Problems solved by technology

The traditional emergency lights are discharged through their own charging and discharging batteries, so that the lighting device of the emergency lights continues to illuminate. The effective charging and discharging temperature of the traditional charging and discharging batteries needs to be greater than minus 30 degrees, and when the ambient temperature is extremely low, the battery If the temperature is lower than this temperature, it will be almost impossible to charge and discharge due to the loss of activity of the electrolyte, making the charge and discharge battery unable to work normally.

Embodiment Construction

[0017] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0018] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ...

Abstract

The present invention relates to a battery temperature control method and a battery temperature control circuit. The battery temperature control method includes acquiring a first detection signal corresponding to the ambient temperature; detecting whether the first detection signal matches a first preset signal; When the first preset signal matches, obtain a second detection signal corresponding to the battery temperature; detect whether the second detection signal matches the second preset signal; when the second detection signal matches the second preset signal, turn on the heating circuit. Detect the match between the first detection signal and the first preset signal. When the first detection signal matches the first preset signal, it indicates that the ambient temperature is low. At this time, continue to detect the match between the second detection signal and the second preset signal. In case of matching, when the second detection signal matches the second preset signal, it indicates that the temperature of the battery is low, and the heating circuit is turned on to heat the battery, so that the temperature of the battery rises, ensuring normal charging and discharging of the battery in a low temperature environment.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery temperature control method and a battery temperature control circuit. Background technique [0002] With the improvement of people's living standards, in the case of power outages, emergency lights are used as lighting tools for emergency lighting or emergency power supply places. Traditional emergency lights are discharged through their own charging and discharging batteries, so that the lighting device of the emergency lights continues to illuminate. The effective charging and discharging temperature of traditional charging and discharging batteries needs to be greater than minus 30 degrees. In the case of extremely low ambient temperature, the battery If the temperature is lower than this temperature, it will be almost impossible to charge and discharge due to the loss of activity of the electrolyte, making the rechargeable battery unable to work normally. Conten...
