In the embodiment of the present application, after battery pack device starting dehumidifying, starting cooling effectively inhibits the battery pack The phenomenon that cabinet generates condensation because of quenching.Since in the case where gas humidity is constant, temperature is lower, the possibility of condensation is formed Property is bigger.Therefore when the temperature and higher humidity of the battery pack box house, the battery pack device starting cooling, without Starting dehumidifying so that the temperature decrease of the battery pack box house, the battery pack box house formed the risk of condensation compared with Greatly.In the embodiment of the present application, before the starting of battery pack device is cooling, first starting dehumidifying, reduces the battery pack cabinet Internal temperature and humidity, avoids the air of high humility and the phenomenon that condensation occurs to the cold, to inhibit the battery pack Box house generates the phenomenon that condensation.

In one implementation, first object value is preset temperature value, and the second target value is default humidity value.

When the temperature of the battery pack box house is greater than or equal to preset temperature value, show in the battery pack cabinet The temperature in portion is higher, and the battery pack for being unfavorable for the battery pack box house works normally, and is needed at this time to the battery Packet cools down, and guarantees the normal work of the battery pack, improves the reliability of the battery pack device.And work as the battery The temperature of packet box house is greater than the temperature outside the battery pack cabinet, and the battery pack device is not necessarily required to the electricity Chi Bao cools down, and therefore, in this embodiment, first object value uses preset temperature value.

And default humidity value is the corresponding relative humidity of preset temperature value, the second target value is default humidity value at this time, is made It is more accurate to obtain the judgement whether the battery pack device may generate dew condensation phenomenon to the battery pack box house, thus So that the battery pack device more effectively inhibits the dew condensation phenomenon of the battery pack box house.

In the embodiment of the present application, when the battery pack device judges that the temperature value of the battery pack box house is greater than Or when being equal to default humidity value, and when the humidity value of the battery pack box house is greater than or equal to default humidity value, the control Device processed not only needs to open cooling-part and cools down to the battery pack box house, and be also required to open dehumidifying section with Inhibit the phenomenon that condensation occurs for the battery pack cabinet.If the controller directly opens cooling-part, the battery lodge A possibility that high temperature and humidity gas in internal portion meets quenching, and dew condensation phenomenon occurs for the battery pack box house at this time is very big.

At this point, the first object value can be the temperature value outside the battery pack cabinet.The first object value It can be the preset temperature value.Second target value can be the humidity value outside the battery pack cabinet.Described second Target value also can be the default humidity value.

When the controller judges that the temperature value of the battery pack box house is less than outside the battery pack cabinet When temperature value, if dehumidifying section is in the open state, the high-temperature gas outside the battery pack cabinet enters to the institute compared with low temperature Battery pack box house is stated, and high-temperature gas enters compared with the easy condensation of the battery pack box house of low temperature, therefore the electricity at this time Pond bag apparatus stops dehumidifying, avoids high-temperature gas outside the battery pack cabinet and enters the battery pack cabinet compared with low temperature Inside, to inhibit the phenomenon that the battery pack cabinet generates condensation.Also can at this point, closing the battery pack device and stopping dehumidifying Enough play the role of energy saving.And since temperature is higher, the saturated steam content in air is higher.Therefore, when described When the temperature value of battery pack box house is less than the temperature value outside cabinet, the water content of the battery pack box house air can Can be smaller than the water content of cabinet outside air, the battery pack device stops dehumidifying at this time, and the battery pack cabinet is avoided to draw Enter the higher gas of water content, to inhibit the phenomenon that the battery pack cabinet generates condensation.

When the controller judges the temperature value of the battery pack box house less than preset temperature value, show described The temperature of battery pack box house is lower, and the heat that the battery pack of the battery pack box house generates at this time can make the battery The temperature of packet box house continues to increase, during the battery pack box interior temperature is raised, in the battery pack cabinet A possibility that portion's generation dew condensation phenomenon, is minimum, can ignore, therefore reaches the mesh of energy saving then without starting dehumidifying at this time 's.

Wherein, when the controller judges the temperature value of the battery pack box house less than preset temperature value, table The temperature of the bright battery pack box house is lower, and the temperature of the battery pack box house is not up to cooling requirement, at this time institute The battery pack for stating battery pack box house works under control environment state, and the battery pack device can also stop at this time It is cooling, energy saving can be played the role of.

When the controller judges the humidity value of the battery pack box house less than the second target value, the battery Water content outside lodge body is higher than the water content of the battery pack box house, and the battery pack device stops dehumidifying at this time, The inside that the relatively high gas of the water content outside the battery pack cabinet is introduced to the battery pack cabinet is avoided, thus Inhibit the phenomenon that the battery pack cabinet generates condensation.

In one embodiment, after battery pack device starting is cooling, the method also includes:

The battery pack device confirms the temperature value of the battery pack box house；

When the temperature value of the battery pack box house is less than preset temperature value, the battery pack device stops cooling.

In the embodiment of the present application, when the temperature value of the battery pack box house is less than preset temperature, show described The temperature of battery pack box house is lower, and the temperature of the battery pack box house is not up to cooling requirement, at this time the battery The battery pack of packet box house works under control environment state, and the battery pack device stops cooling, Neng Gouqi at this time To the effect of energy saving.At this point, the humidity value of the battery pack box house can be greater than or equal to first object value, also can Enough it is less than first object value.Namely in the embodiment of the present application, as long as the temperature value when the battery pack box house is less than in advance If when temperature, the battery pack device stops cooling, the battery pack device is avoided to flog a dead horse and result in waste of resources.

In one embodiment, the first object value is the temperature value outside the battery pack cabinet, and described the Two target values are the humidity value outside the battery pack cabinet.
