VEHICLE CONTROLLER, VEHICLE, POWER SUPPLY SYSTEM, DISCHARGE CONNECTOR, POWER EQUIPMENT, AND POWER SUPPLY METHOD

A vehicle includes: an on-board inverter that adjusts the voltage of an electric power; and a vehicle inlet. The vehicle inlet has a CS terminal through which a proximity detection signal for identifying the connection state between a discharge connector and the vehicle inlet is transmitted. An electronic control unit (ECU) includes a processor that selects the voltage of an electric power output from the on-board inverter. When the proximity detection signal is in a first bound (a fourth range or a fifth range), the processor selects AC 100V, and when the proximity detection signal is in a second bound (a fifth range or a sixth range) at least partially different from the first bound, the processor selects AC 200V higher than AC 100V.

20230045807 · 2023-02-16 ·

A method controls the current output of a battery for driving a rail vehicle. A battery actual current I.sub.bat,ist passes via a converter to an asynchronous motor, being a drive for the vehicle. The battery actual current I.sub.bat,ist is set by control circuits as a function of a feedforward control torque M.sub.ff and a specified torque M.sub.tf. The feedforward control torque M.sub.ff is calculated using a transfer function H.sub.sys(z), which maps the torque setpoint value M.sub.soll onto the battery actual current I.sub.bat,ist as follows: I.sub.bat(z) H.sub.sys(z) M.sub.soll(z). Accordingly, a zero-point z=znmp, which lies outside the unit circle, is determined by the transfer function H.sub.sys(z). The feedforward control torque M.sub.ff is calculated as follows: M.sub.ff(z) I.sub.bat,neu(z)/(H.sub.sys(z) z) where: I.sub.bat,neu(z)=I.sub.bat,ideal(z) I.sub.bat,ideal(z=znmp) where: I.sub.bat,neu[n]=I.sub.bat,ideal[n] for all n>0, so that pole point/zero point cancellation is reached by z=znmp at the battery ideal current.
