Abstract: A method of over-heating protection for a charging apparatus, includes: measuring a charging parameter of the charging apparatus during a charging process, where the charging parameter includes a temperature and a time corresponding to the temperature; estimating a temperature change trend of the charging apparatus based on the charging parameter; and when determining, based on the temperature change trend, that a highest estimated temperature exceeds an upper limit of a preset temperature range, limiting a charging current for the charging apparatus before an estimated temperature exceeds the upper limit of the preset temperature range.
