A latch assembly for a closure panel and corresponding method of operation are provided. The assembly includes an actuation group to latch and unlatch the closure panel using power from a main power source during normal operation. A first backup energy source is selectively coupled to the actuation group and stores energy during normal operation and supplies the energy during a failure. A second backup energy source is selectively coupled to the first backup energy source and supplies energy thereto during the failure. A latch controller is coupled to the backup energy sources and detects latch operation and whether there is normal operation. The latch controller charges the first backup energy source using energy from the second backup energy source based on the detection of latch operation and the failure and disconnects the second backup energy source during normal operation to conserve energy stored in the second backup energy source.

The present disclosure relates to a closure latch assembly for a vehicle door, and more particularly to a closure latch assembly for a vehicle door equipped with a powered reset feature. To this end, the present disclosure relates to the use of a power actuator to actuate an actuatable mechanism in a power-on state, and an electronic reset circuit mechanism to reset the actuatable mechanism when the power actuator is in a power-off state. The electronic reset circuit mechanism is coupled to an electric motor associated with the power actuator.

A locking device is proposed to lock and/or to unlock a movable closure element like a door, a lid, etc. in a lockable object like a building, a ship, a vehicle, a train or the like, wherein the locking device has an electric control unit and/or a drive unit to control and/or to drive a movement of the movable closure element. The locking device shall be usable in applications without a handle for manual movements and is working with disconnected regular power supply. According to the invention, at least one supercapacitor is provided to store energy for operating the locking device in an emergency case.

An electrical latch for a closure system of a motor vehicle and method of operating are provided. The electrical latch includes a latching mechanism having a pawl and ratchet, a cinching mechanism having a cinching lever, and an electric actuator mechanism for actuating at least the cinching lever. The electrical latch further includes a control unit powered by a main power source and having a control circuit controlling operation of the actuator mechanism to affect the position of the cinch lever, and a backup energy source providing power to the control circuit and the actuator mechanism in the event a fault condition is experienced by the main power source. The electrical latch is configured to return the cinching lever to a home uncinched position in response to switching of power from the main power source to the backup energy source.
