US 11,962,147 B2 · Circuit and system for coupling battery packs to motor controller in electric or hybrid aircraft

Abstract

The present disclosure describes at least a coupling circuit for powering an electric or hybrid aircraft with an output voltage. The couple circuit can include multiple connecting inputs, a charging interface, a connecting output, a high-power diodes arrangement, and a pre-charge circuit. The multiple connecting inputs can connect multiple battery packs. The charging interface can connect to a charger for charging the multiple battery packs. The connecting output can connect with a hardware controller. The high-power diodes arrangement can electrically connect to each respective connecting input and the charging interface. The high-power arrangement can include for each battery pack a first high-power diode and a second high-power diode. The pre-charge circuit can electrically connect to the high-power diode arrangement. The pre-charge circuit can include a first branch with a first switch, and a second branch in parallel with the first branch.
