It is described in detail below in conjunction with specific embodiment of the attached drawing to the disclosure.It should be understood that this place is retouched
The specific embodiment stated is only used for describing and explaining the disclosure, is not limited to the disclosure.
Fig. 1 is the flow chart of the Vehicular battery method for heating and controlling provided according to an embodiment of the present disclosure.Such as Fig. 1
Shown, this method may comprise steps of.
In a step 101, it when battery needs to heat, determines and the battery is heated to electric energy required for target temperature
E1 and the battery are heated to after the target temperature compared to the battery available electrical energy E2 that can be promoted before heating.
Illustratively, when battery temperature is less than preset battery temperature threshold value, it may be said that bright present battery needs are heated.
Target temperature can be, for example, above-mentioned battery temperature threshold value, or other numerical value can specifically be set according to actual demand
It is fixed, to this disclosure without concrete restriction.
When battery needs to heat, need to obtain the related energy data that battery is heated to target temperature, with assessment pair
Whether present battery heating can generate advantageous effects.As shown in Fig. 2, may comprise steps of to the determination of E1 and E2:
In step 201, determining remaining electric with current battery temperature, present battery according to preset first corresponding relationship

This corresponding relationship between E1 of remaining capacity, cell health state and environment temperature；
In step 202, determining remaining electric with current battery temperature, present battery according to preset second corresponding relationship
Measure E2 corresponding with present battery health status, wherein the second corresponding relationship is battery temperature, battery dump energy and battery
Corresponding relationship between this three of health status and E2.
For different battery or battery pack, heats, is also not identical as the design in the heat exchange of environment, water route etc..It can be with
A certain temperature (such as preset battery temperature threshold is heated under different operating conditions to different batteries or battery pack by test of many times
Value) consumed by electric energy measure, and obtain above-mentioned first corresponding relationship, and stored, such as form corresponding table, for
Inquiry.In addition, the available electrical energy that battery temperature is promoted after increasing is also variant since battery battery core characteristic is variant.In this regard, can
To improve battery temperature under different operating conditions to target temperature (such as preset battery temperature according to the performance data in battery information
Degree threshold value) after calculated compared to the available electrical energy data promoted before heating, and obtain above-mentioned second corresponding relationship, and by its
Storage, such as forms corresponding table, for inquiry.
From the above mentioned, according to battery temperature, battery dump energy, cell health state and environment temperature, by it is above-mentioned this

In order to the subsequent determination to cell heater control strategy.
In addition, the determination to E1 and E2, can be greater than preset battery dump energy threshold in present battery remaining capacity
It is carried out in the case where value.Wherein, battery dump energy (SOC, State Of Charge) refers to that the active volume in battery accounts for nominally
The ratio of capacity can reflect the state-of-charge of battery.
When battery needs to heat, it can be determined that whether battery dump energy meets the condition determined to E1 and E2.When
It when battery dump energy is greater than preset battery dump energy threshold value, indicates that present battery remaining capacity is enough, is heated in battery
Required battery capacity will not influence power supply of the battery to other electricity consumption modules in the process.E1 and E2 can be determined at this time,
So that subsequent determination is to the control strategy of cell heater, to realize the computer heating control to present battery.
On the contrary, indicating that present battery is surplus if present battery remaining capacity is less than or equal to the battery dump energy threshold value
Remaining electricity is low, and the electric energy that too low battery dump energy value may result in heating consumption is greater than the available electrical energy that battery is promoted.
At this moment if heated to battery, a part in battery available power is used in battery heating, can not provide foot for vehicle
Enough driving powers, it is bad to may result in driving performance.Therefore in this case, need to control cell heater to close shape
State, that is, battery is not heated, to maintain current vehicle power driving power, guarantee the driving performance of current vehicle.
It is carried out in addition, can be to the determination of E1 and E2 in the case where battery heating function is opened.And if battery
Heating function is not opened, i.e. battery heating function is disabled, then cell heater can still be controlled off state.Wherein,
The open and close of the battery heating function can be passed through by user to key, the switch etc. provided on driver's control panel
It is operable to control.Wherein, which can be physical button, the virtual key being also possible on control panel display screen.
Turning now to Fig. 1, in a step 102, as E1 < E2, the control strategy to cell heater is determined.
When E1 is less than E2, i.e., battery is heated to electric energy required for target temperature and is heated to the target temperature less than battery
Compared to the battery available electrical energy that can be promoted before heating after degree, if illustrating for battery to be heated to target temperature, battery available electrical energy
It can be promoted, advantageous effects can be brought to the heating of present battery, at this point it is possible to determine the control strategy to cell heater.
Illustratively, when determining the control strategy to cell heater, cell inlet water temperature and environment temperature can be combined.
Wherein, cell inlet water temperature is the water temperature of battery pack coolant liquid.
Flow chart to the step of the determination of the control strategy of cell heater is as shown in figure 3, can include but is not limited to
Below at least one:
When cell inlet water temperature T emp_water is greater than the first default water temperature threshold value Temp_water1, determine to battery
The control strategy of heater is to close cell heater；
When cell inlet water temperature T emp_water is less than or equal to the first default water temperature threshold value Temp_water1 and is greater than
Second default water temperature threshold value Temp_water2, and current environmental temperature Temp_amb is greater than preset environment temperature threshold value Temp_
When amb_gate, determine that the control strategy of cell heater be control cell heater with the first heating gear operation；
When cell inlet water temperature T emp_water is less than or equal to the first default water temperature threshold value Temp_water1 and is greater than
Second default water temperature threshold value Temp_water2, and current environmental temperature Temp_amb is less than or equal to the preset environment temperature
When spending threshold value Temp_amb_gate, determine to the control strategy of cell heater to be to control cell heater to keep off with the second heating
Position operation；
When cell inlet water temperature T emp_water is less than or equal to the second default water temperature threshold value Temp_water2 and is greater than
Third presets water temperature threshold value Temp_water3, and cell heater current state is when closing, to determine the control to cell heater

When cell inlet water temperature T emp_water is less than or equal to the second default water temperature threshold value Temp_water2 and is greater than
Third presets water temperature threshold value Temp_water3, and cell heater current state is when opening, to determine the control to cell heater
System strategy is kept for control cell heater currently to heat gear operation；
When cell inlet water temperature T emp_water, which is less than or equal to third, presets water temperature threshold value Temp_water3, determine
Control strategy to cell heater is control cell heater with the 4th heating gear operation.
Illustratively, in the disclosure, cell heater is respectively from high to low altogether there are four gear is heated: the 4th heating
Gear, third heating gear, the second heating gear and the first heating gear.Different heating gears respectively correspond different heating
Power, it is correspondingly, also different to the heating intensity of battery.Illustratively, the 4th heating gear, third heating gear, the
Two heating gears and the corresponding heating power of the first heating gear successively reduce, and in turn, add corresponding to this four gears
Calorific intensity also successively reduces.
As described above, in the first scenario, when cell inlet water temperature T emp_water is greater than the first default water temperature threshold value
When Temp_water1, determine that the control strategy of cell heater be to close cell heater.It is because in cell inlet in this way
In the case that water temperature is greater than the first default water temperature threshold value, if heating to battery, excessively high cell inlet water temperature be may lead
Play safety problem.
In the latter case, when cell inlet water temperature T emp_water is less than or equal to the first default water temperature threshold value
Temp_water1 is simultaneously greater than the second default water temperature threshold value Temp_water2, and current environmental temperature Temp_amb is greater than default
Environment temperature threshold value Temp_amb_gate when, illustrate that the temperature of present battery coolant liquid is not very low, and external environment temperature
Degree is nor very low, at this point, demand of the battery to heating power is little, cell heater adds battery with lower heating power
Heat, it is thus determined that being to control cell heater to heat gear (illustratively, most with first to the control strategy of cell heater
Low gear) operation.
In a third case, when cell inlet water temperature T emp_water is less than or equal to the first default water temperature threshold value
Temp_water1 is simultaneously greater than the second default water temperature threshold value Temp_water2, and current environmental temperature Temp_amb is less than or waits
When the preset environment temperature threshold value Temp_amb_gate, illustrate that current outside environment temperature is lower, at this point, compared to
Second situation, demand of the battery to heating power increased, accordingly, it is determined that being control to the control strategy of cell heater
Cell heater is with the second heating gear (compared to second situation, increasing a gear) operation.
In the fourth case, when cell inlet water temperature T emp_water is less than or equal to the second default water temperature threshold value
Temp_water2 is simultaneously greater than the default water temperature threshold value Temp_water3 of third, and cell heater current state is when closing, to say
The temperature of bright present battery coolant liquid is lower, needs to heat battery with bigger heating power, it is thus determined that electricity
The control strategy of pond heater is control cell heater with third heating gear operation.
In a fifth case, when cell inlet water temperature T emp_water is less than or equal to the second default water temperature threshold value
Temp_water2 is simultaneously greater than the default water temperature threshold value Temp_water3 of third, and cell heater current state is when opening, to say
Although the temperature of bright present battery coolant liquid is lower, the continuous heating of cell heater in the open state can be with
Heating process is completed, it is thus determined that being that control cell heater is kept currently to heat gear to the control strategy of cell heater
Operation.
In a sixth case, water temperature threshold value is preset when cell inlet water temperature T emp_water is less than or equal to third
When Temp_water3, illustrate that the temperature of present battery coolant liquid is too low, needs to be heated with maximum heating power, therefore
Determine that the control strategy of cell heater be control cell heater with the 4th heating gear (i.e. highest heating gear) operation.
In addition, the case where being directed to E1 >=E2, can determine when receiving the battery heat request of user's input to electricity
The control strategy of pond heater.
When E1 is greater than or equal to E2, i.e. battery is heated to electric energy required for target temperature and is heated more than or equal to battery
When after to the target temperature compared to the battery available electrical energy that can be promoted before heating, if illustrating battery being heated to target temperature,
The effect is unsatisfactory for the promotion of battery available electrical energy, at this time, it may be necessary to further determine whether that the battery for receiving user's input heats
Request.The battery heat request can be by user by grasping to key, the switch etc. that provide on driver's control panel
Make and provides.Wherein, which can be physical button, the virtual key being also possible on control panel display screen.Work as reception
When to battery heat request, illustrate that user has demand heat to battery, at this point it is possible to control of the determination to cell heater
Strategy.The correlation step of the determination of the control strategy of cell heater is hereinbefore had been described, is not repeated.
On the contrary, if not receiving battery heat request, illustrating that current vehicle does not have in the case where E1 is greater than or equal to E2
