Your car was designed to have a battery maintainer (not a trickle charger) plugged into the cigarette lighter socket for prolonged periods without any harmful effects.

"Trickle chargers" never shut off or reduce voltage, which can cook a battery over time; battery maintainers vary the voltage and amperage input according to the battery's condition, and can be left connected indefinitely.
