The embodiment of the invention provides a charging control method and device, a charger and a computer readable storage medium, and relates to the field of charging control. After the charger is successfully connected with an intelligent battery, a charging over-current threshold value of the intelligent battery is obtained, an initial output current value of the charger is set according to the charging over-current threshold value, and the intelligent battery is charged according to the initial output current value, thereby avoiding the charging over-current of the intelligent battery at thebeginning of charging; in the charging process, through the obtaining of a real-time charging current value collected by the intelligent battery, if the real-time charging current value is less thanthe reference current value, a first preset current value is increased on the basis of the initial output current value, and a new output current value is obtained and used as the initial output current value to charge the intelligent battery, so the initial output current value set by the charger is continuously adjusted in the charging process, and therefore, the intelligent battery is charged with the charging current close to the charging over-current threshold value, and the charging current is controlled within the charging over-current threshold value.
Description
Technical field [0001] The present invention relates to the field of charging control, and in particular to a charging control method, device, charger and computer-readable storage medium. Background technique [0002] In a battery management system (Battery Management System, BMS), in order to fully charge the smart battery at the fastest speed, the charger will charge the smart battery with a charging current close to the charging overcurrent threshold of the smart battery. [0003] Since the current sampling of the charger and the current sampling of the smart battery have a certain deviation, if the current sampling of the charger is too small or the current sampled by the smart battery is too large, the charging current of the smart battery will easily exceed the charging overcurrent threshold, which will lead to the smart battery. Start charging protection and interrupt charging. Summary of the invention [0004] In view of this, the purpose of the present invention is to pro...
