EVs will charge themselves in the future or they will not help reduce carbon fuel powered grids... EVs will only need one battery or 2 to start them and begin putting them in motion... Alternator systems running via belt driven off the front and rear axle will start powering vehicles when they are put in motion... A small amount of power used to start the EV and start it in motion will be recharged by the same alternator system that will power the car... It is so simple but will not cost untold billions... So wait for the real EV evolution to be sincerely needed from the decline of fossil fuels... And save your money... So we watch...LJ
