Abstract

The invention provides a method and a device for determining internal temperature of a battery module and an intelligent terminal, and relates to the technical field of temperature acquisition. The method comprises steps of acquiring the temperature data of a battery module at different charge and discharge rates; constructing a thermal network model of the battery temperature rise according to the temperature data; calculating the parameters of the thermal network model by using a parameter identification algorithm; calculating the internal temperature of the battery module according to the parameters. The method of the invention can effectively improve the accuracy for determining the internal temperature of the battery module.

Description

technical field [0001] The invention relates to the technical field of temperature acquisition, in particular to a method, device and intelligent terminal for determining the internal temperature of a battery module. Background technique [0002] During the use of the battery, the battery temperature will directly affect the performance of the battery, so it is particularly important to determine the battery temperature. For the battery module, it is necessary to determine the temperature inside the battery module in order to more accurately reflect the temperature of the entire battery module. At present, temperature sensors are usually used in the market to collect the temperature of the battery module, but the temperature collected by the temperature sensor is only the surface temperature of the battery module, not the internal temperature of the battery module. The existing method for determining the internal temperature of the battery module will be affected by the bat...
