Latch assembly with hybrid backup energy source

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.
