  • Publication number: 20250121690
    Abstract: A discharge system for a drive system includes a discharge circuit, a sensor, and a control system. The discharge circuit is connected in parallel to the drive system, and is operable in an ON-position to be electrically coupled to the drive system or an OFF-position to be electrically decoupled from the drive system. The sensor is arranged in series with the discharge circuit to detect an electrical characteristic of the discharge circuit. The control system is configured to, for a diagnostic check, operate the discharge circuit in the ON-position, and provide a notification in response to the electric characteristic detected being unresponsive to the discharge circuit being in the ON-position.

  • Patent number: 12194876
    Abstract: A traction powertrain system of an electrified vehicle includes a power electronics module and a controller. The power electronics module, such as in the form of an inverter, is configured to drive a traction motor with power from a traction battery via a DC-link capacitor. The controller has an on-board power source, such as in the form of a super capacitor. The controller is configured to, in response to detecting an event in which the DC-link capacitor is to be discharged, use power from the on-board power source for controlling the power electronics module and control the power electronics module to operate in a manner causing the DC-link capacitor to be discharged.

  • Publication number: 20240416763
    Abstract: A system for an electrified vehicle, such as a battery electric vehicle (BEV), includes an inverter configured to drive a motor having motor windings with electrical power from a battery according to a configuration of a power switch of the inverter. The system further includes a capacitor connected between a center-tap of the battery and a neutral-point of the motor winding whereby the capacitor and the motor windings form an LC circuit. The system further includes a controller configured to operate the power switch in a zero-current-switching mode with a switching frequency dependent on a resonant frequency of the LC circuit to thereby cause electrical current to circulate between the battery, the inverter, and the motor which heats the battery and the motor windings.

  • Publication number: 20240371561
    Abstract: An electric drive system includes an actively cooled inductor. The inductor is formed by winding C-shaped wire around a bobbin such that channels are defined between the bobbin and the wire. After the bobbin is installed over the core, a plastic layer is injected between the core and the bobbin. This expands the bobbin against the wire to seal the channels and also to fasten the bobbin in place. A variety of porting arrangements are proposed to route cooling fluid through the channels to cool the windings and the core.

  • Patent number: 12132417
    Abstract: A power converter includes a pair of series connected switches and circuitry. The circuitry includes another switch and an optocoupler that activates responsive to changes in current through one of the series connected switches exceeding a predefined threshold. Activation of the optocoupler causes the another switch to conduct and reduce a gate voltage of the one of the series connected switches to reduce the changes in current through the one of the series connected switches.

  • Patent number: 12072012
    Abstract: A hybrid transmission has a housing with two chambers. One chamber contains electric motors and other transmission components that require a liquid lubricant and coolant such as automatic transmission fluid. The other chamber contains power electronics that must be isolated from the liquid lubricant/coolant. To reduce the number of breather tubes required, it is beneficial if air can move between the chambers. A terminal block cooperates with a separating wall between the two chambers to create a labyrinth seal between the chambers.
