Abstract

The embodiment of the invention discloses an intelligent charging method. The method comprises the steps of obtaining current battery cell surface temperature as initial temperature when it is determined that communication with a charging device is successful; obtaining the battery cell surface temperature according to the set detection period, determining a plurality of first target temperaturevalues within the current temperature rise period corresponding to the current detection period, and a plurality of second target temperature values within the prior temperature rise period adjacent to the current temperature rise period, and determining the average value obtained by removing the maximum value and the minimum value from the first target temperature values and the second target temperature values as the real-time battery cell surface temperature corresponding to current temperature rise period and the reference battery cell surface temperature corresponding to the prior temperature rise period; when the initial environment temperature relative to the battery cell surface temperature is higher than a preset value, determining whether the temperature rise rate is higher thana temperature rise threshold value or not according to the real-time battery cell surface temperature and the reference battery cell surface temperature; if the temperature rise rate is higher than the temperature rise threshold value, sending a request for reducing current output current to the charging device.

Description

technical field [0001] The invention relates to the field of intelligent charging, in particular to an intelligent charging method, a rechargeable battery, a charging system and a computer storage medium. Background technique [0002] With the increasingly intensified contradiction between economic development, energy supply, and environmental pollution, energy conservation and loss and reduction of dependence on fossil fuels have become urgent problems to be solved. Electric vehicles are favored by countries all over the world because of their fuel-saving, environmental protection, and high-efficiency characteristics. The increase in electric vehicles requires the development of rechargeable batteries and charging technologies. [0003] At present, most of the storage batteries on the market are charged by the corresponding charging device, and after the charging device is connected to the battery, it will continue to charge the battery with a constant output current, and t...
