2. 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.

   What To Expect. Estimated Time: 10–15 minutes. Experience Level: Beginner. If you can't find the battery terminals under the hood, checking the owner's manual can save you a lot of time.

4. Jump start (vehicle) - Wikipedia

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

   Very small trickle chargers are intended only to maintain a charge on a parked or stored vehicle, but larger chargers can put enough charge into a battery to allow a start within a few minutes. Battery chargers may be strictly manual, or may include controls for time and charging voltage. Battery chargers that apply a high voltage (for example ...

5. 42-volt electrical system - Wikipedia

   en.wikipedia.org/wiki/42-volt_electrical_system

   The European auto manufacturer Daimler-Benz proposed a 42V brand name for the conversion. Although many manufacturers were predicting a switch to 36-volt (lithium-ion battery) / 42-volt (charging voltage) electrical systems, the "42V" changeover did not occur by early in the 21st century, and plans were mostly abandoned by 2009. [1]

6. Lead–acid battery - Wikipedia

   en.wikipedia.org/wiki/Lead–acid_battery

   About 60% of the weight of an automotive-type lead–acid battery rated around 60 A·h is lead or internal parts made of lead; the balance is electrolyte, separators, and the case. [8] For example, there are approximately 8.7 kilograms (19 lb) of lead in a typical 14.5-kilogram (32 lb) battery.

7. Ignition coil - Wikipedia

   en.wikipedia.org/wiki/Ignition_coil

   When the electrical circuit connected from the power source (e.g. the car's battery) to the primary winding is closed (by a contact breaker or transistor), current flows through the primary winding, which produces a magnetic field around the core. This current flow lasts for a period of time to build up energy in the coil.

8. 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]

9. IUoU battery charging - Wikipedia

   en.wikipedia.org/wiki/IUoU_battery_charging

   In practice, it depends on the capability of the charger. The battery capacity C is expressed in Ah units, typically the C 20 value based on a 20-hour discharge time. [3] The charging current (in A units) can be written as C/t where t is a time. For example, for a battery with C = 40 Ah, a current C/10 is equal to 4 A. The charging current is a ...
