  4. Automotive battery - Wikipedia

    en.wikipedia.org/wiki/Automotive_battery

    An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle. Its main purpose is to provide an electric current to the electric-powered starting motor , which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.

  7. Battery management system - Wikipedia

    en.wikipedia.org/wiki/Battery_management_system

    A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack) by facilitating the safe usage and a long life of the battery in practical scenarios while monitoring and estimating its various states (such as state of health and state of charge), [1] calculating secondary data, reporting that data, controlling its environment ...

  8. Current sensing - Wikipedia

    en.wikipedia.org/wiki/Current_sensing

    The design of the saturable inductor current sensor is similar to that of a closed-loop Hall-effect current sensor; the only difference is that this method uses the saturable inductor instead of the Hall-effect sensor in the air gap. Saturable inductor current sensor is based on the detection of an inductance change. The saturable inductor is ...

  9. Contact breaker - Wikipedia

    en.wikipedia.org/wiki/Contact_breaker

    The contact breaker is operated by an engine-driven cam.On an engine with a distributor, the contact breaker can be found beneath the distributor cap.The position of the contact breaker is set so that it opens (and hence generates a spark) at exactly the optimum moment to ignite the fuel/air mixture.
