Abstract: A battery charging method includes: determining whether a present charging cycle satisfies a floating charging condition when a first condition is satisfied, the first condition being that in a case where battery capacity is greater than a set capacity, a duration of continuous charging is greater than a set threshold; and charging using a set floating charging mode after determining that the present charging cycle satisfies the floating charging condition. As such, the battery capacity during the charging process is detected in real time. In a case where the battery capacity is greater than the set capacity, the duration of continuous charging is greater than the set threshold and the present charging cycle satisfies the floating charging condition, the floating charging mode is used in time, such that batteries are prevented from dangerous situations such as bulging, expansion and explosion, and the safety of battery charging is improved.

Abstract: The present disclosure discloses a device and a method for forming a metal plate by using a high-energy electric pulse to drive an energetic material. The device includes high-energy pulse discharge equipment, an intelligent robot arm control system, a vacuum pumping device, a hydraulic press, a forming die, positive and negative electrodes, an energetic rod, and liquid supply equipment. According to the present disclosure, energy of a metal wire is added to energy of an energetic material after energy release to implement high-rate forming of the plate. A discharge voltage of the high-energy pulse discharge equipment is reduced and a service life thereof is prolonged. The discharge equipment is triggered by the manufactured small-size electric pulse metal wire, thereby reducing a volume and costs of the equipment and miniaturizing the equipment to implement precise operating, forming, and intelligent integration with the robot arm control system.
