As shown in fig. 5, the heat exchange control method for the power conversion station according to the embodiment of the present invention may include the following steps:
s1, identifying the current working condition of the power changing station. The working condition of the current charging station can be a condition of heat dissipation and a condition of heating, and the working condition can be determined according to the temperature inside the charging bin.
According to one embodiment of the invention, the identifying the current working condition of the power swapping station comprises the following steps: and acquiring a first temperature inside the charging bin, and determining the current working condition according to the first temperature. Wherein, acquire the inside first temperature in storehouse that charges, still include: whether the charger is started or not is identified, and when the charger is identified to be started, the first temperature is controlled to be collected.
Further, according to an embodiment of the present invention, determining the current operating condition according to the first temperature includes: comparing the first temperature with a set temperature, and if the first temperature is greater than or equal to the set temperature, identifying the current working condition as a heat dissipation working condition; and if the first temperature is lower than the set temperature, identifying the current working condition as a heating working condition. The set temperature can be calibrated according to actual conditions, for example, the set temperature can be combined with the highest efficiency of the charger for outputting the high voltage of the power battery under any environmental temperature, or the best safety performance of the power battery pack under any environmental temperature.
Specifically, when the charger is started, the charger outputs high voltage to the power battery pack so as to charge the power battery, and at the moment, a first temperature (namely, a sampling point of the first temperature is arranged on the charger) can be acquired through a temperature sensor arranged on the charger, and the first temperature is judged. When the first temperature is greater than or equal to the set temperature, the temperature in the charging bin is higher, and the current working condition of the battery changing station is judged to be a heat dissipation working condition; when the first temperature is lower than the set temperature, the temperature in the charging bin is lower, and the current working condition of the battery replacement station is judged to be a heating working condition.

That is to say, when the current working condition is a heat dissipation working condition, the first ventilation structure in the heat exchange system is controlled to be opened (that is, the common air inlet duct is communicated with the first air outlet duct, and the first check valve is opened), and the second ventilation structure is controlled to be closed (that is, the common air inlet duct is not communicated with the second air outlet duct, and the second check valve is closed), so that air with higher temperature flowing through the charger is discharged outside through the first air outlet duct, and heat dissipation is performed on the charging bin. When the current working condition is a heating working condition, the second ventilation structure in the heat exchange system is controlled to be opened (the common air inlet duct is communicated with the second air outlet duct, and the second check valve is opened), and the first ventilation structure is controlled to be closed (the common air inlet duct is not communicated with the first air outlet duct, and the first check valve is closed), so that air with higher temperature flowing through the charger enters the charging bin through the second air outlet duct to heat the charging bin.
According to an embodiment of the present invention, after controlling the heat exchange system to perform heat exchange according to the target heat exchange mode, the method further includes:
and re-acquiring the first temperature, and judging whether to switch the current target heat exchange mode or not according to the re-acquired first temperature.
