The battery capacity is essential in EV autonomy.&amp;nbsp;&amp;nbsp;Depending on the automotive OEM&amp;nbsp;a

The battery capacity is essential in EV autonomy.  Depending on the automotive OEM a fully charged EV battery can provide between 20 KWh (160 km for Nissan) and 85 KWh (480 Km for Tesla).

  • Vehicle's built-in charger: charges up to 43 kW at 230 VAC single-phase / 400 VAC three-phase.
  • External charger: converts AC to DC current and charges up to 120 kW.

Besides charging stations connected to the electrical grid based on fossil-fuel or nuclear power the industry is looking as well into renewable electricity for charging stations like:

  • Solar Power Automotive Recharging Station
  • E-Move Charging Station
  • Wind Powered Charging Station
