A battery system for electric vehicles is provided. The battery system includes a first battery module, a second battery module configured to accommodate multiple swappable batteries and a switch device. The switch device is configured to switch a first connection configuration between the first battery module and the second battery module, and to switch a second connection configuration between the swappable batteries when switching the first connection configuration. Each of the first connection configuration and the second connection configuration includes a series connection and a parallel connection. In addition, a power control system and a control method of the battery system are also provided.

An energy module exchange system may include an enclosure with one or more storage racks configured to store and charge energy modules; an opening in the enclosure; and a robotic arm configured to retrieve the energy modules from the storage racks and pass them through an opening in the enclosure for exchange with an electric vehicle.

A battery swap apparatus and a battery swap system relating to the field of battery swap for electrical devices is disclosed. The battery swap apparatus includes a floating platform, a locking and unlocking mechanism and an positioning mechanism. The locking and unlocking mechanism is arranged on the floating platform, and the positioning mechanism is arranged on the floating platform. The positioning mechanism includes a positioning member and a driving member. The driving member is configured to drive the positioning member to move in a height direction of the battery swap apparatus, so as to adjust the height of the positioning member. The driving member drives the positioning member to move downwardly to reduce the height of the positioning member The driving member drives the positioning member to move upwardly to increase the height of the positioning member.

A tractor trailer battery system having a battery compartment containing one or more battery units which house one or more battery cells, electrical leads from the battery units to a trailer mounted controller in electrical communication with a cab mounted controller which is in electrical communication an electric motor or hybrid engine system. The battery system allows for either the trailer mounted controller or the cab mounted controller to provide principal communication to the electric motor or hybrid engine system.

The present application describes power tier management for a battery of a light electric vehicle. In examples, a power tier of a battery may have an associated threshold power and time to exert a battery energy over the time of the power tier. Power tiers may be adjusted to lengthen or shorten an overall battery life and remaining battery life of the battery of the light electric vehicle. In an aspect, a processor may control or limit power to specific components and/or functions of the light electric vehicle to stay within or enter a determined power tier. Information may be received and processed by the processor to determine and apply one or more power tiers.

Disclosed is a battery unlocking control method, a battery locking control method and an electric vehicle battery swapping control method. The battery locking control method comprises the following steps: moving the battery to the fixing base to enable the lock shafts to enter the lock slots; after the lock shafts enter the lock slots, detecting the locations of the lock shafts, and moving the battery until the lock shafts arrive at locking locations; and with the lock tongues falling, snapping the lock shafts into the lock slots. By providing various location detection components, the battery is accurately located and locked when being loaded into a fixing base, and then accurately located and unlocked when being removed from the fixing base, thereby achieving full-automatic control during swapping of the battery and improving the swapping speed and success rate of the battery.
