2. 42-volt electrical system - Wikipedia

   en.wikipedia.org/wiki/42-volt_electrical_system

   [1] 42 volts is an approximation of the output of the new standard's charging system. [2] The present nominally 12 V automotive electrical system usually operates around 13.8 volts, so 14 V is descriptive. Literature on 42-volt electrical systems often refers to systems powered with a 6-cell lead-acid battery as nominally 14 volts.

3. Alternator (automotive) - Wikipedia

   en.wikipedia.org/wiki/Alternator_(automotive)

   Alternator (silver) mounted on a V8 engine. An alternator is a type of electric generator used in modern automobiles to charge the battery and to power the electrical system when its engine is running. Until the 1960s, automobiles used DC dynamo generators with commutators.

4. Jump start (vehicle) - Wikipedia

   en.wikipedia.org/wiki/Jump_start_(vehicle)

   Jumper cables should not be used to interconnect between different voltage systems; for example, connecting 6V and 12V systems together may cause damage. [5] If the dead battery is physically damaged, has a low electrolyte level, is decayed or frozen, a jump start will not repair the battery. A vehicle with a frozen battery should not be jump ...

5. Battery indicator - Wikipedia

   en.wikipedia.org/wiki/Battery_indicator

   This indicates whether the battery is being charged or discharged. In the adjacent picture, the ammeter is marked "Alternator" and the symbols are "C" (charge) and "D" (discharge). Both ammeters and voltmeters individually or together can be used to assess the operating state of an automobile battery and charging system.

6. Load dump - Wikipedia

   en.wikipedia.org/wiki/Load_dump

   If the battery becomes disconnected while it is being charged the load on the alternator suddenly decreases. However, the vehicle's voltage regulator cannot quickly cause the field current to decrease sufficiently, so the alternator continues to generate a large current. This large current causes the voltage on the vehicle bus to increase ...

7. Alternator - Wikipedia

   en.wikipedia.org/wiki/Alternator

   Alternator mounted on an automobile engine with a serpentine belt pulley (belt not present.) Alternators are used in modern internal combustion engine automobiles to charge the battery and to power the electrical system when its engine is running. [citation needed] Until the 1960s, automobiles used DC dynamo generators with commutators.

9. Automotive battery - Wikipedia

   en.wikipedia.org/wiki/Automotive_battery

   A typical 12 V, 40 Ah lead-acid car 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.
