The charging station recommendation models are getting attention for a wide acceptance of EVs in the market.

Slow charging results in lower battery temperatures and enhances the longevity of the battery and is therefore recommended by Ionic when possible. As an example, using a 100Ah battery, you would slow charge it by using a 10A charger and the battery would take about 10 hours to charge. You would fast charge it by using a 45A charger and it would charge in a little over 2 hours to
