  • Patent number: 10389167
    Abstract: A method for distributing power using multiple power sources is performed by a control device electrically connected to multiple rechargeable power units and a load. The control device creates an output power reference table according to multiple power setting values, output power ranges and battery efficiencies of the multiple rechargeable power units. The output power reference table includes the power setting values and power distribution information corresponding to the power setting values. When receiving a consumed power value of the load, the control device selects corresponding power setting value and power distribution information in the output power reference table and controls the multiple rechargeable power units to simultaneously output power to the load according to the power distribution information. By referring to the output power values of all the rechargeable power units and allocating power outputted from all the rechargeable power units, power utilization efficiency can be enhanced.

  • Patent number: 10377263
    Abstract: In one aspect, the invention is a shifter for a vehicle driven by an electric motor powered by a battery. The shifter includes a lever with one end adapted to accommodate the hand of a user and another end moveably attached to a base mounted on the vehicle. The base includes a mechanism biasing the lever into an equilibrium position and providing haptic feedback when moved in one direction out of the equilibrium position. The shifter also includes at least one sensor adapted to detect when the lever is moved in the one direction and to send a downshift signal to a processor. The processor is adapted to switch the motor to a power generation mode in response to the signal, thereby charging the battery and slowing the vehicle. The net effect is to simulate downshifting a manual transmission in a gas-powered vehicle. In another aspect, the base includes a mechanism providing haptic feedback when moved to one of a plurality of positions.
