It is possible to charge your car battery when driving in cities and towns, it will just take longer.
Why is my car battery not charging at high speeds?
The faster you’re driving, the more power the alternator can generate, and thus the faster your battery will charge. Of course, there are limits to this effect. If your battery is severely depleted, it may not charge sufficiently even while you’re driving at high speeds.
How long should you drive your car to charge the battery?
If your car battery has been sitting for some time, then driving it around for 30 minutes may not fully recharge it.

Why does my alternator not charge the battery?
This is because your alternator is actually powered by the engine, so as long as it is making enough rpm’s, it should charge the battery. The only catch is that it doesn’t charge very quickly. This is due to the fact that the engine has no load on it when your car is idling. Meaning idling RPMs are much lower than RPMs when driving down the road.
Does driving slower save battery life?

Then, instead of drawing more energy from its battery storage, the electric car uses a large portion of the energy that was previously stored during regenerative braking on acceleration. However, you should also educate yourself on how electric cars lose battery when parked for long.
Why do electric cars lose range over time?
The conclusion is that the batteries supply more power to run all of these functions at high speed, utilizing more energy, which affects the range. Also, high speed will result in a reduction in battery life. Electric cars also lose range over time as the battery wears.
Does driving slower save battery?
Slow Down You’ll not only avoid getting a speeding ticket, you’ll bolster your battery range in the process. The Department of Energy says you’ll use 14% less energy by reducing your speed by 10 mph.
Is it better to drive fast or slower?
Here is the dilemma: If you drive fast, it takes more gas, which costs more money. If you drive slower, it takes less gas, so you will save money. But you will also sacrifice time—time you could spend on the clock at work, earning money. There should be some optimal driving speed at which the total cost (gasoline plus missed work) is minimized.
