The invention relates to a chassis arrangement for an electrified heavy vehicle, the chassis arrangement comprising a chassis frame with at least one rail extending in a longitudinal direction of the chassis arrangement; at least one battery module for propulsion of the heavy vehicle; and a battery module support arrangement including a rail attachment part attached to the rail, and a battery module attachment part attached to the battery module, the battery module attachment part being releasably connected to the rail attachment part by a stub connection extending perpendicular to the longitudinal direction of the chassis arrangement.

This application is directed to an apparatus for providing electrical charge to a vehicle. The apparatus comprises a driven mass, a generator, a charger, a hardware controller, and a communication circuit. The driven mass rotates in response to a kinetic energy of the vehicle and is coupled to a shaft such that rotation of the driven mass causes the shaft to rotate. The driven mass exists in one of (1) an extended position and (2) a retracted position. The generator generates an electrical output based on a mechanical input coupled to the shaft such that rotation of the shaft causes the mechanical input to rotate. The charger is electrically coupled to the generator and: receives the electrical output, generates a charge output based on the electrical output, and conveys the charge output to the vehicle. The controller controls whether the driven mass is in the extended position or the retracted position in response to a signal received from the communication circuit.

A battery pack locking mechanism, provided on a side wall of a bracket, used for unlocking or locking a battery pack on the bracket, and comprising a fixing portion. The fixing portion has a locking space. When the battery pack is placed relative to the bracket, the locking mechanism is used for locking a connecting portion on the battery pack in the locking space. On one side of the locking space, the locking mechanism is provided with an opening facing towards the battery pack and entering the bracket along the horizontal direction, so that the connecting portion enters the opening along the horizontal direction and moves into the locking space. According to the locking mechanism, effectively reducing the complexity of the process and the step of mounting and fixing the battery pack on the bracket. Also provided are a bracket assembly, an electric vehicle, and a battery pack locking method.

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 removable battery fixing assembly of an electric vehicle includes a removable battery module and a fixing device installed in the electric vehicle. The removable battery module has a main body with first and second side surfaces. A guiding bar is disposed on the first side surface. The fixing device includes a base, a driving part, a main transmission part, a guiding part, a first stopping part, and a second stopping part. When installing the removable battery module, the guiding bar is aligned with and moved along the guiding part. When moving the removable battery module to a specified position, the driving part drives the main transmission part horizontally, so that the first stopping part is correspondingly rotated to urge against an end part of the guiding bar. Meanwhile, the plural connection elements correspondingly drive the second stopping part to lock the second side surface of the removable battery module.
