摘要： The present disclosure relates to a charging device. By providing a charge-enabled pin and an engage-enabled pin with different lengths in the charging interface of the charging device, the engage-enabled pin is firstly in contact with a battery when charging. At this time, a charging management circuit controls an LLC half-bridge resonant power supply to soft start. A third end of the charging management circuit outputs a signal to drive a first switch to be turned on, and the output end of the LLC half-bridge resonant power supply charges the battery, and charging soft start and zero-voltage connection are achieved. During the unplugging process, the charge-enabled pin is firstly removed from the battery, and zero-current disconnection can be achieved when unplugging the other pins of the charging interface.

摘要： A battery pack mounting structure and a truck are provided. The battery pack mounting structure includes a connecting member, a clamping plate, a first clamping member, and a second clamping member. The connecting member is configured to load a battery pack. The back plate is connected to the connecting member. The clamping plate is spaced apart from a side of the back plate away from the connecting member. A clamping space configured to accommodate the crossbeam is formed between the clamping plate and the back plate. The first clamping member and the second clamping member that are provided between the clamping plate and the back plate, and configured to fix the crossbeam between the clamping plate and the back plate in a vertical direction.

摘要： The present disclosure relates to an overvoltage protection circuit and a charging device. A voltage applied to a PFC power supply on an input side is collected through an input voltage sampling circuit and an amplifier circuit, and a data processing capability of a charging management circuit is used to determine whether the applied voltage exceeds a preset voltage threshold. The preset voltage threshold refers to a voltage that is not greater than a minimum withstand voltage of an input device of the charger. The power factor correction power supply is controlled to operate to charge the battery to be charged when it is determined that the voltage applied does not exceed the preset voltage threshold, to prevent damage to the input device due to a connection to two phases of voltage.
