Disclosed are a movable battery replacing platform (103) and a quick replacing system (100), wherein the movable battery replacing platform (103) comprises: a travel-driving portion (106) used for driving the movable battery replacing platform (103) to move on the ground; a lifting portion (107) mounted on the travel-driving portion (106), for lifting a battery during the replacement of the battery; and a battery mounting portion (108) mounted on the top of the lifting portion (107), for placing a battery to be replaced or a replaced battery, wherein the battery mounting porting (108) is provided with a battery replacing device. The device can use an unlocking device (50) to unlock a battery locked on the bottom of an electric vehicle, automatically aligning an unlocking point of a battery locking mechanism and realizing automatic unlocking in the movement. The whole process is fully automated without manual intervention and can improve battery replacement efficiency. In addition, the angle of an upper board (10) relative to the battery unlocking position can be adjusted by a movement actuating device, so that the unlocking point of the battery can automatically fit where the movable battery replacing platform (103) remains still, so as to further improve unlocking efficiency.

A power maintaining method of electric vehicle includes the following step. In step 01, an energy power is provided by a main battery pack to drive a first electric vehicle (EV) moving to a first power supply station. In step 02, a first swap battery pack is installed on the first EV at the first power supply station, and the first swap battery pack is electrically connected to the main battery pack of the first EV so that the main battery pack is charged by the first swap battery pack. In step 03, the first EV is driven to a second power supply station from the first power supply station. In step 04, the first swap battery pack is uninstalled from the first EV at the second power supply station. In addition, an electric vehicle and a power supply station is disclosed in the present application.

Disclosed is a battery swapping system, comprising a battery swapping device, a signal transmission unit, a position sensor, and a detection section. The battery swapping device comprises a master control unit and a battery pack disassembly and assembly unit. The battery pack disassembly and assembly unit is used for clamping the battery pack, the master control unit is used for controlling the battery pack disassembly and assembly unit to move along a preset path. The position sensor is used for generating a stopping instruction upon sensing of the detection section, sending the stopping instruction to the master control unit which is used for stopping moving the battery pack disassembly and assembly unit according to the stopping instruction. According to the present invention, whether a battery pack is mounted in place can be accurately detected, the accuracy and safety of battery pack swapping is ensured and the costs are low.

Disclosed are a battery replacement device (1″) and a control method therefor. The battery replacement device (1″) is used for mounting a battery on an electric vehicle, and sending a security message to a battery lock (2″) to unlock the battery, so that the battery is electrically connected to the electric vehicle.

Battery swapping includes receiving a swap request for swapping a set of discharged batteries in a vehicle with a set of charged batteries at a charging station. Based on a battery swapping count provided by a user, the set of charged batteries including first and second subsets of charged batteries are selected from a plurality of charged batteries available at the charging station. At least one of a static ID or a dynamic ID is assigned to each charged battery. Each charged battery in the first and second subsets is configured as a master battery and a slave battery by integrating at least the respective static and dynamic ID in a corresponding battery management system of each charged battery, respectively, for facilitating in-vehicle battery communication. Further, the set of charged batteries is released from a charging and storing platform to a swapping platform for swapping.
