TankTwo, a New York-based start-up has developed a new electric vehicle battery pack that claims it can give drivers a full charge in under three minutes. The company is working with the University of Michigan to develop and test its battery, which will be used on an upcoming prototype vehicle. This means that if a car needs to re-charge quickly, say in under three minutes, it could visit a service station equipped with TankTwo systems, and simply take out the “egg” batteries, replacing them with fully charged ones. The reason for the speed is that the batteries don’t need to be wired together, they just need to be touching each other in a box, as illustrated here. Furthermore, the company boasts that these batteries will be cheaper, longer-lasting, and could even have more capacity at resale allowing for potential resale profit.

The company uses what is calls “string batteries,” which look like a lot of little metallic eggs in a box, these use contact surfaces to route power in and out through the pile of batteries.
