Land transport produces a large amount of CO2 emissions. That is why there is an effort to introduce vehicles with direct zero emissions. Battery electric cars have zero tailpipe emissions and run solely on electricity.

However, widespread acceptance of EVs is currently dependent on a convenience of their charging and the availability of charging infrastructure.

According to the U.S. Department of Energy, 80 percent of EV charging happens at home due to the convenience and low cost of residential charging. The rest of EV charging takes place at public charging stations.

The charging modes are standardized in IEC 61 851-1 and SAE J1772, according to the type of input current (AC or DC) and the power level.

Please review the table that briefly describe both charging modes. We can see the result in the attached picture.
