The demand for electric cars is increasing drastically around the world. With many benefits, electric cars also require less maintenance than conventional cars. However, when it comes to car fluids, EVs require a handful of them. That said, we have prepared a list of EV fluids that are still required for such vehicles and how they affect the car’s performance.
What Fluids Do EVs Need
The maintenance of electric cars is different from their petrol-powered counterparts. Electric cars do not require oil due to the absence of a combustion engine but other types of fluids to keep up a top road performance.
We have prepared a list of what essential car fluids that evs still need to use and how they help in the working of an electric car.
Battery Coolant
Electric motors generate heat, just like parts of an internal combustion engine, and require a cooling system to prevent overheating. A coolant is an EV fluid that prevents the overheating of electrical components having high voltage and generates even more heat during charging. EVs use a type of coolant called propylene glycol which is circulated through the battery and other components with the help of an electric pump. When it is circulated by the motor and battery pack, it absorbs and dissipates the excessive heat.
You can also charge your electric car with bidirectional charging. This charging technique uses an AC-to-DC inverter for the power conversion process.
This coolant is different from the fluid used to prevent overheating on petrol engines. Besides, the coolant levels must be checked regularly by a professional mechanic. If it is neglected, it can lead to different problems in electric car batteries.
Transmission Fluid
Electric vehicles do not have traditional transmissions that require transmission fluids. However, electric cars do have gears, a single-ratio gearbox with a direct-drive transmission. This part of the vehicle requires EV transmission oil. This lubricant used in EVs is often a synthetic oil that is designed to handle high torque and temperatures generated by the electric motor.
Additionally, it is crucial to follow the manufacturer’s recommended maintenance schedule and use the specified lubricant to ensure optimal performance. A trained technician must be addressed to fill or replace this type of EV fluid.
Thermal Fluid
Power electronics play an important role in the working of electric cars. That said, several components generate heat such as the battery and motor. If these components get too hot, it damages them and reduces their lifespan. Therefore, it’s crucial to regulate their temperature.
To cater to this, thermal fluids, also known as heat transfer fluids, are substances that are designed to absorb and transfer heat. In electric cars, they are used to cool the battery and the power electronics. They can also be used to heat the cabin during cold weather. Several types of thermal fluids can be used in electric cars, including water, glycol and refrigerant fluids. Such EV fluids maintain the car’s operating temperature and are an important tip for electric car maintenance.
Windshield Wiper Fluid
A windshield wiper fluid in electric cars is essential for maintaining good visibility while driving. The windshield wiper fluid in electric cars is formulated differently to avoid damage to the electric motor or battery components that are often located near the windshield.
Nowadays, many electric vehicles come equipped with energy-efficient windshield wiper systems that require this fluid to work. However, one must consider the specific needs of their electric car when selecting and using this fluid.
Steering Fluid
Most electric vehicles do not use power steering fluid due to the use of electric power steering systems. However, some electric vehicles, such as hybrid models, may still use hydraulic power steering systems. In these vehicles, power steering fluid is used to help transfer power from the steering wheel to the steering rack or gearbox. It also helps to lubricate and cool the components of the power steering system.
Brake Fluid
Brake fluid is a critical component in any vehicle, including electric cars. In such cars, the brake system is slightly different from traditional combustion engine vehicles, but the principles of the car brake fluid remain the same. It is used to transfer the force of the brake pedal to the brake callipers, which then apply pressure to the brake pads to slow down or stop the vehicle.
It is important to regularly check the brake fluid level in an EV. One must also ensure that it’s maintained at the correct level to ensure proper braking performance and safety. If the brake fluid level is consistently low, it’s essential to identify the root cause of the issue as soon as possible to prevent further damage to the brake system. Some common causes of low brake fluid in electric include:
- Wear and tear of the brake lining.
- A leak in the hydraulic system.
- Faulty brake components, such as a stuck brake calliper or a faulty brake master cylinder also cause the brake fluid level to drop.
- Brake fluid can also evaporate over time, especially in high-temperature conditions. This can cause the brake fluid level to drop, reducing braking performance.
- Overfilling of the brake fluid reservoir.
Lubricants
Lubricants play a crucial role in the smooth and efficient operation of an electric car. They include electric motor oil and gear oil along with the remaining EV fluids mentioned above. These lubricants help in reducing friction among car parts, prevent corrosion, remove contaminants and seal gaps between components.
These are the different EV fluids that are required for smooth running and safe handling of the vehicle. Therefore, when you opt for an electric car from the used cars for sale in the UAE, ensure that all the fluids are at an appropriate level for smooth operation.
