If the gasoline engine needs oil to operate, but the electric motor only needs electricity to operate
Traditional gasoline- and diesel-powered cars require oil to lubricate many of the moving parts in the engine as well as the drivetrain. The pistons, valves, and other moving parts of the engine need to glide smoothly past each other at very high speeds, so oil is added to the engine to lubricate these close interactions.
Adding oil to the engine will keep the engine running without overheating. After a while, microscopic metal particles accumulate in the oil from all the contacts in the engine, so it is necessary to drain the old oil and add new oil to keep the engine running better. If you don’t change the oil, the engine will quickly wear out, lose power, even have to remove the engine (additional engine) for repair.
But in contrast, in an electric car, none of the above happens. Because at the most basic level, electric cars move using batteries and electric motors. There are no engine pistons, valves or moving parts that require lubrication, so frequent oil changes are not necessary for electric vehicles.
The powertrain of the most popular electric vehicle has eliminated up to 20 moving parts compared to an internal combustion engine vehicle. Therefore, maintenance will be less and simpler, but there are still parts in electric cars that need regular maintenance.
Heat is a big problem for electric cars, just like internal combustion engines. To manage the heat released from the lithium-ion battery, a coolant is required.
All coolant levels for the battery, cabin heater, and car starter must be checked. While cabin heating can be a minor issue, the other two components are critically important.
Electric cars caught on fire in the past, possibly as a result of owners letting the batteries overheat. So keeping the coolant level high is best practice.
Tesla models and most other electric vehicles don’t use a transmission, so the concept of gear oil doesn’t matter.
However, Porsche’s electric Taycan has made a new breakthrough by introducing a two-speed transmission that needs to be serviced with transmission oil. Therefore, if there are many electric vehicles with gearboxes produced in the future, users will have to pay attention to the maintenance and replacement of transmission oil.
This detail is rarely required, instead of the regenerative braking system on electric vehicles, which reduces brake wear by converting the kinetic energy of the moving car into electrical energy for the battery.
Basically, the regenerative braking system is the main means to slow down the car and reduce brake pad wear.
The regenerative braking system on electric vehicles is an important part of power generation equipment. However, it is necessary to ensure that the brake system is working properly, which is very important because in addition to generating power, this is also a key element to slow down the vehicle, so brakes need to be checked regularly.
Software inside the car
Software is a key component of power management systems in electric vehicles and there is a similar engine management system that applies to all modern internal combustion vehicles and will have to be updated at dealerships. However, Tesla has set a new precedent by updating its software remotely. Sending over-the-air updates provides new features and improved performance enhancements for battery management.
In addition to the above, parts such as door hinges that need to be lubricated and properly inflated tires are the same things that need maintenance as an internal combustion engine vehicle. In addition, there are still concerns that car owners need to keep in mind.
Long-term electric vehicle ownership and maintenance
Owning a car normally lasts about 3-10 years. Maybe car owners don’t plan to keep a car for 10 years, but if they do, regular car maintenance is a big need. This is where things start to get expensive for electric vehicles.
About once every seven years it is necessary to “generally clean” the cooling system by draining, cleaning and filling all the water lines of the car. The most worrying thing is that the batteries in electric vehicles can be replaced in about 12 years if used stably. The replacement cost is about 1,000-6,000 USD, similar to replacing the internal combustion engine in a regular car.
Experts say that the life cycle of electric vehicles could reach an average of nearly 500,000 km in the next few years.
