Description

Cell management system of electric automobile
Technical field
This utility model belongs to battery of electric vehicle management technique field, particularly relates to a kind of batteries of electric automobile management and is System.
Background technology
Existing battery management system simply carries out charge and discharge control to power battery pack simply, so influences whether power The service life of set of cells.
Utility model content
In view of the above problems, the purpose of this utility model is to provide a kind of cell management system of electric automobile, it is intended to solve Certainly existing battery management system cannot rationally carry out the technical problem of set of cells control.
This utility model is achieved in that described cell management system of electric automobile, including charger, electrokinetic cell Group, motor driver, be provided with the first control switch, described power battery pack and motor between described charger and power battery pack It is provided with the second control switch between driver, also includes:
Acquisition Circuit, for gathering the electric current of power battery pack, voltage, internal resistance and temperature data;
CPU, for receiving the voltage of described power battery pack, electric current, internal resistance and temperature data, and controls the control of correspondence Switch on-off;
Wherein, described control switch includes a N-MOS pipe and the 2nd N-MOS pipe, a N-MOS pipe drain electrode and the 2nd N- The drain electrode of metal-oxide-semiconductor is connected, and the source electrode of a N-MOS pipe is connected with load negative pole, a N-MOS tube grid and the 2nd N- Metal-oxide-semiconductor grid is all connected with CPU.When set of cells is carried out discharge operation, a N-MOS pipe conducting, the 2nd N-MOS manages not Conducting;When set of cells is charged operation, a N-MOS pipe is not turned on, the 2nd N-MOS pipe conducting;When battery cell electricity Be pressed be short-circuited above or below predetermined threshold value or set of cells or cross stream time, the oneth N-MOS pipe and the 2nd N-MOS pipe do not lead Logical.
The beneficial effects of the utility model are: this utility model can turn off the control of correspondence and open when battery exists fault Close, reach to close charge circuit and the purpose of discharge loop of power battery pack, by rationally monitoring power battery voltage, electricity Stream, internal resistance, temperature, be conducive to extending the service life of power battery pack.
Accompanying drawing explanation
Fig. 1 is the structure chart of cell management system of electric automobile;
Fig. 2 is the structure chart controlling switch.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain This utility model, is not used to limit this utility model.
As it is shown in figure 1, the cell management system of electric automobile that this utility model provides includes that charger 1, first controls to open Pass 2, power battery pack 3, second control switch 4, motor driver 5, are provided with between described charger 1 and power battery pack 3 First control switch 2, be provided with between described power battery pack 3 and motor driver 5 second control switch 4, also include:
Acquisition Circuit 6, for gathering the electric current of power battery pack, voltage, internal resistance and temperature data;
CPU7, for receiving the voltage of described power battery pack, electric current, internal resistance and temperature data, and controls the control of correspondence System switches on-off;
As in figure 2 it is shown, control switch to include N-MOS pipe 8 and a 2nd N-MOS pipe 9, N-MOS pipe 8 drain electrode and the The drain electrode of two N-MOS pipes 9 is connected, the source electrode of a N-MOS pipe 8 with load negative pole be connected, N-MOS pipe 8 grid and 2nd N-MOS pipe 9 grid is all connected with CPU.When set of cells is carried out discharge operation, a N-MOS pipe 8 turns on, and second N-MOS pipe 9 is not turned on;When set of cells is charged operation, a N-MOS pipe 8 is not turned on, and the 2nd N-MOS pipe 9 turns on; When battery cell voltage has more than or is less than predetermined threshold value or set of cells is short-circuited or crosses stream, a N-MOS pipe 8 and second N-MOS pipe 9 is all not turned on.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model Protection domain within.
