Somerville, Mass.-based SparkCharge likes to describe itself as sort of a Doordash or Ubereats for EV charging. Through its Currently mobile app, an EV owner can order a recharge and a SparkCharge van is dispatched to the driver’s location, “the same way me and you get food and pizza delivered,” SparkCharge CEO Josh Aviv told Forbes.com.

Its portable Roadie hardware is basically a stack of batteries that can be wheeled right up the the vehicle. It’s especially useful for fleets, rental car companies or insurance roadside services. A stack of four Roadies can provide about 60-70 miles of range in an hour.

Aviv said many of the communities SparkCharge services are under served by what he termed “traditional charging companies,” so his company is making up the difference.
