A service robot can detect one or more makers positioned on relative surfaces of a vehicle. Each marker can include data corresponding to its location on the vehicle. The service robot can determine the location of the markers based on the data. The service robot can also determine the location of a service area proximate to the markers. The service robot can receive data generated by the vehicle corresponding to at least one maintenance condition for the vehicle related to the service area. The service robot can select a service to perform on the vehicle based on the at least one maintenance condition. The service robot can be controlled so as to perform the selected service on the vehicle.

The embodiments of the present application provide a method, apparatus, device, and medium for electric energy transmission. The method includes: determining a resource value of a unit of electric energy of a grid at a target time; under a condition that the resource value is greater than or equal to a first resource threshold, determining a number of available batteries in a battery swapping station and an ordered number of batteries in the battery swapping station within a target time period; and under a condition that the number of available batteries is greater than a number of reserved batteries, controlling a charging and discharging module to transmit electric energy of a first battery in the battery swapping station to the grid.

A battery exchange system and a battery exchange method are provided. The battery exchange system includes a plurality of battery exchange stations, a central control station and a handheld electronic device. Each battery exchange station includes a battery exchange device. The battery exchange device includes a battery carrier module. The battery carrier module includes a cabinet and at least one battery storage case disposed in the cabinet. The battery storage case has a storage space for accommodating a fully-charged battery. The fully-charged battery provides a second battery-location information and a battery in-stock information through the corresponding battery exchange station. Accordingly, the battery exchange device transmits the second battery-location information and the battery in-stock information of the fully-charged battery to the central control station, and the handheld electronic device receives a second battery-available information that includes the second battery-location information and the battery in-stock information from the central control station.

Disclosed in the present invention are a battery pack for an electric vehicle, and an electric vehicle comprising same. The battery pack for the electric vehicle comprises: a plurality of battery accommodating areas, which are arranged in a width direction of the electric vehicle, the plurality of battery accommodating areas comprising a middle accommodating area and side accommodating areas, and each battery accommodating area accommodating multiple layers of battery modules; and lock connection structures, which are used for matching locking mechanisms on the electric vehicle so as to lock the battery pack on the electric vehicle, the space in a vertical direction is fully utilized, the accommodating number of the battery modules is increased, the capacity of the battery pack is thus improved, the arrangement of the battery modules is rational, and the size of the battery pack in a horizontal direction is not increased.

Systems and methods for automated swapping of a charged replacement battery for a depleted battery onboard an electric vehicle using a battery delivery vehicle (BDV). The BDV may be configured to operate autonomously or under remote control. The electric vehicle which receives the replacement battery from a BDV may be configured to operate autonomously (e.g., an AGV) or non-autonomously (e.g., an electric passenger car). The BDV is loaded with a fully (or partially) charged battery, and then moved to a rendezvous place at which the BDV is underneath and aligned with the electric vehicle. The battery is uploaded to the electric vehicle while the aligned BDV moves in tandem with the electric vehicle. After the replacement battery has been installed, the power distribution system onboard the electric vehicle switches over to draw DC power from the replacement battery (instead of from a depleted battery) without interrupting vehicle operation.
