Why is it so hard to charge electric vehicles on the road?

Almost 6 percent of cars sold in the US last year were electric, topping 800,000 vehicles.

One in five EV drivers didn’t charge their vehicle during a visit to a public charging station last year, mainly due to outages or malfunctions.

White House wants to nearly triple that number by building a national network of 500,000 EV chargers.

In 2021, there will be 1.4 million electric vehicles registered in the US, not including plug-in hybrids.

Electrify America said the company is still investigating its charging problems.

Used EV owners may be on their own if something goes wrong with their vehicles.

DC fast chargers provide a huge amount of power directly to the battery, topping it off in as little as 20 minutes.

DC chargers require sophisticated hardware to connect to the grid, adding to their cost.

Each manufacturer has different needs, so communication between the car and the charging station is critical.

Electrify America currently operates the largest public EV charging network, with more than 800 stations.
