A battery for a motor vehicle has a battery housing including at least one busbar and at least two battery cells arranged in the housing and held by a holder. The busbar electrically conductively connects connection points of at least two of the battery cells. In order to achieve an increased power, heat-conducting paths for cooling are provided by virtue of the busbar and/or the holder being thermally conductively connected to the battery housing by a thermal adhesive.

A power supply system includes a first power circuit coupled to a capacity-type first battery and a drive motor, a second power circuit coupled to an output-type second battery, a voltage converter that converts a voltage between the first power circuit and the second power circuit, and a converter ECU and a management ECU that operate the voltage converter to control converter passing power in the voltage converter. The management ECU sets, when a first SOC that is a percentage of charge in the first battery is less than a predetermined lamp-on threshold and a first maximum output P1_lim that is a maximum output of the first battery is more them a predetermined output threshold Pe0 maximum converter passing power Pcnv_max corresponding to maximum power with respect to the converter passing power to 0 to prohibit discharging of the second battery.

A traction battery pack assembly includes, among other things, first and second pieces of an enclosure having an interior area. An attachment rim is disposed at a periphery of the first piece. The attachment rim has a stand-off that includes a platform portion and turned flange. The platform portion extends outward from the interior area in a first direction. The platform portion provides an aperture. The turned flange extends away from the platform portion in a second direction and terminates at an end face. The second direction is transverse to the first direction. The aperture is configured to receive a fastener that clamps the end face against the second piece.

The present disclosure relates to a dual energy storage system that includes a lithium ion battery electrically coupled in parallel with a lead acid battery, where the lithium ion battery and the lead-acid battery are electrically coupled to a vehicle bus, where the lithium ion battery open circuit voltage (OCV) partially matches the lead-acid battery OCV such that the lead-acid battery OCV at 100% of the lead-acid battery state of charge (SOC) is about equal to the lithium ion battery OCV at 50% of the lithium ion battery SOC.

An electric-power conversion apparatus has a heat sink in which one side portion out of a pair of side portions that extend in a direction perpendicular to the axial direction of a motor is formed shorter than the other side portion thereof; a lower case to which the heat sink is fixed is fastened to a driving apparatus through the intermediary of fixing portions at the both end portions of each of the pair of side portions of the heat sink or at respective positions in the vicinity of the both end portions of each of the pair of side portions of the heat sink; at least one of a reactor and capacitors is disproportionately disposed to be closer to said one side portion than to said the other side portion of the heat sink.

A vehicle includes a battery that is mounted as a power source in the vehicle and an instrument panel that displays, to a user of the vehicle, an index (a capacity retention ratio Q or an electric vehicle (EV) travelable distance) indicating a larger value as deterioration of the battery progresses less. The instrument panel displays a maximum value of the index until a predetermined condition has been satisfied.

A battery module includes a housing and a base of the housing. The base includes at least two opposing partition support walls, a first external wall, and a second external wall that is substantially perpendicular to the first external wall. The base also includes two or more partitions extending between the at least two opposing partition support walls to define compartments within the base, wherein each of the two or more partitions extend in alignment with the first external wall and transverse to the second external wall. Further, each of the two or more partitions is coupled to at least one of the at least two opposing partition support walls via a corresponding movable connection configured to be movable between a first position angled away from the first external wall, and a second position angled toward the first external wall.

Some apparatus embodiments include an aircraft having a hybrid parallel electric propulsion system including two internal combustion engines and an electric propulsion system including two electric motors electrically connected to an electric power module. The electric power module is optionally configured for attachment to a bottom side of a fuselage. Each of the electric motors attaches to an aircraft wing outboard of the nearest internal combustion engine. The electric motors and internal combustion engines are operable independently of one another, providing for propulsion by the electric motors during flight and ground operations when the internal combustion engines may operate inefficiently. Some embodiments are implemented as a hybrid parallel electric propulsion retrofit package for adding an electric propulsion system to an aircraft previously equipped only with internal combustion engines.

Presented are electrochemical devices with in-stack sensor arrays, methods for making/using such electrochemical devices, and lithium-class battery cells with stacked electrode assemblies having in-stack sensor arrays. An electrochemical device includes a device housing that stores an electrolyte composition for conducting ions. An electrode stack, which is located inside the device housing in electrochemical contact with the electrolyte, includes at least two working electrodes. An electrically insulating and ionically transmissive separator is interposed between each neighboring pair of working electrodes. A reference electrode is attached to one side of the separator and connected to multiple electrical sensing devices. Multiple electrical sensing leads are attached to another side of the separator, opposite the reference electrode, with each abutting a discrete region of a working electrode and each connecting to one of the sensing devices to transmit thereto electrical signals indicative of an electrical characteristic (e.g., voltage) of the discrete region it contacts.

Electric vehicle battery pack frames constructed with extruded aluminum side and cross members. Such frames are significantly stronger than conventional cast aluminum frames, while also being much lighter than steel frames. Cross members may be affixed to side members with extruded aluminum brackets. Side members of differing lengths may be employed, to make battery pack frames of differing sizes in modular manner. Battery pack lids and bottom panels may be removably affixed to the frame such as with bolts, for improved serviceability.
