   The actual voltage, matching the car battery's voltage, will be approximately 12.5 volts when dormant (less in cold conditions), approximately 14.5 volts when the engine and the alternator/generator are operating (more when cold), and may briefly drop as low as 5–6 volts during engine start due to the high temporary battery current usage.

   These connectors are sometimes informally referred to as chargers, but they are "electric vehicle supply equipment" (EVSE), since they only supply AC power to the vehicle's on-board charger, which then converts it to the direct current (DC) needed to recharge the battery. The Combined Charging System (CCS) Combo 1 connector builds on the ...

   The automobile self starter was an early engine system to use this. Lighting, which had previously been provided by kerosene lamps or gas lamps, was one of the first common electrical accessories. Early systems used 6 volts, but 12 volts became the standard because it provided greater power with less current.

6. Current sensing - Wikipedia

   en.wikipedia.org/wiki/Current_sensing

   In electrical engineering, current sensing is any one of several techniques used to measure electric current. The measurement of current ranges from picoamps to tens of thousands of amperes. The selection of a current sensing method depends on requirements such as magnitude, accuracy, bandwidth, robustness, cost, isolation or size. The current ...
