technical field
Technical field is exchanged the invention belongs to battery, and in particular to a kind of echelon of accumulator of electric car uses exchange skill Art.
Background technology
The battery used on electric automobile, structural capacity is reduced to less than 50%, is just difficult to be continuing with.Under these Car battery is transplanted to other energy storage places, can still there is actual benefit.But can not possibly directly be shifted in actual motion can To use;Its reason mainly has:The physical dimension and the groups of single-unit quantity of series connection of 1 cell, in existing energy storage place " just " is difficult to be applicable.2 BMS installed in energy storage place, the usable interface quantity of control line, if after adapting to restructuring Battery pack;In place of in view of the shortcomings of the prior art, it is necessary to develop a kind of electric power storage for that can not continue to be used in electric motor car The recycling in pond, and the echelon for controlling battery upper and lower bound to protect the accumulator of electric car of lithium battery uses exchange skill Art.
The content of the invention
The invention aims to overcome the deficiencies in the prior art, and one kind is provided for that can not continue in electric motor car The recycling of the battery for using and control battery upper and lower bound protect the echelon of the accumulator of electric car of lithium battery Use the technology of exchange.
The object of the present invention is achieved like this:1st, a kind of echelon of accumulator of electric car uses exchange technology, and it is special Levy and be:The echelon is the electric single-unit state for the battery got off being decomposed parallel connection using exchange technology, is then rejected The underproof single-unit of structural capacity, according to the border that the voltage standard and installing space of energy storage device are allowed, is reassembled into small The battery strings of capacity
The original BMS of energy-storage system of the battery is not required to change, and keeps original voltage bound control data, this electricity Pond string can be directly parallel in the energy-storage battery group of operation.
By taking 72V electric power systems as an example, with the lead-acid battery that first wife puts it is used at the same time under the conditions of, lead-acid battery charge Lower voltage limit when upper voltage limit and electric discharge, the just less than permissible value of lithium battery.
Using the control standard of lead-acid battery, lithium battery can be without BMS;Simply the single-unit quantity of lithium battery is less than plumbic acid Battery.
Beneficial effects of the present invention:In the present invention:1 battery got off puts the electric single-unit shape for decomposing parallel connection State, rejects the underproof single-unit of structural capacity, according to the border that the voltage standard and installing space of energy storage device are allowed, again group Synthesize the battery strings of low capacity;Original BMS is not required to change, and keeps original voltage bound control data, this battery strings Can directly be parallel in the energy-storage battery group of operation;2 with the lead-acid battery that first wife puts it is used at the same time under the conditions of, plumbic acid electricity The lower voltage limit when upper voltage limit that pond is charged and electric discharge, the just less than permissible value of lithium battery;Using the control of lead-acid battery Standard, lithium battery can be without BMS;The single-unit quantity of lithium battery is less than lead-acid battery;The data of diagram are exactly that 72V is powered to be The mixed analysis of the battery of system;To communication base station 48V electric power systems analyze, can also obtain just as conclusion;Therefore, present invention tool There are the recycling for the battery that can not continue to be used in electric motor car, and control battery upper and lower bound to protect lithium electricity The echelon of the accumulator of electric car in pond uses the advantage of exchange technology.
Brief description of the drawings
Fig. 1 is that the present invention uses analysis principle figure with to the battery of 72V electric power systems.
Specific embodiment
The present invention is described further below in conjunction with the accompanying drawings.
Embodiment 1
As shown in figure 1, a kind of echelon of accumulator of electric car uses exchange technology, the echelon is under using exchange technology The battery of car decomposes the electric single-unit state of parallel connection, the underproof single-unit of structural capacity is then rejected, according to energy storage device Voltage standard and installing space allow border, be reassembled into the battery strings of low capacity.
In the present invention:1 battery got off decomposes the electric single-unit state of parallel connection, rejects structural capacity unqualified Single-unit, according to energy storage device voltage standard and installing space allow border, be reassembled into the battery strings of low capacity;It is former Some BMS are not required to change, and keep original voltage bound control data, this battery strings to be directly parallel to the storage of operation In energy battery pack;2 with the lead-acid battery that first wife puts it is used at the same time under the conditions of, lead-acid battery charge upper voltage limit and electric discharge When lower voltage limit, the just less than permissible value of lithium battery;Using the control standard of lead-acid battery, lithium battery can be without BMS; The single-unit quantity of lithium battery is less than lead-acid battery;The data of diagram are exactly to use analysis with to the battery of 72V electric power systems;To logical Letter base station 48V electric power system analyses, can also obtain just as conclusion;The advantage of this technology is:1 pair of capacity declines and can not continue The battery used on electric automobile, the battery strings that can constitute low capacity are used for energy storage;2 controls for utilizing lead-acid battery Upper and lower bound, can protect lithium battery that overcharge and overdischarge do not occur;Therefore, the present invention has for that can not continue in electricity The recycling of the battery used on motor-car, and control battery upper and lower bound to protect the accumulator of electric car of lithium battery Echelon using exchange technology advantage.
