What fluids does an EV car use?
If you drive an EV, you can officially say goodbye to oil changes, as electric cars do not use oil. They do, however, require brake fluid, coolant, and transmission fluid changes. Take a moment to learn more about maintenances requires for EVs like the Jaguar I-PACE.
Battery Coolant: Battery coolant, also known as thermal management fluid, plays a crucial role in maintaining the optimal temperature of the EV’s battery pack. It circulates through a cooling system to prevent the battery from overheating during charging or discharging. Maintaining the right temperature helps prolong the battery’s lifespan and ensures efficient energy storage.
Brake Fluid: Like conventional vehicles, EVs have a braking system that relies on hydraulic brake fluid to transmit force from the brake pedal to the brake calipers. While some EVs use regenerative braking to recover energy, traditional friction brakes are still used in most cases. Brake fluid ensures that the brakes function effectively and consistently.
Coolant for HVAC System: EVs typically have an air conditioning (A/C) and heating system that requires a separate coolant or refrigerant fluid to regulate cabin temperature. This system operates independently of the battery coolant and ensures passenger comfort while driving.
Windshield Washer Fluid: While not unique to EVs, windshield washer fluid is used to clean the windshield, headlights, and rear window. EVs, like any other vehicle, need this fluid for visibility and safety.
Transmission Fluid (for some EVs): Some EVs have a transmission or gearbox, especially those with a multi-speed transmission. These transmissions may require a specific type of transmission fluid, although many EVs use a single-speed transmission that does not require traditional transmission fluid.
Do electric cars need steering fluid?
Electric systems do not require power steering fluid to work and only draw power when needed, making them more fuel efficient than hydraulic systems.
No, electric cars do not require steering fluid, as they use electric power-assisted steering systems (EPAS) instead of traditional hydraulic power steering systems found in many internal combustion engine (ICE) vehicles. The absence of hydraulic power steering eliminates the need for steering fluid in electric cars.
Here’s how electric power-assisted steering systems work and why they differ from hydraulic power steering:
Electric Power-Assisted Steering (EPAS):
EPAS is a modern technology used in electric cars and many conventional vehicles. It replaces the traditional hydraulic power steering pump and fluid with an electric motor and sensors. Here’s how it functions:
Electric Motor: An electric motor is integrated into the steering column or steering rack of the vehicle. This motor assists in turning the steering wheel and provides power assistance to the driver.
Sensors: Sensors monitor various factors, including vehicle speed, steering wheel position, and driver input. These sensors adjust the level of power assistance based on driving conditions. For example, at higher speeds, less power assistance is needed, while at lower speeds or during parking maneuvers, more assistance is provided.
Energy Efficiency: EPAS is highly energy-efficient because it only consumes power when the steering assistance is required. In contrast, hydraulic power steering systems continuously run a hydraulic pump, consuming energy regardless of whether steering assistance is needed.
Do electric cars need brake fluid?
Electric cars do not require oil to run properly. That said, they do require transmission fluid, coolant, and brake fluid.
Yes, electric cars (EVs) do require brake fluid, just like traditional internal combustion engine (ICE) vehicles. Brake fluid is a critical component of the braking system, and it serves several essential functions in both types of vehicles.
Here’s why electric cars, like all vehicles, need brake fluid:
1. Hydraulic Brake System: While EVs use regenerative braking to recover energy during deceleration and braking, most of them still have a hydraulic brake system as a backup. This hydraulic system is responsible for the vehicle’s traditional friction brakes (disc brakes or drum brakes) and is used when regenerative braking alone is insufficient for slowing down the vehicle or coming to a complete stop.
2. Brake Fluid Transfer: Brake fluid is a non-compressible hydraulic fluid that transfers the force applied to the brake pedal by the driver to the brake calipers or wheel cylinders. When the driver presses the brake pedal, brake fluid is pressurized, causing the brake pads to squeeze against the rotors (or brake shoes to press against the drums), creating friction and ultimately slowing down or stopping the vehicle.
3. Heat Dissipation: Brake fluid also serves as a heat transfer medium. During braking, kinetic energy is converted into heat due to the friction between the brake components. Brake fluid helps dissipate this heat to prevent the braking system from overheating and losing its effectiveness.
Do electric cars need coolant?
While EVs have fewer maintenance requirements than gasoline vehicles, primarily in that they don’t need oil changes, they do need their coolant changed on a regular basis.
Yes, electric cars (EVs) do require coolant, but it serves a different purpose compared to the coolant used in traditional internal combustion engine (ICE) vehicles. In EVs, coolant is primarily used to regulate the temperature of the vehicle’s battery pack and sometimes the electric motor and power electronics. Here’s a detailed explanation of why coolant is necessary in electric cars:
One of the critical components in an electric vehicle is its lithium-ion battery pack. These batteries are sensitive to temperature fluctuations, and their performance, safety, and longevity depend on maintaining an optimal operating temperature range. Here’s how coolant is used for battery cooling in EVs:
Battery Thermal Management: Electric cars are equipped with a thermal management system that includes a liquid coolant. This coolant circulates through channels or pipes around the battery cells to regulate their temperature. It helps prevent the battery from overheating during charging, discharging, or fast driving, which can degrade the battery and reduce its lifespan.
Temperature Control: The thermal management system, which includes a radiator, pump, and heat exchangers, works to dissipate excess heat generated by the battery and maintain a consistent temperature. This ensures that the battery operates efficiently and maintains its capacity over time.
Cold Weather Operation: Coolant can also be used to warm the battery in cold weather to maintain its performance. Some EVs have electric heaters or resistive elements in the battery pack that use coolant to warm the battery to an ideal operating temperature when driving in frigid conditions.

Tesla owners should refer to the manufacturer’s recommended maintenance schedule in their owner’s manual to stay informed about when fluid-related inspections and replacements are necessary.
Do electric cars need oil or water?
Electric cars use completely different drivetrains, so you will never have to worry about routine oil changes that are necessary for traditional cars. Though your electric car does not need oil, it requires a routine check on these 3 fluids in EVs; coolant, brake fluid, and windshield washing fluid.
Electric cars, in general, do not require engine oil, as they do not have traditional internal combustion engines. However, they do use coolant, which is primarily water-based, but it serves a different purpose than coolant in traditional gasoline or diesel-powered vehicles.
The coolant used in electric cars is not the same as traditional engine coolant (antifreeze) used in ICE vehicles. It’s specifically designed for the battery thermal management system and may include additives to improve heat transfer and prevent freezing or boiling under extreme conditions.
Electric cars do not require engine oil because they do not have internal combustion engines. Instead, they use water-based coolant for battery cooling, which is essential for maintaining the proper temperature of the battery pack. This coolant is critical for the safe and efficient operation of electric vehicles and is a key component of their thermal management systems.
Is there oil in electric cars?
The short answer is no. Electric cars do not need motor oil as they don’t have the conventional internal combustion engine with all the moving parts. Plug-in hybrids (and hybrids) still require traditional maintenance as they still employ an ICE in combination with an electric motor to increase efficiency.
No, electric cars do not contain engine oil because they do not have traditional internal combustion engines like gasoline or diesel-powered vehicles. Electric cars are powered by electric motors that use electricity to generate motion, eliminating the need for engine oil. This fundamental difference is one of the key distinctions between electric cars (EVs) and internal combustion engine (ICE) vehicles.
Instead of engine oil, electric cars use various other fluids, primarily coolant and brake fluid, for different purposes:
1. Battery Coolant: The most significant use of fluid in an electric car is for battery cooling. Electric vehicles are equipped with lithium-ion battery packs that can generate heat during charging and discharging. To maintain optimal battery performance and safety, a coolant system circulates coolant (usually water-based) through the battery pack. This coolant helps regulate the battery’s temperature, preventing it from overheating, which can degrade its efficiency and lifespan.
2. Brake Fluid: Electric cars, like all vehicles, use hydraulic brake systems for their traditional friction brakes. Brake fluid is a crucial component of this system, facilitating the transfer of force from the brake pedal to the brake calipers or wheel cylinders.
