The fuel cell system includes a fuel cell arranged to receive ambient air at a cathode inlet, and a tank arrangement fluidly connectable to the cathode inlet. The fuel cell system is configured to supply oxygen based fluid from the tank arrangement when a toxic substance level of the ambient environment is above the predetermined threshold limit.

A mounting system for mounting of an energy storage system to a frame of a vehicle. The mounting system comprises an energy storage system bracket assembly, a frame-mounted bracket assembly and a locking mechanism comprising a sliding lock assembly translatable between an open and a closed position locking the energy storage system.

An alarm system for detecting a gas leakage from a vehicle is provided. The alarm system includes a control unit and one or more gas leakage sensors configured to be temporarily arranged on or at the vehicle. The control unit is arranged to obtain information indicating locations of the one or more gas leakage sensors while temporarily arranged on or at the vehicle. The control unit is also arranged to identify, upon generate a warning alert signal in the alarm system, the location of a gas leakage sensor based on the obtained information as the gas leakage sensor detects a gas leakage.

A zero-emission configurable medium/heavy duty class electric truck is disclosed that uses high-voltage, battery-powered electrical energy for both motive power and auxiliary powered unit power. In embodiments, the electric truck includes a central frame having a pair of main frame rails configured to support at least two battery modules, a front subframe configured to support a front axle assembly and a cab, and a rear subframe configured to support at least one rear axle assembly and a rear payload module selected from one of the set of multiple configurable rear payload modules. In embodiments, at least one of the front axle assembly and the rear axle assembly include an electric motive motor powered by a battery management system configured to manage generation and distribution of alternating-current (AC) electrical power from the at least two battery modules to the at least one electric motive motor to provide motive power to the zero-emission configurable electric truck and to at least one auxiliary power unit (APU) to provide auxiliary power to the rear payload module.

A refuse vehicle including a chassis, a body assembly coupled to the chassis, the body assembly defining a refuse compartment, an electric energy system, an auxiliary power system comprising a reservoir to hold a hydraulic fluid, and a hydraulic pump powered by an electric motor, wherein the electric motor is powered by the electric energy system and the hydraulic pump pressurizes the hydraulic fluid to power one or more actuators, and wherein a prime mover of the refuse vehicle charges the electric energy system. The one or more actuators include a packer actuator configured to compact refuse in the refuse compartment

Vehicle to project concrete, including a truck provided with a main motor to move the truck using a movement unit, a unit to project the concrete equipped with a pumping device configured to feed the concrete along a pipe, where the vehicle includes a unit to generate and feed electric energy configured to selectively feed one or more of either the movement unit of the truck, the concrete projection unit and the pumping device.

A charging amount calculation apparatus calculates an amount of power consumption by a battery for running along a running route and a during-running charging amount received by a power reception apparatus from at least one second power feeding facility. The charging amount calculation apparatus calculates a pre-running charging amount based on the amount of power consumption and the during-running charging amount.

A modular electric vehicle system, allowing for the assembly of many different vehicle configurations using a plurality of interchangeable vehicle assembly modules, including at least two powered vehicle assembly modules in an assembled vehicle each of which has self-contained drive and power systems and controls which can be connected together by a central network bus on the vehicle. At least one of the powered vehicle assembly modules will be a steering module, with the necessary additional controls and components to steer the axle thereon and in turn steer the assembled vehicle. The connection of the network bus and the modules would be done in an interchangeable way so that different modules could be interchangeably placed in the assembled vehicle. Various steering systems, control methodologies and vehicle attachments are also disclosed.

Disclosed is an extended-range full-electric low-speed tractor, which includes a system control unit, a battery pack, a frequency conversion driver, a bidirectional DC-DC converter, a generating set and a drive system. The generating set is capable of working in an intermittent mode. The generating set will be started when the power of the battery pack is lower than a preset working range; once the generating set begins to work, the generating set will be running under a condition of “the most economic fuel consumption” and provide stable output at constant speed and constant power, so as to make sure that the generating set is not overloaded, emits no black smoke and has highest energy efficiency. It has advantages of low energy consumption, low pollution and long life of the generating set.

A vehicle having at least one cargo pod. The cargo pod may be rolled into and out of a cargo area of the vehicle. The cargo pod may include at least one battery. The battery may be selectively connectable to a vehicle power network. The battery may be disposed proximate a base of the cargo pod.
