A concrete mixer truck includes a chassis, a plurality of tractive assemblies coupled to the chassis, a mixing drum rotatably coupled to the chassis, the mixing drum defining an internal volume configured to contain material and an aperture through which the material can enter and exit the internal volume, an energy storage device positioned at a rear end of the chassis and configured to provide electrical energy, and an electromagnetic device electrically coupled to the energy storage device, where the electromagnetic device is configured to receive the electrical energy from the energy storage device and provide mechanical energy to drive at least one of the plurality of tractive assemblies to propel the concrete mixer truck.

A concrete mixer vehicle includes a chassis, a tractive assembly coupled to the chassis and configured to propel the concrete mixer vehicle, a mixing drum rotatably coupled to the chassis, and an electromagnetic device configured to convert electrical energy to mechanical energy to drive the tractive assembly. In a first configuration, a first battery module is removably coupled to the chassis and configured to provide the electrical energy to the electromagnetic device, and in a second configuration, the first battery module is removed from the chassis and replaced with a second battery module, the second battery module removably coupled to the chassis and configured to provide the electrical energy to the electromagnetic device.

An interchange energy device for an electric vehicle enables an electric vehicle to be compatible with existing power lines such as overhead catenary system with little to no modification necessary to a modern electric vehicle. The interchangeable energy device has the same form factor as a battery pack, and is fully compatible with the drive system of the vehicle. The interchangeable device enables a battery pack to be swapped for an adapter to take advantage of existing power systems such as an overhead catenary system.

The present invention provides a traveling device including: a framework member of a vehicle body; at least one rail member being supported by the framework member and extending substantially horizontally; a battery supporting member that is mounted to be insertable into the vehicle body and extractable from the vehicle body by the rail member for supporting a battery; and at least one damper member being disposed between the rail member and the battery supporting member, wherein the damper member is attached above or below the rail member.

Systems and methods for implementing a battery swapping system for an electrically powered vehicle. The vehicle includes a propulsion system, a first battery powering the propulsion system, and another power source powering the propulsion system. The vehicle further includes a controller configured to enable unloading the first battery to a first charging station by propulsion of the vehicle towards and then away from the first charging station. The controller is further configured to subsequently enable loading a second battery from a second charging station by propulsion of the vehicle powered by the another power source towards the second charging station.

A modular battery system for use with a material handling vehicle, the modular battery system comprises a battery assembly and a counterweight assembly. The battery assembly can include a power source and a battery base, and the counterweight assembly can include a counterweight base configured to slidably receive the battery base and be removably secured thereto.

An electrical vehicle including a vehicle body, a passenger compartment, a chassis supporting the passenger compartment, a plurality of wheels and at least one electrical motor for driving the wheels. A battery compartment of the vehicle is configured to removably mount therein a plurality of more than two rechargeable batteries which are movable into position in the battery compartment by a battery conveyor system which has a battery access opening through which batteries are installed or removed, one by one, to and from the battery compartment. In the battery compartment, a connection mechanism effects the needed mechanical and electrical connections. An overall control system controls the conveyor system and the connection mechanism to enable rapid replacement of the removable batteries, whereby an electrical vehicle can be instantly driven, even after its batteries have been discharged by a replacement of the discharged batteries and the installation of freshly charged batteries.

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.
