A charging control method according to an embodiment of the third aspect of the invention is described below with reference to the drawings. Wherein, when charging, charging device for example fills electric pile and is connected with the on-vehicle socket that charges of above embodiment through charging the connector.
Fig. 5 is a charging control method according to an embodiment of the present invention, and as shown in fig. 5, the charging control method of the embodiment of the present invention includes at least step S1, step S2, and step S3.
And step S1, collecting a charging temperature value.
Specifically, after entering the charging process, the temperature detection element collects the current ambient temperature, such as Ti, and sends the collected ambient temperature to the controller, and the controller sets the Ti as the starting point of temperature control. The charging temperature value is the temperature value of the highest temperature point of the charging plug male end acquired by the temperature detection part, and needs to be acquired continuously in the temperature acquisition process, and the acquired temperature value is output to the controller continuously.
In step S2, a temperature range of the charging temperature value is determined.
Specifically, after the temperature detection piece collects the charging temperature value of the current charging plug male end, the temperature detection piece judges the charging temperature value, determines the temperature range of the temperature value and charges the temperature value by adopting different charging currents.
In the temperature range in this embodiment, compared with the temperature range of the temperature protection strategy in fig. 2, the temperature range is divided more finely, the temperature range in fig. 2 is only divided into the protection temperature and the highest temperature, after the temperature detection element detects that the current charging temperature value is greater than the protection temperature, the charging protection mode is directly entered, the charging current is controlled to gradually decrease from the maximum current to 0, the temperature protection strategy only protects serious faults such as over-temperature burning of the charging connector, so that the use effect of the charging connector is rapidly deteriorated once the charging connector is damaged, and the performance is exponentially decreased. As shown in fig. 6, which is a schematic diagram of a temperature protection strategy according to an embodiment of the present invention, a protection temperature TP, a maximum temperature Tmax, a determination temperature Tj, a buffer temperature Tb, and a charging stop temperature Ts are respectively set with Ti as a temperature starting point. Wherein, the protection temperature TP is a starting point for limiting the charging temperature; the maximum temperature Tmax is the maximum temperature point tolerated by the connector; the judgment temperature Tj is a temperature point for judging that the charging performance is invalid, and a temperature detection precision point at which the judgment temperature Tj should be greater than the highest temperature Tmax is judged, and according to the comparison between the currently acquired charging temperature value and a set temperature range, the temperature range in which the currently acquired charging temperature value is located is judged, the division of the temperature range fully considers the material performance of the charging connector, and the use state of the charging connector is more reasonably controlled.
In step S3, the charging current is adjusted according to the temperature range.
In the charging process, the charging temperature value can be continuously changed along with the increase of the charging time, the temperature range of the collected charging temperature value is determined, and the charging current is adjusted according to the temperature range.
According to the charging control method provided by the embodiment of the invention, the temperature detection piece is arranged in the jack through the switching component in the vehicle-mounted charging socket, so that the temperature detection piece can accurately acquire the charging temperature value, data support is provided for accurately acquiring the charging temperature value, meanwhile, the temperature range is more accurately divided, after the charging temperature value is acquired, the current charging current is adjusted according to the temperature range of the charging temperature value, and the safety of the charging process is improved while the charging connector is protected.
In some embodiments, adjusting the charging current according to the temperature range includes controlling the charger to output a maximum allowable charging current when the charging temperature value is less than the protection temperature threshold; or when the charging temperature value is greater than the protection temperature threshold and less than the maximum temperature threshold, entering a charging protection mode, and controlling the charger to output a first charging current in the charging protection mode, wherein the first charging current is greater than the minimum allowable charging current and less than the maximum allowable charging current; or when the charging temperature value is greater than the maximum temperature threshold and less than the charging failure temperature threshold, entering a charging performance failure judgment mode, and controlling the charger to output a second charging current in the charging performance failure judgment mode, wherein the second charging current value is less than the minimum allowable charging current; or when the charging temperature value reaches the charging allowable temperature limit value, controlling the charging gun to stop charging; or when the charging temperature value is larger than the highest temperature range of the temperature detection piece, or when the charging temperature value is smaller than the lowest temperature range of the temperature detection piece, the charging gun is controlled to stop charging.
Specifically, in the charging start stage, if the collected charging temperature value is smaller than the protection threshold Tp, in order to reduce the charging time, the charger is controlled to output the maximum current Imax for charging in the charging start stage, the charging temperature also increases with the increase of the charging time, when the charging temperature value is greater than the protection temperature threshold Tp but smaller than the maximum temperature threshold Tmax, the charging protection mode is entered, and at this time, the charger is controlled to reduce the charging current from Imax to a first charging current, the first charging current is between the minimum allowable charging current Imin and the maximum allowable charging current Imax, and in a normal case, the minimum allowable charging current Imin is a user-defined value as required by a user. In the charge protection mode, the temperature may rise from Tp to Tmax as the charging time increases, and the charging current gradually decreases during the time, and in order to minimize the extension of the charging time, the curve is defined as a flexible variation interval, in other words, the charging current rises as the temperature decreases until the equilibrium is reached.
When the charging is carried out by the first charging current, the charging temperature may continuously rise along with the increase of the charging time, when the charging temperature reaches the maximum temperature threshold Tmax and is less than the charging failure temperature threshold Tj, the charging performance failure judgment mode is entered, the charging current of the charger is controlled to be the second charging current, the charging performance failure is prompted through the controller, and in addition, the charging failure temperature threshold Tj is a temperature detection precision point which is greater than the maximum temperature threshold Tmax. In order to avoid direct charging stop caused by response delay, the low-speed charging is still carried out at the second charging current before the temperature reaches Tb. Wherein the second charging current is at least 50% lower than the minimum allowable charging current Imin.
And if the temperature of the connector still rises to or above the charging stop temperature Ts after the low-speed charging mode is entered, controlling the charging gun to directly stop charging.
When the temperature detection piece is failed in a short circuit, the charging temperature value is far larger than the maximum temperature range of the temperature detection piece, when the temperature detection piece is failed in an open circuit, the charging temperature value is far smaller than the minimum temperature range of the temperature detection piece, and the charging gun is controlled to stop charging.
Further, when the charger is detected to enter the charging performance failure judgment mode or stops charging, a charging abnormity prompt, such as a voice prompt, is performed.
In some embodiments, the charging control method further comprises calculating a temperature change rate according to the charging temperature value when the charger outputs the maximum allowable charging current; and when the temperature change rate reaches a preset temperature change threshold value, controlling the charger to enter a charging protection mode.
Specifically, the calculation formula of the temperature change rate Vi is (Tn-Ti)/[ delta ] t, where [ delta ] t is the charging period. When the charging is carried out at the maximum allowable current Imax in the charging starting stage, the charging temperature value is recorded in real time according to the charging time length, the temperature change rate Vi is calculated according to the recorded temperature value and the charging time length, and if the temperature change rate Vi is larger than the upper limit value of the self temperature change resistance impact before the temperature of the connector reaches the protection temperature Tp, the current temperature of the connector is immediately set to Tp and the charging protection mode is entered.
The following describes the current control temperature protection method according to an embodiment of the present invention in detail with reference to fig. 7, which is a flowchart of the current control method according to an embodiment of the present invention, as shown in fig. 7.
And step S10, the temperature acquisition detection piece acquires the charging temperature value Tn in real time.
Step S11, continuously outputting the charging temperature value Tn to the controller, and executing step S12 if the charging temperature value Tn exceeds the range; if not, go to step S13.
And step S12, directly controlling the charging gun to stop charging.
Step S13, determining a temperature range of the charging temperature value Tn, and if the charging temperature value Tn is smaller than the protection temperature Tp, executing step S14; if the charging temperature value Tn is greater than the charging temperature value Tn, step S12 is executed.
