The present disclosure relates to methods and associated systems for operating a battery exchange station. The present method includes (1) receiving a ratio associated with a plurality of vehicles served by the battery exchange station; and (2) based on the ratio, storing different sets of information in memories associated with the batteries respectively, in accordance with received ratio.

An update providing apparatus of a vehicle is provided. The apparatus includes a communication circuit that communicates wirelessly with a server, a battery, and a control circuit. The control circuit is electrically connected to the communication circuit and the battery and obtains update data associated with a target controller mounted within the vehicle, from the server. Accordingly, the control circuit calculates an estimated remaining amount upon completing an update, based on an estimated required time of the update, an estimated required time of a roll-back, and a current remaining amount of the battery and performs the update on the target controller, when the estimated remaining amount satisfies a particular condition.

This disclosure relates to an electrified vehicle with an auxiliary battery rack, which has a collapsible frame, and a corresponding method. In particular, the auxiliary battery rack is located at least partially within a storage compartment of the electrified vehicle. The auxiliary battery rack includes a frame configurable in a support position and a collapsed position in which the frame occupies less volume in the storage compartment than when in the support position.

A through the road (TTR) hybridization strategy is proposed to facilitate introduction of hybrid electric vehicle technology in a significant portion of current and expected trucking fleets. In some cases, the technologies can be retrofitted onto an existing vehicle (e.g., a trailer, a tractor-trailer configuration, etc.). In some cases, the technologies can be built into new vehicles. In some cases, one vehicle may be built or retrofitted to operate in tandem with another and provide the hybridization benefits contemplated herein. By supplementing motive forces delivered through a primary drivetrain and fuel-fed engine with supplemental torque delivered at one or more electrically-powered drive axles, improvements in overall fuel efficiency and performance may be delivered, typically without significant redesign of existing components and systems that have been proven in the trucking industry.

Methods for wirelessly communicating with vehicle adapted to be at least partially powered by a human are disclosed. An example method may include transmitting data from a device remote from the vehicle and configured to communicate with the vehicle, receiving the data at the vehicle, and configuring a parameter of the vehicle based on the data.

Vehicles may be composed of a relatively few number of modules that are assembled together during a final assembly process. An example vehicle may include a body module, a first drive module coupled to a first end of the body module, and a second drive module coupled to a second end of the body module. One or both of the drive modules may include a pair of wheels, a battery, an electric drive motor, and/or a heating ventilation and air conditioning (HVAC) system. One or both of the drive modules may also include a crash structure to absorb impacts. If a component of a drive module fails or is damaged, the drive module can be quickly and easily replaced with a new drive module, minimizing vehicle down time.

A software update device is connected to a control device and includes an update control unit executing an update process of causing software for the control device to transit from a non-updated state to a completely updated state, a recovery control information managing unit acquiring recovery control information, and a recovery control unit executing a recovery process of causing the software to transit to the completely updated state on a basis of the recovery control information in a case where an abnormality in the update process has prevented the software from transiting to the completely updated state.

The present invention relates to a method for converting a diesel-electric, or diesel hydraulic rail vehicle to an all-electric rail vehicle capable of moving on partially electrified railway tracks, comprising providing the vehicle a storage and autonomous supply electric power system comprising an electric traction unit, if not present in the vehicle prior to the conversion, or if the existing electric traction unit is to be replaced; an accumulator unit comprising one or more electricity accumulators, and a super capacitor unit comprising one or more super-capacitive assemblies; a power supply device for supplying external power when available to the traction and the storage and supply system, and a control and distribution system for distributing electric power between the traction system, the power supply device and the electric power storage and autonomous supply system according to the traction operation and availability of external power.

Systems, devices, and methods are disclosed for determining whether to provide an over-the-air (OTA) update to a vehicle. An example method includes determining an update characteristic of a pending software update for a vehicle. The method also includes determining a vehicle battery state of charge (SOC) threshold based on the update characteristic. The method further includes modifying the threshold based on a location of the vehicle. The method still further includes determining a SOC of a battery of the vehicle. And the method yet further includes responsively providing the pending software update to the vehicle based on the SOC and the threshold.
