You know how smartphones have a battery accessory? Well, there is a lot of electrical cars that could use a little back-up battery.

What you are seeing on the back of this car is an EP Tender, and it is a generator on wheels. It is connected to the car’s battery via a cable, and the generator switches on and feed the battery its necessary juice. It is capable of 22kW energy while the car is traveling at 80 miles per hour.

This is pretty interesting, and considering that I have no idea if our roads are set up for electrical vehicles to take road trips. I mean, isn’t there something set up for electrical vehicles?

So, I wonder if we will be seeing more of these on vehicles in the future. I guess that depends on whether or not there are more electrical vehicles in the future.
