Abstract: The present disclosure discloses a method and apparatus of managing battery. The method includes: obtaining a first and second state parameters; determining whether a first and second batteries meet a predetermined first paralleling condition, if yes, powering on a current-limiting module, powering on the bidirectional DC/DC converter being and delayingly powering off the current-limiting module; obtaining a third and fourth state parameters; determining whether the first and second batteries meet a predetermined second paralleling condition, if yes, powering on the paralleling switch and delayingly powering off the bidirectional DC/DC converter. The present disclosure can output a voltage under relatively safe conditions and achieve power supply safety.

Abstract: A method of controlling power supply of a caravan including a photovoltaic plate includes: receiving a first power parameter of an input interface element; determining whether there is a mains supply to be input into the input interface element according to the first power parameter; turning on a first switch to make the input interface element be electrically connected to the output interface element if the mains supply is input into the input interface element; receiving a power parameter of a battery pack if the mains supply is not input into the input interface element; determining whether a remaining power of the battery pack exceeds a power threshold according to the power parameter of the battery pack; and making the battery pack be electrically connected to an output interface element if the remaining power of the battery pack exceeds the power threshold.

Abstract: A charging system includes a plurality of mobile power supplies, a plurality of charging units, and a control device. The charging unit includes a fixing device and a charging device, the fixing device being changeable between a locked state where one of the mobile power supplies can be locked in the charging unit by the fixing device and an unlocked state where the one of the mobile power supplies is unlocked from the charging unit. The charging device is configured to charge the mobile power supply fixed in the charging unit. The control device is connected to the charging units, the control device is configured to receive a charging request from a user and generate an unlock command in response to the charging request to control at least one of the fixing devices to switch to the unlocked state.
