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 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.

An electric work vehicle includes a vehicle body having traveling wheels, a traveling motor capable of driving the traveling wheels, and a battery unit having, at one end portion thereof, a pair of left and right leg wheels, the battery unit being detachably attachable to a battery storage section of the vehicle body and being capable of supplying electric power to the traveling motor. The battery unit, when detached from the battery storage section, is posture-switchable between a flat placement state in which the leg wheels and the other end portion thereof opposite to the side on which the leg wheels are located are placed in contact with the ground surface and a tilted posture in which the battery unit can stand on its own with the other end portion thereof being located higher than the leg wheels.

An electric work vehicle includes: a carrier 32 in which a battery can be stored and a support portion 40 is provided; a carrier storage portion provided in a vehicle body and capable of holding the carrier 32; a guide portion 21, 22 that is capable of supporting, via the support portion 40, the carrier 32 operated so as to be lifted from the ground, in a state in which the carrier is lifted from the ground, and guiding the carrier 32 toward the carrier storage portion; and a positioning portion 42 configured to, when the carrier 32 placed on the ground is operated so as to be lifted and the support portion 40 has reached a position at which the support portion 40 can be supported by the guide portion 21, 22, stop the operation of lifting the carrier 32.

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 battery mounting mechanism that allows for one or more battery assemblies to be mounted in various positions within a vehicle via a securely attached mounting assembly that may allow for quick and easy adjustment of the position of the battery assemblies while further preventing rotation of the battery assemblies. Further provided herein is a mechanism for connecting multiple battery assemblies into a single battery unit while still allowing these battery assemblies to take advantage of the battery mounting mechanism provided herein.

This invention relates to a rechargeable battery system. The invention, particularly relates to a battery system that comprises at least one battery pack and a network of charging stations. The battery pack is typically provided in cars, and other all other modalities of transport including vans, trucks, buses, trains, ships, planes, etc. The charging stations are provided at strategic locations for ease and convenience. The user of the vehicle can either visit the charging stations or Mobile charging stations can come to a particular location where the customer determines by use of a special Apps (mobile or web-based) to either replace the discharged battery packs with fully charged battery packs, or the user can recharge the battery packs at the charging stations. The battery packs can have different ratings, but the outer casing of the battery packs of different rating will have a standard size, which provides the battery packs a modular configuration. The racks that holds the battery packs are universal and unique that multitudes of these racks can be mounted any/solar charging stations. Similarly multitudes of racks can be mounted to any vehicle as per the needs of the vehicles. The batteries are designed in such a unique way that it is easy for anyone or a robot to change the batteries. This make the battery exchange program unique and stand out to other inventions.

An electric work vehicle includes: a battery accommodating portion that is provided in the vehicle body and accommodates a battery; a first connector provided on the battery accommodating portion; a second connector provided on the battery; and an operating tool for moving the battery and the second connector, and switching from a pre-attachment orientation in which the second connector opposes the first connector to an attachment orientation in which the second connector is joined to the first connector.

An electric powered work vehicle is to be configured so that holding of the battery at the storage position can be carried out easily at the time of attachment of the battery. There is provided guide mechanism for movably guiding the battery while supporting it along a horizontal direction between a storage position and a detachment position located away from the storage position along the horizontal direction. There is provided a holding mechanism configured to be automatically operated to a holding state capable of holding the battery at the storage position when the battery is moved to the storage position along the guide mechanism. There is provided a releasing operational portion manually operable to render the holding mechanism to a releasing state for allowing movement of the battery to the detachment position.
