The invention provides a temperature detection method, device and equipment of a battery and relates to the technical field of batteries. The method comprises the following steps: comparing a currenttemperature value with an initial temperature base value; and when determining that the current temperature value is greater than the initial temperature base value, a difference value between the current temperature value and a current average temperature value of current time is greater than a pre-set difference value and duration from first time to the current time is less than pre-set duration, acquiring a detection result that the temperature of the battery is raised too rapidly. According to the temperature detection method provided by the invention, when the method determines that the current temperature value is greater than the initial temperature base value, the difference value between the current temperature value and the current average temperature value of the current time isgreater than the pre-set difference value and the duration from the first time to the current time is less than the pre-set duration, the detection result that the temperature of the battery is raised too rapidly is obtained; a temperature raising condition of the battery can be detected only if the initial temperature base value is stored and the current temperature value is continuously updated; and when the temperature is raised too rapidly, the device is overhauled in time, so that the safety of a vehicle is improved and the device does not occupy a great quantity of main chip resources.
Description
technical field [0001] The invention relates to the field of battery technology, in particular to a battery temperature detection method, device and equipment. Background technique [0002] At present, the performance and safety performance of the battery system of electric vehicles are directly related to the temperature. During the use of the battery, many safety problems will be caused by the temperature change; the general detection method for the battery temperature rise is the rolling comparison method, which needs Many temporary variables stored and rolled are compared, the amount of calculation is large, and a lot of resources of the main chip will be occupied. [0003] Therefore, there is an urgent need for a battery temperature detection method, device and equipment that can monitor whether the temperature rise of the battery is too high in real time on the basis of not occupying a large amount of resources of the main chip. Contents of the invention [0004] Em...
