  • Patent number: 11005135
    Abstract: This disclosure relates to a battery arrangement for an electrified vehicle. Among other things, the battery arrangement includes first and second battery modules, each of which includes a battery module housing. Adjacent surfaces of these battery module housings are interlocked such that the first and second battery modules are configured to slide relative to one another in a transverse direction of the electrified vehicle. Accordingly, this disclosure increases safety while saving space and without requiring undue reinforcements of the chassis structure, which would increase the weight of the vehicle and reduce the energy efficiency the vehicle. These and other benefits will be appreciated from the following description.

  • Patent number: 11002666
    Abstract: A system for facilitating the measurement of optical parameters of a substance sitting on a surface, so that identification of the substance by reflectance spectroscopy can be made without ambiguity; the system comprises a structure using a bistatic arrangement and an accompanying method to limit, to just two beams, the propagation of light from a laser transmitter capable of producing coherent light of multiple wavelengths, via an interposed transparent dielectric, to a receiver thereby preventing multiple reflections within the transparent dielectric from reaching the receiver; and the bistatic arrangement comprises a multi-wavelength laser transmitter and a receiver mounted on a telescoping boom, with both the laser transmitter and receiver being independently orientable, with the positions and orientations of the laser transmitter, the receiver and the telescoping boom electronically sensed at all times.

  • Patent number: 10976371
    Abstract: A battery monitoring device includes a monitoring control unit configured to monitor a battery state of each battery cell of a battery module formed by arranging the plurality of battery cells and control each of the battery cells on the basis of a monitoring result. The monitoring control unit has a heat radiation source that radiates heat as an electric current flows, and the heat radiation source is arranged in a position where air discharged from a gap between the neighboring battery cells collides with the heat radiation source. For example, the heat radiation source is arranged to face an outlet port from which the air of the gap between the neighboring battery cells is discharged.

  • Patent number: 10973714
    Abstract: An electrically assisted wheelchair includes a controller that obtains an inclination assist value by correcting the assist value when a road surface is inclined in a left-right direction of the seat, and performs a downhill turning preventing operation of causing the wheelchair body to travel straight by applying right auxiliary power and left auxiliary power corresponding to the inclination assist value. The controller adjusts the right auxiliary power and the left auxiliary power by correcting the inclination assist value based on a hand rim operation of the user to operate at least one of the right hand rim and the left hand rim in the downhill turning preventing operation.

  • Patent number: 10960771
    Abstract: A method is provided for increasing the operating range of a vehicle which is driven by an electric motor. The method determines that a state of charge reserve of an energy store of the vehicle should be used for operating the electric motor. The state of charge reserve lies outside a state of charge range which is intended for the energy store. In response to this, the method uses electrical energy from the state of charge reserve of the energy store in order to operate the electric motor of the vehicle.
