Is it bad to leave an electric car charger plugged in? Fortunately, it is not bad to leave your electric car plugged in or charge for an extended period. With electric cars being more effective to run and operate more than fossil fuel, they have grown in popularity significantly and the battery charging systems are designed so that damage will not occur while charging. They will trickle charge at the point where the charge is almost complete.
As the number of electric cars increases in the market, most individuals tend to ask questions about maintaining their cars’ batteries’ functionality. Therefore, in this article, I shall be answering some of these frequently asked questions. Such as, can just forget about my electric car and keep it plugged in whenever possible?
Can I leave my electric car charger plugged in all the time?
As stated earlier, leaving your electric car charger plugged in for an extended period is safe. Furthermore, it is standard practice, and the in-built battery management system significantly lowers the risk of overcharging.
The management system aids in lowering the down charging process once your car’s battery is near full charge. When it reaches 80-90% charged, the battery management system will trickle down the charging process.
Furthermore, electric cars will use up small amount of the battery charge in order to keep some electric functions run smoothly even when not in use. Trickle charging an EV helps in restoring fuller battery charge until the charger is unplugged. This means that you will always find your car charged well-enough and not overcharged.
Is it okay to leave an electric vehicle plugged in charging over the weekend?
Overcharging an electric car is almost impossible, thanks to its in-built battery management system. This means that leaving your electric vehicle plugged in charging over the weekend will not negatively impact your car.
With a tesla, you can set the maximum charge level. Once this level is reached the charging will stop even when the vehicle is still plugged in. Most people set the limit to be 80 percent because at that level, they can easily reach a supercharger in case they are getting low on a charge after taking a trip that is close to home.
Some electric car manufacturing companies advise users to leave their cars plugged in while they are parked at home. This is because electric cars have a maximum battery charge capacity it will allow, and when it is at this level, it will reduce the charging speed.
Also, if you have your car plugged in at home, you will still end up with an adequate travel range because your EV will not need to use up the battery charge to heat or to cool the inside of the car once you are ready to start your trip.
Plus, some on-board systems in electric cars run continually. For instance, a subroutine may keep the car’s battery at a constant temperature. This function will use a low amount of the battery charge while parked.
Can I leave my hybrid car plugged in overnight?
Just like an electric car, you can also leave your hybrid car plugged in overnight. In fact, leaving your hybrid car plugged in at night allows you to take advantage of the off-peak electrical hours; this means that you will be able to charge your car at a lower price.
In addition to that, hybrid cars are also fitted with an in-built battery management system. As a result, your car will not overcharge. Once your car reaches its capacity, it will stop charging automatically; therefore, your car’s battery will remain functional for an extended period.
Nevertheless, if you have fully charged it and then you try to top it off after a short voyage, the manual for the Outlander PHEV states that you should not do so. A top-up uses yet another charging cycle and all electric car and hybrid car batteries have a limited number of charge cycles. In other words, leave it plugged in when at home and try not to unplug it and plug it back in again too soon. Use a good portion of the charge before you do so.
Is it okay to be charging a cell phone in an electric car with the engine off?
No, it is never okay to charge your cell phone in an electric car with the engine off. It turns out that charging your phone in an electric car does more harm than good.

If the security system is updating photos to it, there is a chance that you are going to wear it out overtime. Each time that something is written to a flash drive, you are reducing its effectiveness.
However, if the flash drive only has data that is constant, leaving plugged in, is ok. Your electric car will not be accessing it and its lifespan will remain intact.
With respect to the health of the electric car, leaving a flash drive plugged in is not going to do any harm. Even though, you would drain the 12v battery if you were to read files that are on the flash drive if the engine is not running, the amount of power needed is small.
Most flash drives are not live all the time. They are just accessories that store files and that need to be activated by another device to read the files. Think of them as hard drives. A hard drive in a computer that is turned off, does not draw power.
Here is a video explaining ways to keep your 12-v battery in your electric car healthy, even if you have devices such as flash drives connected:
