2. Jump start (vehicle) - Wikipedia

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

   Trucks usually have a 24 V supply using two 12 V automotive batteries in series: it is therefore possible to jump-start a vehicle with a 12 V electrical system using only one of the two batteries. [11] Vintage cars may have 6-volt electrical systems, or may connect the positive terminal of the battery to the chassis.

3. Series and parallel circuits - Wikipedia

   en.wikipedia.org/wiki/Series_and_parallel_circuits

   If the cells are connected in series, the voltage of the battery will be the sum of the cell voltages. For example, a 12 volt car battery contains six 2-volt cells connected in series. Some vehicles, such as trucks, have two 12 volt batteries in series to feed the 24-volt system.

4. Battery terminal - Wikipedia

   en.wikipedia.org/wiki/Battery_terminal

   Automotive batteries typically have one of three types of terminals.. In recent years, the most common design was the SAE Post, consisting of two lead posts in the shape of truncated cones, positioned on the top of the battery, with slightly different diameters to ensure correct electrical polarity.

   Electric vehicle sales are booming. The International Energy Agency says more than 10 million EVs were sold worldwide in 2022, and their share of the overall car market rose from 4% in 2020 to 14% ...

6. Electrochemical cell - Wikipedia

   en.wikipedia.org/wiki/Electrochemical_cell

   The alternator, once the car is running, recharges the battery. It can perform as a galvanic cell and an electrolytic cell. It is a convenient way to store electricity: when current flows one way, the levels of one or more chemicals build up (charging); while it is discharging, they reduce and the resulting electromotive force can do work.

7. 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.

   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.
