Art.
Presently relevant battery heating technique is that firing equipment is powered by external power supply, can be filled after the completion of heating
Electricity, but have the disadvantage to need additional power supply, this undoubtedly adds holistic cost, and is needing to be filled according to charge protocol
Can not be according to charging normal flow implementation in the DC charging equipment of electricity communication.
The content of the invention
One of purpose of the present invention is a kind of electric automobile power battery charging heating system of proposition, it is adaptable to connected
The electric automobile power battery system of DC charging motor, can be supplied by electrokinetic cell dump energy and charger for heater
Electricity.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of electric automobile power battery charging heating system
System, including battery management system, power battery pack, filled in the firing equipment and direct current of the power battery pack for providing heat energy
Motor；The battery management system is to be electrically connected with the DC charging motor, power battery pack；The DC charging is electromechanical
Property the connection power battery pack；The power battery pack, firing equipment, DC charging motor share same bus.
It is preferred that, the firing equipment is passes through the equipment that heat energy is provided for power battery pack of DC-voltage supply.
It is preferred that, open battery management system and DC charging motor information exchange, the power after the DC charging motor
The dump energy and DC charging motor of battery pack are powered to heating system simultaneously, and DC charging motor charges to power battery pack, are led to
It is that heating system is powered down to cross electrokinetic cell dump energy and charger, throws away and carries out information exchange according to original charge protocol,
Original charging flow is not interrupted, it is simple easily to realize.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art：
The electric automobile power battery charging heating system of the present invention program, it is adaptable to connect the electronic vapour of DC charging motor
Car electrokinetic cell system, is powered by electrokinetic cell dump energy and DC charging motor for heater, and still can be according to original
There is charge protocol to carry out information exchange, original charging flow is not interrupted, heating means are simply easily realized.
Brief description of the drawings
Technical solution of the present invention is described further below in conjunction with the accompanying drawings：
Accompanying drawing 1 arranges schematic diagram for the structure of the electric automobile power battery charging heating system of the present invention；
Accompanying drawing 2 is the execution flow chart schematic diagram of the electric automobile power battery charging heating system of the present invention.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the present invention is described in further detail.
A kind of electric automobile power battery charging heating system of the present invention as shown in accompanying drawing 1,2, including battery
Management system, power battery pack, for providing heat energy in the firing equipment and DC charging motor of the power battery pack；Cell tube
Reason system is to be electrically connected with the DC charging motor, power battery pack；DC charging motor is electrically connected with the electrokinetic cell
Group；Power battery pack, firing equipment, DC charging motor share same bus.Wherein firing equipment is to be supplied by DC voltage
The equipment that heat energy is provided for power battery pack of electricity.
Using the heating means of above-mentioned electric automobile power battery charging heating system, the remaining electricity of electrokinetic cell can passed through
Amount and charger are that heater is powered down, throw away and carry out information exchange according to original charge protocol, and original charging stream is not interrupted
Journey, heating means are simply easily realized.The heating means of specific heating system comprise the following steps：
Step S1, DC charging motor connection power battery pack is opened battery management system after DC charging motor and filled with direct current
Motor information exchange, closure positive and negative electrode relay enters the stage that charges normal, and performs step S2；
Step S2, battery management system detection battery bulk temperature, and judge whether battery minimum temperature needs less than heating
Temperature threshold is sought, demand for heat temperature threshold is the lowest temperature angle value that battery allows to be charged, if then performing step S3, if
It is not then to perform step S5；
Step S3, performs heating, firing equipment work, adhesive heating relay, the power battery pack, firing equipment,
DC charging motor shares same bus, sets charge requirement electric current to be less than heated current 1A, and heated current is heating load work
Make electric current, charge requirement current information is sent to DC charging motor, DC charging motor is performed after demand current, battery will continue
Export 1A discharge currents, it is to avoid low temperature charges, into step S4；
Step S4, judges whether battery minimum temperature completes temperature threshold higher than heating, and it is big that heating, which completes temperature threshold,
In 2~5 DEG C of temperature value of demand for heat temperature threshold, if then performing step S5, if not then proceeding heating；
Step S5, stops heating, disconnects heating relay, sends normal charging current demand.
Wherein this method is suitable for use with the electric powered motor electricity that direct-current charging interface is connected with external dc charger
In cell system.
Battery management system and DC charging motor information exchange after DC charging motor are opened, no matter currently whether needs to add
Heat, can close the entrance of positive and negative electrode relay and charge normal the stage.Into charging normal after the stage, system only need to be according to being
No to need to heat and calculated after charging current according to heated current, change charge-current demands are sent to DC charging motor i.e.
Can, overall charging flow only need to change charge-current demands without changing with heating process.Demand for heat temperature threshold is battery
Allow the lowest temperature angle value charged, heating completes the temperature that temperature threshold is 2~5 DEG C more than demand for heat temperature threshold
Value.Electrokinetic cell dump energy and DC charging motor are powered to heating system simultaneously, when battery is heated, and charge requirement electric current is low
In heated current 1A, wherein heated current is heating load operating current, and charger is performed after demand current, and battery will continue defeated
Go out 1A discharge currents, it is to avoid low temperature charging causes damage to battery.
It the above is only the concrete application example of the present invention, protection scope of the present invention be not limited in any way.It is all to use
Technical scheme formed by equivalent transformation or equivalent replacement, all falls within rights protection scope of the present invention.
