Abstract

The invention is applicable to the technical field of lithium batteries and provides a control method of a lithium battery auxiliary heating system. The control method comprises the following steps ofmonitoring the battery temperature of a lithium battery, when the battery temperature meets a preset condition, obtaining solar energy input power; and controlling an auxiliary heating system according to the solar energy input power. According to the control method, the auxiliary heating system is controlled by integrating the two factors of the battery temperature and the solar input power, a problem that the lithium battery cannot work in a low-temperature state is solved, and the solar power supply system can efficiently play a role in a low-temperature environment.

Description

technical field [0001] The application belongs to the technical field of lithium batteries, and in particular relates to a control method and equipment for a lithium battery auxiliary heating system. Background technique [0002] Due to its material characteristics, lithium batteries need to be charged and discharged within a certain temperature range. When the current temperature is lower than a certain temperature, the lithium battery cannot be charged and can only be discharged; when the current temperature is lower, the lithium battery It cannot be charged, nor can it be discharged. For example, the allowable temperature range for charging of a general lithium battery is 0°C to 45°C, and the allowable temperature range for discharge is -20°C to 60°C. The lithium battery of ordinary solar-powered equipment cannot be charged below 0°C, but can only be discharged; it cannot be discharged below -20°C, that is, it cannot be charged or discharged, which is equivalent to being...
