If you drive manual cars, driving electric cars might be a little different. This is because a single electric car gear system powers most electric vehicles and they don’t have gear shifters.
Even though electric vehicles have some similarities with their commercial equivalents, when it comes to powertrains, EVs are totally different.
Electric cars don’t have a gear stick or gear lever. Manufacturers designed electric cars with an acceleration pedal and brake pedal. Unlike conventional vehicles, the accelerator isn’t the gas pedal in EVs because these cars don’t run on fuel.
Stepping on the accelerator pedal will not shift gears. Let’s go through the electric vehicle transmission system and the electric car gear system in detail.
The electric vehicle transmission system
Every car has a transmission. Transmission diffuses power and torque to the engine. When it comes to electric car working, they have automatic transmissions.
One of the most unique features of EV acceleration is that it’s rapid, quiet, and smooth.
The fuel source is the major difference between electric and petrol vehicles. When you press an electric vehicle accelerator, an electric current is sent from the battery to the electric motor.
A single alternating current motor is fixed to the gearbox in most electric cars.
Different from internal combustion engine powered cars with multiple gears, electric vehicle transmission has a single-speed gear reduction unit. This is because all the gears are connected and turn at the same time.
The car’s RPM is reduced to a reasonable rate because of the single-speed electric car gear reduction unit. However, electric cars don’t have a clutch, and the speed isn’t powered by engaging and disengaging the clutches or shifting gears.
The AC motor on electric cars can spin as high as 18,000 RPM or more. This enables EVs to give a massive 30-40 mph torque at high speed. With electric cars, the rotational forces go rapidly from the gearbox to the wheels resulting in a smooth and quick acceleration without the need of shifting gears at different ranges for speed transition.
The absence of multiple gears hampers friction (wear and tear) from engaging and disengaging clutches.
According to manufacturers, for electric cars, the efficiency of the motor transmitting power to the wheels is about 89% to 96%. Whereas, in ICE vehicles, it is only about 14% to 26% efficient.
How many gears do electric cars have?
As mentioned above, electric cars don’t have gears or clutches. They don’t have multi-speed transmissions like their conventional counterparts powered by fuel or diesel. Instead, EVs feature a single-speed gear (also known as a gear reduction unit) that produces a higher level of RPM than conventional vehicles powered by ICE engines.
In a minute, an ICE-powered car can go up to 4,000 to 6,000 RPM, whereas, in a minute, EVs can achieve as high as 18,000 miles.
The internal combustion engine generates torque to speed up the car at different speeds depending on the gear level. Therefore, for ICE cars, the engine must maintain the required level of torque and power for the vehicles to accelerate quickly.
On the contrary, electric cars generate instant torque at a low speed (even below 1,000 RPM). The torque reduces as the revolutions per minute increase. Therefore, it is better to maintain a low RPM of around 2,000.
Though EVs have a single-speed transmission and just one gear. However, some latest EVs are powered by multiple gear-speed transmissions. Here are some pros and cons of buying electric vehicles.
That is all about how many gears an electric car has. Thanks to low emissions, ease of use and quick acceleration, many people prefer driving electric vehicles. If you are looking to drive an EV, go through this list of used cars for sale in the UAE including electric cars.
FAQs
Do electric cars have manual gears?
Electric cars do not have manual gears or clutches.
Why do electric cars only have one electric car gear?
Electric vehicles don’t have clutches, that’s why they don’t require gears. Most manufacturers design EVs with one gear, usually known as the single-speed transmission. This is because EVs can achieve high RPM on low and high torque.
Can electric cars shift gears?
Electric cars don’t have an engine, they are powered by a battery, therefore, gear shifting isn’t required to run the car. Most electric cars have a single speed transmission gear system and some auto manufacturers have introduced multiple gear-speed transmissions, whereby, the rear wheels use the two-speed transmission and the front wheels use the single-speed transmission.
