Do electric vehicles get overheated?

Electric cars have indeed had benefits that internal combustion engine cars do not have. It is only fair to wonder, do electric vehicles get overheated? Do they need a cooling system in the fast place? You are not alone. This is why am here to answer some of the technical questions you might be having about electric cars. They are relatively new in the market and therefore no much information is available. You ought to know as much as possible before buying one lest you get into trouble sometimes later.

So, do electric vehicles get overheated? Yes, they do get overheated but not as much as the internal combustion engine cars. Most of the heat comes from the battery when it is in use.

Much of the energy generated by an internal combustion engine is wasted in form of heat. This heat is released into the environment. The less efficient a vehicle is, the more energy is wasted in the environment. You may have realized that exhaust gas is hot. This is some of the energy going to waste inform of heat. Do electric cars have exhaust? No, they do not have exhaust since they use the battery to run; they do not use gasoline.

Do electric cars have a cooling system then?

Since we have established that electric cars get overheated, do they have a cooling system? Electric cars have a cooling system. perhaps EVs` cooling system is more sophisticated than that of an ICE. The electric car`s cooling system is controlled using a computerized system to ensure the battery is safe. The battery is the most expensive part to replace. It is important to take care of it.

The cooling system is designed to cool two major things. The first thing is the car battery.  Thermal stress affects lithium-ion batteries reducing their life span. The second thing is the motors.  Since motors can spin far faster than an internal combustion engine, they get overheated. The heat is due to friction as well as heat generated by the coil due to wire resistance.

The cooling ensures that everything is working as it was originally designed.  However, you ought to know that not all cooling systems work effectively. Electric car cooling system has to be regularly maintained.

Do electric cars heat up fast?

How hot can an electric car get?  Do they get heat up fast? Well, there are many reasons why your electric car can get overheated. Those are the reasons that determine how fast and how hot it can get.

The first thing that affects how fast and how hot your EV gets is the age of your car. Continued use of your car can lead to degrading of most vital parts. For instance, the lithium-ion battery degrades naturally as it grows old. One sign of aging is heating up excessively. The older it gets the faster it gets overheated.

The second thing that determines how fast and how hot your electric car can get is how you maintain it. If you maintain your electric car poorly, it will always get overheated very fast. You need to follow the recommended check-up schedule for your vehicle. You can also do it more frequently than is recommended by the manufacturer. With proper maintenance, you prolong how long your electric car can last.

How long does the battery last then?

How many years will an electric car last?  8 years. The item that gets worn out first is the battery. Therefore, your electric car can last as many years as your battery. You can extend the life of your electric car by changing the battery. However, I would not recommend that. I would buy a new car.   Electric car batteries are very expensive to replace. Besides, new models feature better attributes than the previous ones.

During the check-up you can have the oil changed! Wait, what? Do electric cars use oil? Do they need oil changes? Yes, electric cars use oil. However, not in the sense the regular cars do. And yes, you need to change the oil regularly.  The oil is used in your electric car cooling. You see, electric cars use oil.

Electric cars do need coolants to prolong the lifespan of the battery. Furthermore, there are many electric components since most of the new models are computerized. Such components need cooling as well. Instead of using a fan that draws power from the battery, oil is a better alternative.

You do not have to worry about your EV getting hot. It is natural for anything using energy to get hot. You just have to regulate this by using coolants.

Do electric vehicles have a cooling system

Electric cars not only do they have a cooling system but also need coolants. You have to understand that your battery requires both cooling and heating. Heating now? Yes, you have to keep the battery at a regular temperature to maintain the range. Doesn`t get too cold in winter?  Low temperatures affect how batteries work.  The electrolyte may freeze rendering your battery useless and your car altogether.

You will find a computerized system called battery management system (BMS). This is the system that maintains required battery temperatures at all times. It prevents your battery from getting too cold or hot. You can also keep your car plugged into an outlet to keep it warm.

The cooling system also works using the same principle a regular car use. You have to go for a check-up to ensure that the coolant level is maintained to the required level. Failure to do so will cause damages to your car.

Cooling the interior of an electric car is not an issue. Just like a regular car uses an AC, they use AC as well. Nothing special.

Why does your electric car overheat?

Since you have the answer to do electric vehicles get overheated, let us discuss what other factors can cause your car to overheat. Other than poor maintenance, let us look in detail at why your car may get overheated.

  i.  Charging habits

How often do you charge your electric car per day? Charging it more than 3 times may cause an overheating. In my article on electric cars charging themselves we saw Even when using a wireless charging system, charging EVs more often cause overheating.

The place where you charge you can also determine how hot your car can get. When you are in an open area, the temperatures from the sun outside increases that of your car. Most manufacturers recommend charging EVs indoors to prevent overheating. Remember high temperatures in the components do not increase due to the use only. The weather conditions can cause the battery to become too hot, motors as well. Other components get affected as well.

ii. Driving habits can cause overheating

Continuously drawing power from the battery can cause it to overheat. Also, you continuously keep driving very fast, the motors and other components get very hot, very fast. So, what would I recommend to prevent this? My advice is that you take breaks from time to time. After covering 100 miles or 220 kilometers, you should take a break.

iii.  Where you are located

Surprisingly, the outside temperatures can affect the temperature of the components inside your EV. It can be worse if your battery is poorly insulated.  A review by some of the experts indicated that the coolant gets heated by hot air from outside. Consequently, the coolant heats your battery. It is unexpected but it does occur.

Regions that are located near the equatorial region have this type of problem. For instance, we have this problem when we visit Kenya and India. Besides, summers can get very hot. This causes the battery to be hot.  Keep your car under the shade.

 iv.    Battery management system

BMS is important and its efficiency affects how your battery can get. I once had hardly effective BMS. It led to serious overheating problems. I had to change the coolant more often. I had to go for a new car altogether.

How can you manage to overheat in your EV?

We have established that it natural to get your car hot. The problem is if it gets extremely hot. This is why I would like to recommend some of the things you can do to keep your car at the required temperature.

    i. Keep your car under the shade when you park

Do electric vehicles get overheated,  is an interesting topic to discuss. Why so? The simplest practices can help you to avoid overheating.  For instance, keeping your EV under shade can prevent overheating due to the direct sunlight and the surrounding air. This is why you ought to be careful where you park your car. You do not have to worry during winter.

Since low temperatures affect your battery as well, when you park during cold weather ensure the charge is connected. It keeps the battery management system working and thereby warm. It can also help cool your car if it is too hot.

  ii.            Drive carefully

It is okay to enjoy a fast ride especially when your journey is long. You can keep your car safe by stopping intermittently.  I would recommend once every 100 miles. It would keep both the motor and the battery cool.

There are many modes you can also choose while driving. The ludicrous mode optimizes the performance while giving the speed you need. It is very useful when driving long distances.

iii.  Plan how you charge your Electric car

You might have realized it requires up to three or more hours to charge your battery to capacity. Well, it takes almost half that time to reach about 80%. So, if you are not going for long-distance that ought to be sufficient.  Furthermore, since you might already know the range of your car, it is recommended to have your battery between 20% and 80%. So, plan how you will be charging your car.

How will I know that my battery is too hot?

Remember we talked about the battery management system? That is the one that is supposed to alert you when the temperatures exceed what is indicated.

If you receive a warning, stop the EV for sometimes to give it time to cool off.

The other way to tell is by evaluating how the battery is performing. If It is not giving the ranges necessary; it could be because it is becoming overheated. If, the battery is unable to sustain a charge for a long time. This is another indication there is overheating. So, before you dump your battery or car for another one, check for overheating signs first.

Electric car cooling system

Batteries are very expensive. Therefore, it pays to know as much as possible about them. It is necessary to know that a battery can cost almost as half of a complete car.

The EV battery is supposed to be operated at  C. If you happen to operate it at  C, you reduce the service life by almost a half.

Some people go for air cooling. This is a bad idea. Air absorbs very limited heat from the battery. Furthermore, for the air cooling to work well, there has to be enough space around the battery for air to pass freely.

There is the option of using water. Water has better heat absorbing properties but it has its downside as well. While the air used for cooling is limitless, the water has to be contained somewhere and itself has to be cooled by air at some point.  Let us now explore more options available for your electric car

  i.  Indirect liquid cooling

Have you ever seen how water-cooling works in a regular car? If you have, good for you because it is the same principle used in EV. The water in pipes is made to move surrounding the battery and absorb all the heat away from the battery.  Any coolant to use in this manner can be used in the ICE engines as well.

I have found out that 99% of the coolant you will find suitable for this use is polyglycol.  According to an expert review, the 1% addictive is what makes the difference. It defines the good and great when it comes to cooling performance. Some liquids are corrosive, including water. It is, therefore, very necessary to take care lest the whole system is replaced in the future.

The 1% additives ought to include antifreeze and corrosion inhibitors

  ii.    Direct liquid cooling

This is where your battery is directly exposed to the coolant. The basic properties of such coolant ought to include low or zero conductivity. All the internal combustion engines have never used this system extensively.

Why should the coolant fluid be of low conductivity? Electrons do flow throughout the battery. An exposure to electrons from other places can lead to one of two things; a failure or explosion. De-ionized water has low conductivity and can be used as a direct coolant. Direct cooling is still not fully developed though the manufacturers are working on it.

Final thoughts on do electric vehicles get overheated

The pressure has all been mine while discussing with you “do electric vehicles get overheated?”. You deserve the best the automotive industry has to offer when it comes to EVs. Knowing how to maintain an electric car is very important. The benefits of electric cars are numerous besides the low cost of operation. However, the cost of neglecting your car is equally high. Manufacturers offer about 8 years of guaranteed battery life. With proper maintenance, it is possible to extend this service life significantly.

I hope electric vehicles become more efficient so that we can do away with petroleum products. Global warming has been a serious threat to the world we live in.
