Abstract
A powertrain controller for an electric vehicle (EV) includes a compressor controller configured to regulate three-phases of electrical current supplied by a vehicle battery of the EV or an electric motor of the EV to an electrically-actuated compressor; and a load bank controller configured to regulate a fourth-phase of electrical current provided by the vehicle battery or the electric motor of the EV to a resistive load bank, such that the compressor controller and the load bank controller are integrated into a common control system.
Claims14
A powertrain controller for an electric vehicle (EV), comprising:
- a compressor controller configured to regulate three-phases of electrical current supplied by a vehicle battery of the EV or an electric motor of the EV to an electrically-actuated compressor;
- and
- a load bank controller configured to regulate a fourth-phase of electrical current provided by the vehicle battery or the electric motor of the EV to a resistive load bank, wherein the compressor controller and the load bank controller are integrated into a common control system.
A powertrain controller for an electric vehicle (EV), comprising:
- a compressor controller, configured to electrically couple with an electrically-actuated compressor, that regulates three-phases of electrical current supplied by a vehicle battery of the EV or an electric motor of the EV to the electrically-actuated compressor;
- and
- a load bank controller configured to regulate a fourth phase of electrical current provided by the vehicle battery or the electric motor of the EV to a resistive load bank, wherein the compressor controller and the load bank controller are both within a powertrain controller housing.
A powertrain controller for an electric vehicle (EV), comprising:
- an electrically-actuated compressor electrically connected to a control system of the powertrain controller;
- a resistive load bank, including a plurality of resistors electrically connected together, that is electrically connected to the control system of the powertrain controller;
- and
- a resistor housing that receives the resistive load bank and is in fluid communication with the compressor portion of the electrically-actuated compressor that cools the resistors,
- wherein the control system is configured to receive electrical current from a vehicle battery or an electric motor used by the EV for propulsion and provide three-phase electrical current to the electrically-actuated compressor and a fourth-phase of electrical current to the resistive load bank.
A powertrain controller for an electric vehicle (EV), comprising:
- a compressor controller configured to regulate three-phase alternating current (AC) electrical current to an electrically-actuated compressor;
- and
- a load bank controller including a DC chopper circuit configured to regulate a fourth-phase of electrical current provided to a resistive load bank, wherein the compressor controller and the load bank controller are integrated into a common enclosure and share at least some electrical components.
