General use of electric machines in an apartment building

The problem

A large number of cars leads to air and environmental pollution. Parking space is needed, which could be used for a park or green space. A large amount of non-renewable carbon fuel is consumed. The transition to electric vehicles partially solves these problems, but if everyone has their own electric car, the problem of parking and charging will remain. Each family will have to spend money on maintenance.
The idea

We propose the idea of sharing one or more electric vehicles among residents of a single building.
The prototype

We created a prototype using an ESP32. When the car is connected to a charging station, a light comes on and it charges.
The result

This demonstrates how to charge an electric car.

What we learned

Use of electrical energy for motor transport.
