Energy Reserve
Energy ReserveAt the same time the energy reserve is charged. The energy reserve consists of a storage capacitor (60 V). If the vehicle voltage drops below a defined threshold, power is tapped from the energy reserve. In this way, the entire functionality of the safety system is maintained for approximately 1 second, the time it takes to drain the energy reserve.
Note: When carrying out work on the safety system, always bear in mind that the storage capacitors take a few seconds to discharge after the battery has been disconnected, and the safety system remains operational for this period of time.
