BATTERY CHARGING METHOD, BATTERY CHARGER AND CHARGING ASSEMBLY

A battery charging method includes detecting a battery temperature and a battery power, determining whether the battery temperature satisfies a preset temperature condition for switching charging processes, performing a first charging process when the battery temperature is less than or equal to a first preset temperature value, performing a second charging process when the battery temperature is greater than the first preset temperature value and less than a second preset temperature value, and determining whether the battery power is less than a first preset power value when the battery temperature is equal to or greater than the second preset temperature value and less than a third preset temperature value, and performing a third charging process when the battery power is less than the first preset power value. Pulsed charging and pulsed discharging are alternately performed in the first charging process and a charge current is dynamically adjusted according to the battery temperature and the battery power in the second charging process.
