  • Patent number: 7560884
    Abstract: An electronic braking and energy recycling system associated with a direct current (DC) brushless motor, characterized in that when an electronic braking task is launched, a phase voltage occurred in an inverse mode is applied onto a motor coil corresponding thereto and a gate voltage signal with positive and negative cycles is used to control an upper-side and lower-side branches to switch as compared to each other in the system, so as to redirect a current flown through the motor back to a power source end. In this invention, a controllable inverse torsion is achieved, enabling an electrical machine to be braked smoothly and reliably when necessary. As such, a dynamic power of the motor can be recycled at a maximum rate and thus the purpose of energy recycling is achieved. In addition, no complex circuitry configuration owing to the multi-phase coils is required.

  • Patent number: 7148637
    Abstract: A portable compound battery unit management system comprises a portable high capacity battery unit, a main power battery unit, and a DC converter. The portable high capacity battery unit has a built-in battery management means and is connected to the DC converter. The main power battery unit supplies power to a motor which in turn drives the vehicle, and contains another battery management means or a device for limiting maximum output current, or provides the DC converter and a motor controller installed behind with battery information required to operate the vehicle. The DC converter transfers the electrical energy of the portable high capacity battery unit to the main power battery unit, or converts output power of the portable high capacity battery unit to a necessary power required to operate the motor controller, wherein it has boost up or buck down function of voltage to match the voltage difference between the two battery units.
