The charging voltage for a battery is 14 volts. It can use to charge the battery when the engine is not running. It is because when the engine runs, it produces more power than when it’s off, so it’s not needed to charge the battery.

Charge With Solar Power

Focusing on a solar panel, charge controller, and battery would help to have a solar-powered car. The charge controller handles the movement of electrical power from the solar panel to the battery. The solar panel generates direct current (DC) energy from sunlight.

Once your car battery is fully recharged, the battery controller will stop energy flow. You can charge your automobile with a solar panel in two ways: direct charging and trickle charging. Direct charging means connecting your car battery to sunlight.

The overcharge can destroy a thunderstorm. For this reason, it’s better to use trickle charging. It involves attaching the battery to the solar panel and the controller. When the controller charges the battery at a low rate, it will gradually charge itself overnight. Don’t discharge the battery for more than 14 hours for the best results.
