The use of industrially produced electric cars has increased significantly in the last 13 years. The year 2010 can be considered the initial stage of mass production of electric cars when the manufacture of the Mitchubishi I–MiEV and the Nissan LEAF was started. For modern electric cars, the battery mass can reach up to 770 kg. If the electric car is intended for long distances, the large mass and capacity of the battery is justified because it is put to good use. If the electric car is mainly used in urban driving mode, an increase in the mass of a heavy battery can reduce the range or energy consumption per km. To identify the effect of change in the mass of an electric car on the amount of electricity consumed, experimental studies were carried out with a converted electric car Renault Clio. A 10 kWh battery with a mass of 125 kg was used for the electric car. A road experiment was conducted in Jelgava city on a route that included streets of different traffic intensity with two different loads for the electric car. With an additional load for the electric car, the mass increase was simulated as if the mass of the battery was doubled. The road experiment showed that on the same city route, an increase in the mass of the electric car increased energy consumption by 5.8%, which in turn increased operating costs.
