Modern engines shouldn't be run just for a few minutes and then shut down. The oil gets contaminated with cold engine chemistry that only "hot" oil can properly deal with. * I don't know details on the car that is causing problems but if it contains a computer sub-system, it may be the kind that stays on all the time. That should be checked. * For street parked car charging....suggestion. Small 12volt solar panels, say about 5"x 8", etc. are really cheap now. They put out about 1/4 to 1/2 amp. Which is fine for light charging of a car battery. Attach it to a cigarette cable and plug it into the cigarette socket in the dash. Place the unit on the car dash so it gets the sun. However, there is a key warning about these small solar panels. Most of The 12 volt units can go as high as 18 Volts. Thus if the car battery is fully charged the panel could continue to trickle charge it. The battery could start to slowly "gas" as the voltage raises. A low cost modification can stop this over-charging. Using a zener diode or similar to protect the battery from the higher charging voltage problem. You may be able to find a solar unit that already has this builtin protection or a friend that can modify the it.

Asian vehicles and many European vehicles only supply power to the cigarette/power port with the ignition switch in the Accessory or Run positions, so the power generated by the solar panel would not be delivered to the battery on those vehicles.
