The present application generally relates to battery powered door unlock mechanisms. More specifically, the application teaches an unlock system including a door unlock mechanism, a capacitive circuit having a first time response, a resistive-capacitive circuit having a second time response wherein the second time response is longer than the first time response, a battery for coupling a battery charge to the capacitive circuit and the resistive capacitive circuit in response to a door unlock authentication signal, and a relay for coupling a first charge from the capacitive circuit to the door unlock mechanism in response to the relay being activated by a second charge from the resistive-capacitive circuit after the second time response.

An entry backup energy assembly is provided for an electric latch that is powered by a main power source during a normal operating condition. The entry backup energy assembly includes a backup battery electrically coupled to an activation switch that is moveable to one of an activated state and a deactivated state. The entry backup energy assembly also includes a backup controller coupled to the activation switch and the backup battery and the electric latch. The backup controller is configured to receive power from the backup battery in response to movement of the activation switch to the activated state and wirelessly communicates with a user authentication unit to authenticate a user. The backup controller provides the backup electrical energy to the electric latch and enables the user to operate the electric latch during a failure operating condition in response to the user being authenticated.

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.
