Embodiment Construction

[0029] It should be noted that, in the case of no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0030] The invention is aimed at the heating and heat preservation of the battery of the fuel cell vehicle after the charging of the whole vehicle is completed. Wherein, although the prior art discloses the heating and heat preservation of the battery, the prior art does not perform the above operations after the charging of the whole vehicle is completed, and the prior art utilizes the electric energy of the battery of the vehicle, so It will shorten the cruising range of the vehicle. The technical solutions of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] figure 1 It is a schematic flowchart of a vehicle battery heat preservation method according to an embodiment of the present invention. Such as figure 1 As shown, the batte...

Abstract

The invention relates to the field of vehicle batteries, and provides a vehicle battery heat preservation method and system. The vehicle battery heat preservation method comprises the steps that in response to complete vehicle charging, whether the current temperature of a vehicle battery is smaller than a preset temperature threshold value of the battery is detected; wherein the temperature threshold is configured to be the lowest temperature value at which the battery can maintain normal performance; and when the detection result is yes, the vehicle is controlled to obtain electric energy from external charging equipment so as to heat the battery, so that the battery is heated to be above the temperature threshold value, and heat preservation of the battery is completed. According to the vehicle battery heat preservation method, the battery can be heated under the condition that the electric quantity of the battery used for vehicle endurance is not consumed when the battery is charged.

Description

technical field [0001] The invention relates to the technical field of vehicle batteries, in particular to a vehicle battery heat preservation method and system. Background technique [0002] Fuel cell vehicles generally provide driving energy through fuel cells and power batteries. Whether it is a fuel cell or a power battery, its working performance is related to its own temperature. When its temperature is low, its working performance will be deteriorated. [0003] At present, after the power battery of the vehicle is fully charged, the vehicle will automatically power off and go to sleep. If the fuel cell or power battery continues to be in a low temperature environment after the vehicle is powered off and goes to sleep, the fuel cell or power battery will also be shut down by the low temperature. The temperature of the vehicle itself is too low due to environmental influences. At this time, if the vehicle is started, in order to ensure that the fuel cell or power batte...
