The car has an electric motor has characteristics that are considered unusual and also interesting when compared to vehicles that are considered conventional.
The electric motor can act as energy storage stations and the cars are loaded in the periods in which power consumption is low as at dawn, because that is the period in which energy consumption is lower.
And the use of the electric motor can return the electricity that was left during the day to use as it connects to your load center and integration is managed in a process network called smart grids.
The electric motor efficiency comes to be 90%, but when compared to the combustion engine efficiency drops to 40%. One must take into consideration all the factors involving the electric motor efficiency, because the electric motor may or may not be considered effective to bring benefits to the environment. Recharging the electric motor can be done soon with renewable sources. https://www.mrosupply.com/bearings/radial-ball-bearings/320022_6306-2zjem_skf-bearing/
