A battery device for a motor vehicle, having a first battery module with a first housing, a second battery module which is arranged next to the first battery module in a first direction (X) with a second housing, a coolant channel, and a battery module connector arranged in the coolant channel for electrically contacting the first and the second battery module. The first and the second housing have coolant inlet openings on respective opposite end sides in a second direction (Y) arranged orthogonally to the first direction (X). In each case one coolant outlet opening is arranged in the center of the first or second housing with respect to the second direction (Y) and leads into the coolant channel.

An apparatus for electrically and mechanically coupling battery modules to an electric vehicle includes an interface plate and one or more battery trays. The interface plate includes an electrical output that electrically couples the interface plate to the vehicle. The interface plate also includes an electrical input that is electrically coupled to the electrical output. The battery tray is configured to receive a plurality of replaceable battery modules and is releasably mechanically coupled to the interface plate.

An all-solid-state battery that includes a battery element and an exterior material covering a surface of the battery element, wherein the exterior material includes one or more glass state materials and one or more crystalline state materials.

A hybrid power train structure for off-road vehicles (ATVs, UTVs and SSVs) uses an internal combustion engine (“ICE”) rotating a crankshaft through a continuously variable transmission (“CVT”) as a primary source of locomotion torque, but also includes a driving/generator motor which, in certain established conditions, can either provide an additional or alternative source of locomotion torque or can harvest electricity from the torque created by the internal combustion engine. The driving/generator motor is an axial flux motor of small size for its relative torque output, which can either be directly coupled to the CVT output shaft or, when additionally used as a starter motor for the ICE in an automatic ICE starting and stopping routine.

An under body may include a side sill inside front panel bent similar to the side sill inside panel to connect a front end portion of the side sill inside panel with a dash panel to be bonded to each other; a front side member connecting member connected with a bottom surface of the dash panel and a rear end portion of a front side member while being bonded to an inside surface of the side sill inside front panel; a side sill inside rear panel configured to connect a rear end portion of the side sill inside panel with a rear side member to be bonded to each other; and a rear side member connecting member configured to connect a bottom end portion of the side sill inside rear panel with a front inside surface of a rear side member to be bonded to each other.

A power conversion device includes a main battery, an auxiliary battery, an inverter circuit, a high-voltage wiring, a smoothing capacitor, a main wiring, a subsidiary wiring, a DC-DC converter and a controller. The DC-DC converter is connected to a high-potential wire of the main wiring, a low-potential wire of the main wiring, a high-potential wire of the subsidiary wiring, a low-potential wire of the subsidiary wiring, the high-potential wire of the high-voltage wiring and the low-potential wire of the high-voltage wiring. The controller is connected to the auxiliary battery and the DC-DC converter. The DC-DC converter is configured to supply a power stored in the smoothing capacitor to the controller through the DC-DC converter such that the controller drives the inverter circuit and that the power stored in the smoothing capacitor is supplied to the motor through the inverter circuit, when a collision of the vehicle is detected.

The present invention provides a battery control system for controlling a battery pack that is formed by a plurality of battery cells. The battery control system comprises: a detecting circuit for detecting at least one operation parameter of the battery pack; an activating circuit, which receives the at least one operation parameter from the detecting circuit, for generating a first control signal when the detected at least one operation parameter exceeds or is below at least one critical-level threshold; a supervision unit, which receives the at least one operation parameter from the detecting circuit, for managing the battery pack and generating a second control signal when the at least one operational parameter exceeds or below at least one cap-level threshold; a switching circuit, which receives the first control signal from the activating circuit and/or the second control signal from the supervision unit, for connecting the battery pack to and disconnecting the battery pack from an power output in response to the first control signal and/or the second control signal.

A system and method for controlling a vehicle powertrain including an engine and a motor operable to propel the vehicle includes reducing a torque of the motor at a first torque reduction rate from a torque level above a minimum motor torque in response to a deceleration request.
