An apparatus for updating a vehicle and a method thereof may calculate an update time for each update target of an over-the-air (OTA) update for the vehicle in which a battery is charged based on a charging schedule. The apparatus and the method may also perform the OTA update of the vehicle while the battery of the vehicle is being charged, in consideration of the update time for each update target and the charging schedule. By performing the update in conjunction with the charging schedule, it is possible to maintain a stable battery state.

A power supply device for a vehicle that includes two or more independent power sources, a simple low-power voltage monitor connected to a fast switch device, an electronic control unit (ECU), and a dedicated standby monitor element. Each power source has a separate path to connect to the load(s). That is to say, a primary path connects the primary power source to the one or more loads, and a backup path connects the backup power source to the one or more loads. Furthermore, each path includes a back-to-back blocking element, which prevents a direct connection between the primary power source and the backup power source. At standby, both or all paths are blocked except the standby monitor, ensuring extremely low quiescent current. When the system is ON, the voltage level of the power system is monitored; if the voltage level drops below a threshold level, then the paths are switched.

A battery module includes a plurality of pouch-type secondary batteries arranged to be stacked in at least one direction, each secondary battery having an electrode lead, and a bus bar made of an electrically conductive material and bonded to at least two electrode leads of corresponding secondary batteries to electrically connect the corresponding secondary batteries to each other. Each bonded electrode lead may be configured to protrude from the corresponding secondary battery in a front and rear direction, and at least one of left and right side surfaces of each bonded electrode lead may be bonded to the bus bar.

A battery pack includes a battery module having a plurality of battery cells; a lower plate on which the plurality of battery modules are placed; a support member coupled to the lower plate to support the battery module; and a mounting nut coupled to the lower plate and coupled to the support member so that the battery module is fastened by means of a bolt, wherein the battery module is in contact with the support member.

Provided is a scalable battery module. In once example embodiment, the module includes a plurality of submodules. Each plurality of submodules is configured to hold one or more cell batteries. The module further includes one or more of a first connector, a second connector, or a third connector. The first connector may secure an alignment of two or more adjacent submodules of the plurality of submodules along a first dimensional axis by using at least one of two slots and two projections of the first connector. The second connector secures the alignment of two adjacent submodules of the plurality of submodules along a second dimensional axis by using at least two further slots of the second connector. The third connector secures the alignment of two adjacent submodules of the plurality of submodules along a third dimensional axis by using at least two further projections of the third connector.

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.

Systems and methods for providing solar-generated power to a display unit mounted to a vehicle are provided. One or more mounting supports connect a housing for an electronic display to the vehicle. A solar energy harvesting device is secured to an upper portion of the vehicle and is electrically connected to the electronic display.

Embodiments of the invention relate to a drive system for armored electric vehicles and a method for its operation in event of a fire of the traction battery.

A drive system for a vehicle having a rear drive assembly powered by a first power source, a front drive assembly in selective electrical communication with a second power source, a selector switch to selectively permit or prevent electrical communication between the front drive assembly and the second power source, and an output capacity sensor to detect an output of the first power source, where the rear drive assembly drives the vehicle when the selector switch is in a first position and both the rear and front drive assemblies drive the vehicle when the selector switch is in a second position and the output capacity sensor detects that the output of the first power source meets a threshold output.

According to one embodiment, provided is an active material including monoclinic niobium titanium composite oxide particles, and carbon fibers with which at least a part of surfaces of the monoclinic niobium titanium composite oxide particles is covered. The monoclinic niobium titanium composite oxide particles satisfy 1.5≤(α/β)≤2.5. The monoclinic niobium titanium composite oxide particles have an average primary particle size of 0.05 μm to 2 μm. The carbon fibers contain one or more metal elements selected from the group consisting of Fe, Co and Ni, and satisfy 1/10000≤(γ/σ)≤ 1/100. The carbon fibers have an average fiber diameter in the range of 5 nm to 100 nm.
