Description And Operation: Operation
The electrical system is designed to increase the vehicles safety level and prevents the possibility of electrical malfunctions. State- of- the-art connectors have been introduced to rule out the possibility of many connection defects.
The power distribution is supplied via the Power Distribution Center (PDC) and Body Control Module (BCM). These are connected to the control elements (such as relays and actuators) ensure maximum electrical protection and minimum complexity.
The main security solutions are adopted:
- Power supply protection by fuses for the interruption of the electrical system, in case of short circuit
- The lay-out of the entire system is optimized for the reduction of risk of damage in case of damage or accident
- The laying of the cables has been optimized by reducing incorrect placements, and noise due to vibration
- All cables are high abrasion resistance
- In the engine compartment cables are of special, high temperature resistance and are protected with sheaths or pipes
- The cables in the passenger compartment are protected by corrugated tubes and tapes with micro-fleece to reduce noise
- The main connections are equipped with anti-slip device terminals (secondary lock) and a safety lock (lock lever) which avoids any deformation of the terminals.
A power socket is located in the console which can be used for the cigar lighter or for connecting instruments or equipment operating on 12 volts. The luggage compartment contains a second power socket similar to the first on the left hand side. The sockets are equipped with a thermal protection device: this protection cuts off the power supply if devices that absorb a lot of energy are connected. Do not connect devices with power higher than 180 watts to the socket. Do not damage the sockets by using unsuitable adaptors. A USB port for recharging electronic device provided with 12 volt charging adapters is located on the tunnel console in the electronic key compartment. The socket is powered in two ways, one directly and one "ignition-operated power supply - start-up excluded. The circuits of the power sockets is protected by a specific fuse and controlled by switched ignition power supply relay (+15) located in the boot junction box.
The power socket is supplied power by the ignition-operated power supply line protected fuse from the BCM. The rear power socket is powered by a line protected fuse from the PDC, the power is controlled by a relay which is an ignition feed power from the BCM. The USB port is powered directly from the battery by a line protected fuse from the PDC.
All systems and electrical systems are supplied by the battery with 12 volts. The battery in turn is recharged during operation of the generator.
On versions equipped with Electric Stop Start (ESS), the battery status is monitored continuously by an Intelligent Battery Sensor (IBS) located on the negative pole of the battery.
The main power supply lines are fuse protected. Those fuses are contained in the box on the positive battery terminal pre-fuse assembly.
Some circuits employ "J-House" fuses: this is a cartridge type fuse with the characteristics to ensure a lower voltage drop for the protection of circuits that absorb high current.
