Electric vehicles (EVs) are still rare compared to combustion vehicles. People want to know if having extra passengers drains your EV batteries. Just like leaving the car lights on drains a car battery. Did you know that your car battery, combustion, or EV, drains for multiple different reasons?

Having passengers in your Electric Vehicle will not drain the battery. There are multiple other factors that will result in draining your battery quicker than usual but having one or more passengers is not one of them.

Having extra passengers in any car should be normal for a vehicle and the vehicle battery life should not be altered by a little extra weight. Cars are designed and built to withstand weight in the driver’s seat as well as passenger seats. Why else would we have passenger seats? Read on below to find out what will drain your battery.

What Will Drain Your Electric Vehicle Battery?

A dead battery can be a little more than frustrating so that’s why we always recommend listening to your car and what it needs to avoid any unnecessary and flat situations.

Here is why your battery might be draining quicker than it should:

Extreme Temperatures

Extreme temperatures can alter the way your battery works and charges. In harsh weather conditions, too hot or too cold your electric vehicle’s battery might not be getting the sufficient charge it needs to run for the ample range it should.

Consider installing your power grid in a weather-proof area where the harsher weather conditions shouldn’t affect how it charges your vehicle.

Not Driving Regularly

Just like that of a combustible vehicle, you need to be driving your car on a regular basis. The longer your car is left unattended and undriven the quicker the battery drains while sitting there.


Who would have thought there was such a thing as over-charging? Have you ever had a laptop that you kept leaving on charge for too long and found that the battery never really lasted that long? The lithium-ion battery does not like to hold too much charge.

Consider setting the power grid to charge to 80% instead of 100% occasionally.

Letting Your Vehicle Battery Drain

Rechargeable batteries aren’t designed to be drained below a certain level. In the case of electric vehicles, it’s usually about 20%.

When your EV has 20% charge left, you might want to consider charging it up to avoid any discharge strain that can cause your EV battery to deteriorate quicker.

Don’t Overuse a Fast Charger

You can degrade your battery quite quickly if you constantly use a fast charger. Keep up to date with how often you charge your vehicle and when it’s due for a new charge so that you don’t need to continuously rely on a fast charger.

The faster the charge, the hotter the battery becomes and when batteries get too hot they start to degrade. This results in the battery never quite reaching its full charge potential.



Having added passengers in your car will not result in draining your battery any quicker unless they leave a door open upon leaving the vehicle. Consider the other ways in which you might drain your electric vehicle battery and avoid them where you can to ensure the longevity of your battery and a much larger range in mileage.
