How it Works

Fleet EV Charging Made Effortless

From deploying battery units to managing energy, charging vehicles, and swapping batteries, we take care of it all so your fleet never slows down.

Full Service Charging

We tow the Mobile Battery Charger to your site and drive around plugging in vehicles. When the battery is depleted, SparkCharge recharges or swaps it so you never run out of energy. We deliver, plug-in, recharge, and manage everything—no effort from your team.

Self-Service Charging

SparkCharge drops off the Mobile Battery Charger at your site. Your team plugs in vehicles as needed. We monitor energy usage remotely and swap the unit with a fresh one before it runs out. We deliver the power, you plug in vehicles yourself—we handle recharging.

Hybrid Grid Assisted Charging

The Mobile Battery Charger is placed in one spot and connected to any available grid power (no large-scale electrical upgrade required). Vehicles charge from the on-board battery; the grid connection trickle-charges that battery in the background. Connect to your existing power for continuous on-site charging.
