The electric motor is configured to drive at least one of the front axle, the rear axle, or a component of the electrified vehicle. The trailer includes a trailer frame, a trailer axle coupled to the trailer frame, and an energy storage device supported by the trailer frame. The energy storage device includes a plurality of batteries. The energy storage device configured to power the electric motor.

A refuse vehicle includes a chassis, a body, and a plurality of battery cells. The chassis includes a right frame member and a left frame member spaced apart in a lateral direction and extending lengthwise in a longitudinal direction. The body is coupled to the chassis. The plurality of battery cells are longitudinally disposed along the chassis, positioned between the right frame member and the left frame member.

The present disclosure provides a system and method for selecting a battery pack that is used to pre-charge a high-voltage DC bus of an electric vehicle. A round-robin architecture is disclosed that prevents repeat selection of battery packs in order to prevent burnout of a resistor of the battery pack resulting from rapid subsequent pre-charging events. The system and method provided includes an easy solution that is scalable to a system with any number of battery packs, does not require any additional hardware, and is an inexpensive technique to protect an expensive component of the electric vehicle.

The present invention is an electric vehicle wherein the vehicle is powered by an internal generator rather than the traditional method of plugging in to charge the electric battery. The internal generator is made up of an alternator and a regulator which control the flow of electricity to the battery of the car. The battery of the car will only need to be charged once at the beginning of use or first time use of the vehicle and then will obtain power from the internal generator.

A bicycle battery system includes a battery tray that mounts within a cavity formed by an opening in a bicycle tube. The battery tray includes a latch mechanism, a first base portion that mounts to the latch mechanism, and a second base portion that mounts to the first base portion. The first base portion includes a cup that is sized to mate with an interior of the bicycle tube. The system also includes a battery that is sized to fit within the battery tray. A first end of the battery includes a protrusion that is sized to fit within the cup of the first base portion, and a second end of the battery includes a secondary latch to secure the second end to the battery tray. The system further includes a battery cover plate mounted to the battery.

A reinforcement frame (1) for a battery pack (2) of an electric or hybrid vehicle (37), the battery pack including a plurality of battery cells lying on and secured to a shield element, the reinforcement frame including at least: a reinforcement frame fastening portion (3) provided to be secured to both the battery pack and the body of the vehicle, and a reinforcement frame hollow portion (4) provided to surround at least the battery cells.

The present disclosure provides a battery pack housing, a battery pack, and an electric vehicle. The battery pack housing includes a housing body and at least one structural beam disposed in the housing body. The at least one structural beam divides the internal space of the housing body into a number of accommodation cavities. The housing body includes a top plate and a bottom plate arranged opposite to each other in a first direction, the first direction is a height direction of the battery pack housing, and the structural beam is located between and attached to the top plate and the bottom plate. The battery pack housing comprises a mounting part for connecting mounting portion for a fixed connection with an external load. The battery pack housing disclosed in the present disclosure has relatively high strength and stiffness as well as high space utilization.

Provided is a system including: a management unit configured to manage a plurality of battery packs connected in parallel, in which the management unit is configured to control the plurality of battery packs to cause the plurality of battery packs to be discharged alternately so that a discharge rate of each of the plurality of battery packs becomes higher than the discharge rate in a case of discharging all of the plurality of battery packs. The plurality of battery packs include a plurality of left-hand side battery packs and a plurality of right-hand side battery packs, and the management unit is configured to manage the plurality of battery packs to cause at least one of the plurality of battery packs in each of the plurality of left-hand side battery packs and the plurality of right-hand side battery packs to be discharged at a time in order.

A vehicle underbody structure includes a pair of rockers that are provided on both vehicle width direction sides of a vehicle underbody and extend in a vehicle front-rear direction, a battery that is disposed centrally in a vehicle width direction center between the pair of rockers and is disposed above a vehicle floor and on the lower side of a seat, a fuel tank that is disposed in the vehicle width direction center between the pair of rockers and is disposed under the vehicle floor and further toward a rear side of the vehicle than the battery, and a waste pipe that is coupled to a drive unit provided at a vehicle front side of the battery and extends in the vehicle front-rear direction between the battery and one of the rockers.

A system for preconditioning a power source of an electric aircraft is presented. The apparatus includes a power source of an electric aircraft, a computing device, and a user device. The computing device is configured to receive a flight plan, determine a predicted power usage model as a function of the flight plan, and initiate a power source modification on the electric aircraft as a function of the predicted power usage model. The user device is configured to display a flight performance infographic as a function of the predicted power usage model.
