    MOSFETs are used in vehicles [19] such as automobiles, [20] cars, [21] trucks, [20] electric vehicles, [3] and smart cars. [22] MOSFETs are used for the electronic control unit (ECU), [23] while the power MOSFET and IGBT are used as the load drivers for automotive loads such as motors, solenoids, ignition coils, relays, heaters and lamps.

  3. 48-volt electrical system - Wikipedia

    en.wikipedia.org/wiki/48-volt_electrical_system

    A 48 V system can provide more power, improve energy recuperation, [7] and allow up to an 85% decrease in cable mass. [10]12-volt systems can provide only 3.5 kilowatts, while a 48 V power could achieve 15 to 20 kW or even 50 kW. 48 volts is below the level that is considered safe in dry conditions without special protective measures. [11]

  4. Relay - Wikipedia

    en.wikipedia.org/wiki/Relay

    Expected mechanical loads due to acceleration — some relays used in aerospace applications are designed to function in shock loads of 50 g, or more. Size — smaller relays often resist mechanical vibration and shock better than larger relays, because of the lower inertia of the moving parts and the higher natural frequencies of smaller parts ...

  5. Starter solenoid - Wikipedia

    en.wikipedia.org/wiki/Starter_solenoid

    The starter solenoid is sometimes called the starter relay, but many cars reserve that name for a separate relay which supplies power to the starter solenoid. In these cases, the ignition switch energizes the starter relay, which energizes the starter solenoid, which energizes the starter motor. The starter solenoid is above the starter motor.

  6. Power door locks - Wikipedia

    en.wikipedia.org/wiki/Power_door_locks

    Animation of how a power lock system works (simple relay operation) Power door locks (also known as electric door locks or central locking) allow the driver or front passenger to simultaneously lock or unlock all the doors of an automobile or truck, by pressing a button or flipping a switch.

  7. Electronic control unit - Wikipedia

    en.wikipedia.org/wiki/Electronic_control_unit

    An ECU from a Geo Storm. An electronic control unit (ECU), also known as an electronic control module (ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a car or other motor vehicle.

  8. High-voltage interface relay - Wikipedia

    en.wikipedia.org/wiki/High-voltage_interface_relay

    High voltage interface relays, a.k.a., interface relays: [1] [2] or coupling relays or insulating interfaces [3] [4] is a special class of electrical relays designed to provide informational and electrical compatibility between functional components isolated from each other and not allowing for a direct connection due to a high difference of potentials.
