Status Panel PM PEMS E-Box • Distribution • Fuses • Emergency-Stop / 167 AVL M.O.V.E POWER SUPPLY Vehicle Installation In addition to device installation, power supply strongly depends on different use cases and customer philosophies. Customers today follow a broad range of power supply strategies including mains power (for system heat-up), generators (long-term independent operation), batteries (short-term independent operation) and/or vehicle power supply. SOLUTION All AVL M.O.V.E devices operate on 24 VDC power. The power supply concept is designed for operation of the M.O.V.E devices independently of the vehicle power supply. The E-Box provides the following features: Handling of power sources: The E-Box enables the user to seamlessly switch between different power sources such as mains/generator power during system heat-up and batteries for back-up power supply. Power distribution: The E-Box distributes the power to the M.O.V.E devices and at the same time ensures safe battery loading (different battery types and sizes are supported). The system monitors the energy flows and shows the remaining battery power on a display. Device and cable protection: All connectors are protected against polarity reversal. The safety concept involves separate fuses for all inlets and outlets. Emergency stop: Upon pressing the emergency stop button, all critical components of the M.O.V.E system (e.g. heated lines etc.) are immediately disconnected from power. However, communication between the devices remains active in order to avoid any damage that can be caused by a complete shutdown.
