An electric vehicle may include a battery module, a heat transfer circuit, and a ventilation system. The heat transfer circuit may include a first heat exchanger, a second heat exchanger, and a reversing valve. The first heat exchanger may be adjacent to the battery module and/or in thermal contact with the battery module. The second heat exchanger may exchange heat with an environment external to a cabin of the vehicle. The reversing valve may reverse a fluid flow direction of the heat transfer circuit. The ventilation system may force air across the first heat exchanger or the second heat exchanger and direct the air into the cabin of the vehicle.

An electric vehicle battery pack with a reinforced cover to better support vehicle cabin loads such as seat submerge loads, seat pitch loads, and the like. The cover has a number of reinforcing members affixed thereto and positioned over cross members of the battery pack frame. Loads imposed by the cabin are thus transferred to the reinforcing members and then to the rigid cross members. In this manner, battery packs of embodiments of the disclosure better support cabin loads applied thereto, improving their strength and better protecting more delicate components within the battery pack.

An on-board charging system for an electric vehicle comprising a generator (Dynamo) 1, coupled to the wheel of the electric vehicle. The generator produces a charging voltage which is connected to a 12 V battery, via voltage regular, the 12 V battery, and is connected to the input of a Power Boaster, which boasts the voltage from 12 V at the input to 48 V at the output. A Dual battery isolator is connected between the secondary Lithium battery and the Main lithium battery, that supply power to the a gear drive of the electric vehicle. When there is a drop in the voltage of the main lithium battery, during operation, the intelligent dual battery isolator triggers a release of the stored voltage from the secondary lithium battery pack to instantaneously charge up the main lithium battery, supplying power to the electric vehicle drive.

A battery pack for an electric work vehicle includes: a box-shaped housing; a transport wheel provided to the housing; a transport handle; a bracket fixed to the housing; a swing shaft for swingably connecting the transport handle and the bracket, between a vertical posture in which the transport handle extends upward from the housing and a horizontal posture in which the transport handle lies above the housing; and a vertical socket for receiving a base end part of the transport handle of the vertical posture to resist a torque of the transport handle caused during an operation.

A method for providing a battery arrangement for a motor vehicle, wherein a battery housing arrangement is provided, including a battery housing having at least one holding section for holding a battery module, a cooling device which provides at least part of a housing floor of the battery housing, and an underride guard which is disposed outside the battery housing at the cooling device such that a gap is created between the cooling device and the underride guard, and a viscous heat conducting element and a battery module are placed inside the holding section such that the heat conducting element is located between the underside of the battery module, which faces the cooling device, and the cooling device.

In an electric work vehicle, a power feeding assembly which connects a battery device to a power controller unit so as to feed power includes a fixed connector which is fixed to the battery device and electrically connected to the battery device, a cable harness connected to a power controller unit, and a free connector which is connected to an end of the cable harness and connectable to a fixed connector, and a connecting operation tool is configured to be movable the free connector between the connecting position in which the free connector is connected to the fixed connector and the detaching position.

Powerflow of a rechargeable energy storage system (RESS) is managed according to a method. The RESS has series-connected first and second battery elements with different characteristics. Each element, e.g., a pack, has a corresponding maximum or minimum voltage or current limit. Currents are predicted for each of the first and second battery elements via a controller using a corresponding voltage limit. A requested operating mode of the RESS is used to select a current for the elements. A voltage across the elements is predicted using the selected current and a corresponding battery state space model. The method predicts a total power capability of the RESS over a prediction horizon using the selected current to generate predicted power capability values. The requested operating mode is controlled over the horizon using the power capability values. A powertrain system includes the RESS, an inverter, an electric machine, and the controller.

A busbar for use in mechanically and electrically connecting components in a device or system. The busbar includes a plurality of conductors arranged to provide two opposed end portions and an intermediate portion, wherein each of the conductors has a plurality of intermediate extents that traverse the intermediate portion. The intermediate portion including: (A) an unfused segment where no intermediate extents of the conductors are fused together to form a single consolidated conductor, and (B) a fused segment that includes (i) a partial solidification zone where a majority of the intermediate extents of the conductors are fused together to form a partially solidified region that provides a single consolidated conductor, (ii) a full solidification zone where all of intermediate extents of the conductors are fused together to form a fully solidified region that provides a single consolidated conductor, and (iii) an unsolidified region where all of the intermediate extents of the conductors are not fused together.

A vehicle power conversion apparatus is provided to reduce an overall system size by integrating a motor controller which generates power and a power supply apparatus which converts the power. The vehicle power conversion apparatus includes a driving motor which is connected to an engine and a power converter which selectively converts power in a plurality of modes to generate the power related to an operation of the driving motor. A first battery supplies the power for the conversion or receives the converted power.
