Currently, the typical driving range of an EV is between 300 and 400 miles.

The actual number depends on various factors, including the types of electrical components and operating time.

One of the big concerns on a rainy day is how much energy the windshield wipers require.

How much do they also impact the driving range?

Although the energy used by electric vehicles is considerable, it is dispersed over multiple pieces of machinery.

A mathematical formula is used to determine the amount of energy that each component consumes.

Each electric vehicle will list its estimated kWh/100 miles energy consumption and efficiency.

For instance, the Tesla Model 3 uses an average of 23.7 kWh/100 miles for one hour of use.

Usually, a wiper motor consumes less than 50 Watts of power.

However, the majority of these wiper blades would operate on far less. 

For this, 3–4 kilowatts per hour of energy is required to power everything.

This equates to a 5.16-mile reduction in the battery's practical driving range.

Therefore, turning off the wipers would only save you.006 miles, which is not very much.
