When threshold value, control device then passes through control first switch and the second switch, and coolant liquid is made to flow through the temperature control zone of battery body
Road thus can achieve the purpose heated to battery body, while also accelerate the cooling velocity of coolant liquid.When at once parking is filled
When electric, battery body is still maintained at a relatively comfortable temperature environment, greatly shortens the charging time.
Second: hybrid vehicle is travelled shorter using pure power mode or traditional mode (engine driving form mode)
Time (engine coolant temperature be not up to temperature heat to battery body or to battery body heating temperature is less than can be straight
When connecing charging temperature, i.e., the temperature of engine coolant is lower than second temperature threshold value), battery body is heating by external power supply
Piece power supply guarantees that battery system can be fully charged to heat to battery body.
Situation two: the heating function before electric discharge:
When hybrid vehicle is travelled using traditional mode, when the coolant temperature of engine reaches second temperature threshold value,
Control device then passes through control first switch and the second switch, so that coolant liquid is flowed through the temperature control lines of battery body, to electricity
Pond ontology is kept the temperature.When being switched to pure power mode, battery body is in a relatively comfortable environment and discharges at this time, this is not

Step 201: connecting the anode of extraneous power supply in the charging anode, and the charging cathode connects extraneous power supply
When cathode, judge the first temperature of the first temperature sensor acquisition whether more than the first temperature threshold.
Wherein, since heating sheet is integrated between the charging anode of battery body and charging cathode, so, heating sheet is
External power supply when being charged by hybrid vehicle is powered.Therefore, the heating circuit that heating sheet is constituted, only exists
The anode that charges of battery body connects the anode of extraneous power supply, and could be electricity when the cathode for the extraneous power supply of cathode connection that charges
Pond ontology is heated.
In addition, when battery body is specifically heated, it can be by the way that the first temperature inside battery body be arranged in
Sensor detects the actual temp of battery body, and is sent to control device, so that control device judges the first temperature sensor
Whether the first temperature sent when be less than first temperature threshold, just can indicate battery body temperature more than the first temperature threshold
It spends lower, needs to heat.
Step 202: when first temperature is less than first temperature threshold, according to the second temperature sensor

That is, control device controls first switch and the second switch and opens when second temperature is more than second temperature threshold value, make
The coolant liquid for obtaining engine can be flowed into the temperature control lines near battery body, pass through the temperature of engine coolant
Degree is that battery body is heated；When second temperature is less than second temperature threshold value, control device controls first switch and the
Two close the switch, i.e., so that engine coolant cannot be introduced into temperature control lines, and control the 5th and close the switch, so that
Circuit conducting where heating sheet, heating sheet generates heat, to heat for battery body.
It follows that the embodiment of the present invention, the second temperature sent by control device according to second temperature sensor
(i.e. the actual temperature of engine coolant) selects any mode is specifically used to be heated for battery body, so as to
So that the temperature of battery body promotes the temperature allowed to charging at any time.
Further, using heating sheet be battery body heated when, if the temperature of battery body have reached it is fair
Perhaps after charging temperature, continue to heat, may result in that battery body temperature is excessively high, will affect the property of entire battery system
Can, and reduce the service life of battery body.It therefore, is being also to need in battery after battery body is heated using heating sheet
After body temperature reaches certain temperature, stopping heats it, that is, disconnects the conductive path of heating sheet.
Therefore, the first switch is controlled in above-mentioned control device and the second switch is closed, and control the described 5th
After the step of switch is closed, further includes: judge whether first temperature is more than first temperature threshold, and described the
When one temperature is more than first temperature threshold, controls the 5th switch and open.
