Foldable electrical vehicles and related charging infrastructure are described. The foldable electrical vehicle generally includes three structural members (front and rear wheel-bearing structural members and a seat-bearing structural member) that are pivotally interconnected along their lengths such that they may be pivoted between a closed position wherein the three structural members are disposed roughly parallel to each other in a compact folded configuration, and an open riding configuration wherein an angular relation is formed between the structural members.

A refuse vehicle includes a chassis, a refuse container coupled to the chassis, a tractive assembly coupled to the chassis and configured to propel the refuse vehicle, and an electric energy system configured to provide electrical energy to drive the tractive assembly. In a first configuration, a first energy system is removably coupled to the chassis and configured to provide the electrical energy to the electric energy system and in a second configuration, the first energy system is removed from the chassis and replaced with a second energy system, the second energy system removably coupled to the chassis and configured to provide the electrical energy to the electric energy system.

A storage system for a vehicle has a configuration capable of storing a plurality of high-voltage battery packs in a separably assembled state in a seat backboard of the vehicle through a coupling structure of a protrusion and a groove. Only a broken or failed high-voltage battery pack from among a plurality of high-voltage battery packs assembled to the seat backboard is separated from the seat backboard, and a new high-voltage battery pack can then replace the failed high-voltage battery pack through assembly thereof to the seat backboard at a position from which the failed high-voltage battery pack has been separated.

A refuse vehicle includes a chassis, a refuse container coupled to the chassis, a tractive assembly coupled to the chassis and configured to propel the refuse vehicle, and an electric energy system configured to provide electrical energy to drive the tractive assembly. In a first configuration, a first energy system is removably coupled to the chassis and configured to provide the electrical energy to the electric energy system and in a second configuration, the first energy system is removed from the chassis and replaced with a second energy system, the second energy system removably coupled to the chassis and configured to provide the electrical energy to the electric energy system.

Various personal mobility vehicles, such as scooters, are disclosed. The scooter can include at least one battery and motor for powering at least one driven wheel. The vehicle can include a gear assembly to convert a torque produced by the motor to a different torque to a driven shaft to power the at least one driven wheel. The battery can be removable.

The present disclosure relates to a battery electric dump truck, comprising a frame, a dump body pivotably mounted on the frame, a power unit comprising a battery, the power unit providing electrical energy to at least one electrical propulsion motor of the battery electric dump truck, and a charging interface unit is provided separately from the power unit and connected to the power unit by wiring.

The present disclosure relates to battery electric dump truck comprising a frame, a dump body pivotably mounted on the frame, and a power unit comprising a battery, the power unit providing electrical energy to at least one electrical propulsion motor of the battery electric dump truck, wherein the frame comprises two side beams extending in a longitudinal direction of the battery electric dump truck, and an upper bridge member connecting the two side beams in a lateral direction, the upper bridge member comprising side pillars extending upwards from the side beams and an upper cross beam connecting the side pillars, wherein the power unit extends between the side beams and below the upper cross beam in the longitudinal direction of the battery electric dump truck.

To provide a battery replacement method for determining a suitable frequency of replacing the batteries mounted in a stationary power supply. A battery replacement method for a battery-mounted housing implemented by a computer in which the housing includes: a plurality of mounting spaces that are formed to be alternately stacked in a front side and a rear side of the battery-mounted housing, each of the plurality of mounting spaces having a battery mounted therein; and a take-out port formed in the front side of the battery-mounted housing, the method including: a state acquisition procedure for acquiring an estimated deterioration state of at least one of the plurality of batteries mounted in the battery mounted-housing; and a determining procedure for determining that the battery for which the estimated deterioration state has been acquired be replaced or re-arranged based on the estimated deterioration state and a mounting position of the battery.
