Embodiment 1
[0054] Such as figure 1 As shown, the embodiment of the present invention provides a heating control method for a battery pack, and the execution body of the method may be a controller for controlling the power of the heater and the opening value of the water mixing valve. The method specifically may include the following steps:
[0055] In S102, when a heating request for the battery pack is received, the current ambient temperature of the battery pack and the current first power of the heater are acquired.
[0056] Among them, taking the battery pack in electric vehicles as an example, such as figure 2 As shown, the battery pack can be a functional device of an electric vehicle. For example, the battery pack can be a battery pack including a ternary iron-lithium battery cell. Due to the high energy density of the ternary iron-lithium battery cell, lithium ions will be released when the temperature is too low. The precipitation produces lithium crystal dendrites, which may...
Embodiment 2
[0075] Such as image 3 As shown, an embodiment of the present invention provides a heating control method for a battery pack. The execution subject of the method may be a server, and the server may be an independent server or a server cluster composed of multiple servers. The method may specifically be Include the following steps:
[0076] In S302, when a heating request for the battery pack is received, the current ambient temperature of the battery pack and the current first power of the heater are acquired.
[0077] In S304, a target power compensation value, a target opening value, and a target control time corresponding to the ambient temperature and the first power are determined based on the pre-built correspondence.
[0078] Wherein, the corresponding relationship can be the corresponding relationship between the ambient temperature, the first power, the target power compensation value, the target opening value and the target control time determined based on the hist...

[0098] The above is the heating control method of the battery pack provided by the embodiment of the present invention. Based on the same idea, the embodiment of the present invention also provides a heating control device for the battery pack, such as Figure 5 shown.
[0099] The heating control device of the battery pack includes: a first acquisition module 501, a first determination module 502 and a first control module 503, wherein:
[0100] The first obtaining module 501 is configured to obtain the current ambient temperature of the battery pack and the current first power of the heater when a heating request for the battery pack is received;
[0101] The first determination module 502 is configured to determine the target power corresponding to the ambient temperature and the first power, the target opening value of the water mixing valve, and the target control time based on a pre-built corresponding relationship, the corresponding relationship is The corresponding re...
