A movable battery replacing platform includes a travel-driving portion used for driving the movable battery replacing platform to move on the ground; a lifting portion mounted on the travel-driving portion, for lifting a battery during the replacement of the battery; and a battery mounting portion mounted on the top of the lifting portion, for placing a battery to be replaced or a replaced battery. The battery mounting porting is provided with a battery replacing device. The device can use an unlocking device 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 angle of an upper board 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 remains still.

The present disclosure provides a chassis assembly and a vehicle. The chassis component includes: a chassis provided with a plurality of mounting positions and configured to install a battery module; a quick-release device through which the battery module is installed on the mounting positions, wherein the quick-release device is controlled by a control system; and a voltage electrical connecting assembly electrically connected to the battery module, wherein the voltage electrical connecting assembly is controlled by the control system. The vehicle includes the chassis assembly.

A server includes a communication unit (first communication unit) (second communication unit) that receives information about a request for adjustment of power supply-and-demand in a power grid. The server includes a processor (controller) that predicts a schedule of replacement of a battery (first battery) at a battery station (battery replacement apparatus). The processor specifies, based on the schedule, a battery (second battery) available for charging or discharging for the request for adjustment, and determines, based on the specified battery, whether or not it is possible to respond to the request for adjustment.

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 swappable battery pack is installed on the first EV at the first power supply station, and the first swappable 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 swappable 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 swappable 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.

An unmanned aerial vehicle (UAV) base station includes a housing and a UAV fixation system. The housing includes a top-plate configured for a UAV to land on the top-plate. The UAV fixation system is configured to direct the UAV present on the top-plate to a battery-exchange zone of the top-plate.

Provided are a method and device for estimating the utility of replacement of a battery pack for an electric vehicle, and a charging management method and system based on the method and device. The method comprises the following steps: acquiring state data associated with a first battery pack and a second battery pack, the state data comprising usage history of the first battery pack and performance parameters of the first battery pack and the second battery pack; and determining a utility value according to the state data, wherein the utility value is used to characterize a degree of impact of an operation of replacing the first battery pack with the second battery pack on the service efficiency and service life of a battery pack set to which the first battery pack and the second battery pack belong. The method facilitates improving the service efficiency of a managed battery in a battery swap mode and extending the overall service life thereof.
