How Batteries at Charging Locations Could Charge Every EV Faster

charging infrastructure could be more consequential for the introduction of electric cars as an innovation in the cars themselves: More places to charge faster can play an important role in drivers’ experience and perception of EVs. But creating a massive network with numerous fast chargers isn’t a trivial effort, as EV haters like to point out: it’s a big building project almost in the area of ​​the motorway network This can exceed the power available in many areas, regardless of how many cables you use or how many chargers you connect to them.

“The question isn’t really about utility infrastructure,” he said John Tuccillo, Head of Global Corporate and Government Affairs at ADS-TEC Energy. “The question really is the available power” that can be delivered through all those lines and substations. If it’s not enough to support a large number of fast-charging outlets, malls, gas stations and other partners will be stuck trying to balance their slower Level 2 charging technology with a rising consumer expectation of a quick grocery-pickup visit, a Order curb online or just a Slurpee. Relying on drivers spending longer than necessary on errands to allow for slower load times is a losing bet.

ADS-TEC promotes a technology called battery buffering that it can increase grid power at the charging location by using special batteries installed in the charging equipment that you connect to your car. The technology can quickly charge a car using mains power that would otherwise only support slower Stage 2 charging, which won’t set anyone’s hair on fire unless it’s installed in their home, a completely different scenario that battery backup isn’t for is applicable.

ADS-TEC Energy claims its technology can do a bit of alchemy.

“110 kilowatts that goes into a battery-backed charger does two things,” Tuccillo said: “It builds memory or power within the charger, so it increases the power going from charger to charger [car].” According to Tuccillo, ADS-TEC’s technology handles both tasks in a way that eliminates downtime to allow the battery backup to “catch up.”

In Brian Cooley’s video interview with John Tuccillo, hear the full vision of how battery backup could turn a congested grid into one ready for any EV we can throw at it.
