Do BMW batteries self-charge?
When the automobile is parked and turned off, a BMW battery won’t start to recharge itself. Only when the engine is operating and there is an energy source (alternator) available will the battery be able to recharge. The battery will ultimately run out of power and need to be recharged if you have plugged-in equipment that is using the battery while the automobile is switched off and parked.
Additionally, the car contains a mechanism for recharging itself, however this function is dependent upon the engine being operating. When the car is parked, just a battery with a finite capacity is being used as an energy source. Additionally, the plugged-in device is the sole item drawing power from the battery; the battery is not being recharged at all.

Does the battery charge when the engine is revved?
Tom and Ray, When doing a jump start, my guy is adamant about revving the engine. When he starts the nice automobile, he revs it, and when he starts the bad car, he also revs it. Is there a justification for this action? When should you rev your engine and when is it appropriate?
Ray: Amanda, bad news. Your guy is essentially correct. I understand that’s not the information you were hoping for.
Tom: Within reason, revving the engine during a jumpstart is not a bad idea. Under no circumstances can the gas pedal be “floored.” However, your engine’s alternator also spins more quickly while your engine is running quicker. An alternator generates more electricity as it spins more quickly.
Ray explains that by boosting your engine’s speed to 2,000 or 2,500 rpm and maintaining it there while the other car tries to start, you can boost your alternator’s output and give your battery a little extra power that it can then give to the other car. That extra power can be significant depending on the size of the individual engines and battery health.
Tom: It’s also a good idea to make sure that all of the electrical accessories are off before jump-starting another vehicle. You can donate more if you use less electricity to power your own vehicle. Therefore, you should switch off the headlights, the air conditioner, the subwoofer, and the motorized buttscratcher.
Ray: The same regulations apply to the donee, or the vehicle receiving the jump start. All of the accessories should be turned off. In this manner, the alternator’s whole output can be used to recharge the battery. It is possible to accelerate the battery charge once the automobile has started, but driving is the most effective method.
Tom: You might need to drive it for 20 minutes or several hours, depending on how completely dead the battery was.
Ray: Good. Driving should be safe for 20 to 30 minutes if the dome light is only left on. But it might take a lot longer for the battery to fully recharge again if you left the headlights and the Easy-Bake Oven on all night. In fact, if it’s severely depleted, you might need to bring the vehicle to a gas station so the battery can be charged.
Tom: Of course, there’s also a chance that your battery is actually dead, or towards the end of its useful life. In that instance, driving to Fairbanks, Alaska, and back won’t recharge it. An updated battery is required. For this reason, once you jump-start your car and drive it for a time, make sure to stop it somewhere that’s “in the way,” like in front of some petrol pumps, before you try shutting it off and resuming it. That ensures that you will need another kickstart from someone!
