As shown in fig. 1, a charging control method for an electric vehicle, applied to an electric vehicle equipped with a cold liquid battery, includes:
and 14, calculating a time difference value between the first time and the second time, and determining the time for starting temperature control on the battery according to the time difference value.
For example, when the electric vehicle detects that the destination of the vehicle-mounted navigation is not the charging pile, the first time required by the current vehicle to reach the charging pile is calculated, then the current temperature of the battery is detected, or the temperature of the vehicle when the vehicle reaches the charging pile can be further estimated, and then whether the temperature control of the battery is needed or not is judged. And if the temperature of the battery needs to be controlled, calculating second time required for adjusting the current temperature of the battery or the temperature reaching the budget of the charging pile to a preset temperature interval, comparing the first time with the second time, and determining the time for starting temperature control of the battery.
According to the charging control method of the electric automobile, whether the temperature of the battery needs to be controlled or not is judged by detecting the temperature of the battery, and then the time for starting the temperature control of the battery is calculated by comparing the distance from the battery to a charging device with the time for adjusting the temperature of the battery to a preset temperature area. When the temperature reaches the target value, the battery is in a heat preservation state, and meanwhile, the temperature control of the battery is stopped after the charging opening cover is detected to be opened, so that the fault caused by the temperature control of the battery in the charging process is prevented. The electric vehicle charging control method provided by the embodiment of the invention can adjust the battery pre-charging temperature in winter and summer, provides full-weather charging control for the electric vehicle, can ensure that the electric vehicle can be charged at the maximum charging rate in a full-weather environment, shortens the charging time of the electric vehicle, reduces the charging waiting time of a user, saves the energy consumption in the battery temperature control process and greatly improves the experience and experience of the user.
Optionally, before the first time required for the vehicle to travel to the charging pile set by the vehicle navigation system is calculated, the method further includes:
under the condition that the destination set by the vehicle-mounted navigation system includes the position of the charging pile, acquiring the current residual electric quantity of the vehicle and first energy consumption required by the vehicle to travel from the current position to the position of the charging pile;
calculating a difference value between the residual electric quantity and the first energy consumption, and judging whether the difference value is smaller than a preset charging threshold;
and when the difference value is smaller than the charging threshold, the step of calculating the first time required by the vehicle to travel to the charging pile set by the navigation system is carried out, otherwise, the process is ended.
For example, first energy consumption required by the vehicle to drive to the charging pile is calculated, then the current remaining power of the vehicle is detected, a difference between the remaining power and the first energy consumption is calculated, if the difference is greater than or equal to a preset charging threshold, whether the temperature control of the battery is required is judged, but if the difference is smaller than the preset threshold, it is proved that the remaining power of the vehicle may not be enough to support the vehicle to drive to the charging pile or the battery can reach the charging pile barely, so the temperature control of the battery is not considered in this case.
Optionally, the determining whether temperature control of the battery is required includes:
if the temperature of the battery is within the preset temperature interval, temperature control on the battery is not needed;
and if the temperature of the battery is not within the preset temperature interval, the temperature of the battery needs to be controlled.
For example, the preset temperature range is 15 to 35 degrees celsius, and the temperature of the battery needs to be controlled when the temperature of the battery is lower than 15 degrees celsius or higher than 35 degrees celsius, otherwise, the temperature of the battery does not need to be controlled.
Optionally, the temperature controlling the battery includes:
if the temperature of the battery is lower than the minimum value of the preset temperature interval, heating the battery;

if the time difference value is a negative value or zero, performing temperature control on the battery;
and if the time difference is a positive value, controlling the temperature of the battery after the duration of the time difference.
For example, if the time required for the vehicle to reach the charging pile is 25min, it takes 15min for the temperature control of the battery to reach the preset temperature interval, and the time difference can be calculated to be 10min, then the temperature control of the battery is started after 10 min; if the time required by the vehicle to reach the charging pile is 5min, the time required by controlling the temperature of the battery to reach the preset temperature interval is 15min, and then the temperature of the battery is immediately controlled.
Optionally, the method further comprises:
when the time difference value is a negative value or zero, stopping temperature control on the battery after the vehicle runs to a charging pile set by a navigation system;
and when the time difference value is a positive value, maintaining the temperature of the battery after the temperature of the battery enters the preset temperature interval.
Optionally, the method further comprises:
and when the opening of the vehicle charging opening cover is detected, stopping the temperature control of the battery.
As shown in fig. 2, in the electric vehicle charging control method according to the embodiment of the present invention, when a vehicle owner prepares to charge a vehicle, and sets a destination charging pile in a vehicle-mounted navigation system, the navigation system starts to calculate a first time required to reach the destination, and meanwhile, the vehicle detects a battery temperature and calculates a second time required to heat (or cool) to a suitable preset temperature range. And obtaining the moment of starting the battery heating (refrigerating) system according to the difference value of the two times. When the time is reached, the vehicle starts the battery to heat (refrigerate), if the charging opening cover is opened in the process, the battery is stopped to heat (refrigerate), otherwise, the temperature is continuously controlled to the target temperature, and if the destination is not reached, the vehicle enters a battery heat preservation state.
For example, when the time difference is a negative value, or zero, that is, the time required for the vehicle to reach the charging pile is less than or equal to the time required for the temperature control of the battery to reach the preset temperature interval, the temperature control of the battery is stopped when the vehicle reaches the charging pile, and further, the temperature control of the battery is stopped after the vehicle detects that the charging cover is opened; when the time difference is a positive value, namely the time required for the vehicle to reach the charging pile is longer than the time required for the battery to be subjected to temperature control to reach a preset temperature interval, the temperature of the battery is monitored in real time, and when the temperature of the battery reaches the preset temperature interval, a heat preservation mode is entered to maintain the current temperature of the battery.
