An electrically powered truck and system for charging or easily changing the internal rechargeable battery. The truck has an internal rechargeable electric battery which is exposed when a hatch on the truck is opened. The replacement rechargeable battery is inserted into the holding frame once the original rechargeable battery has been removed. The new rechargeable battery is then secured within the truck.

An electric vehicle backup battery is provided. The back up battery is removably positionable within an interior or the vehicle and can operate to directly power the vehicle, or charge a primary battery of the vehicle, if and when the primary battery runs out of charge, to allow the electric vehicle to reach a charging source.

Landing apparatuses for unmanned aerial vehicles are provided herein. An example battery assembly can include a housing having a top surface, and a bottom surface, wherein the bottom surface of the housing having a receiving interface that receives a first protruding adapter of an associated object. The top surface of the housing having a second protruding adapter that mates with the receiving interface of a second battery assembly, an energy storage unit disposed within the housing, a locking mechanism disposed within the housing, a biasing member that places the locking mechanism in a locked configuration, and a controller having a processor and memory for storing instructions, the processor being configured to execute the instructions to cause the locking mechanism to move into an unlocked configuration.

A mechanical stabilization system for a battery assembly is disclosed. The system includes an actuator and a stabilizer that are configured to work in concert. The actuator and stabilizer are disposed in a housing of the battery assembly. The system may be implemented by depression of the actuator disposed in the housing, which causes the stabilizer to retract a support post into the housing. The depression can occur during a docking operation of the battery assembly with a lift mechanism for an electric vehicle. When the actuator is released, the support post automatically reverts to its previous, deployed state. The support post is configured to maintain the battery assembly in a stable configuration when the battery assembly is separated from the electric vehicle.

An electric work vehicle includes an electric work machine including a battery mounting unit on which a battery is detachably mountable; a battery housing unit supported by at least one wheel and configured to house the battery; and a battery carrier including the at least one wheel and a manual push handle configured to be manually pushed to move the battery housing unit. The battery housing unit is detachably mountable on the battery mounting unit for the battery to be mounted on the battery mounting unit, and the at least one wheel and the manual push handle are separable from the battery housing unit.

A vehicle attachment structure includes: a fixing member paired up with at least part of one component out of the first component and the second component, the fixing member being configured to fix at least part of the other component out of the first component and the second component and release the fixation; and a coupled member placed in the one component at a position corresponding to the fixing member, the coupled member being made of a magnetic material. The fixing member includes a magnet placed at a position corresponding to the coupled member, and a connecting mechanism connected to the magnet and configured to turn or rock the magnet so that the magnet approaches or separates from the coupled member.

A Universal Battery Pack (UBP), electric vehicle powertrain design and battery swapping network with battery health management enabling a user of an electric vehicle to access data such as state of health monitoring to enable advanced interface with the electricity grid to address challenges in the adoption of electric vehicles which include cost, range anxiety, charging time and infrastructure, and impacts of vehicle to grid (V2G) operations. The electric vehicle powertrain design is equipped with swapping capability, the modular swappable battery packs, battery storage apparatus, and the bidirectional charging systems. The present invention discloses a method for monitoring, assessing and controlling the battery pack and charger, and the communication interface between the systems and the electricity grid and across the battery swapping network. The present invention provides a cost-effective way of adopting electrification, reducing strain on the electricity grid during peak periods and extending the life of electric vehicle batteries.
