SPAN Drive: What It Is and How It Works with SPAN Panel
SPAN Drive is a smart Level 2 EV charger designed to work seamlessly with the SPAN Panel. It offers intelligent, flexible charging that adapts to your home’s energy usage in real time. In this guide, we’ll break down exactly how SPAN Drive works, and why it’s a game-changer for EV owners, especially those with solar panels or limited electrical capacity.
What Is SPAN Drive?
SPAN Drive is not just another wall-mounted EV charger, it’s a smart charging solution that requires the SPAN Panel to function. The SPAN Panel gives it circuit-level control, real-time monitoring, and load management capabilities that traditional EV chargers simply don’t have.
SPAN Drive’s Built-In Safety and Features
- Lock Feature: Prevents unauthorized charging in shared driveways or rental properties.
- Circuit-Level Visibility: Monitor EV charging as part of your whole-home energy use.
- Future-Proof Design: Ready to support features like charge-sharing and V2H/V2G as they roll out.
Smart Charging Features of SPAN Drive
SPAN Drive offers multiple intelligent features that work together to deliver a seamless, efficient EV charging experience while protecting your home’s electrical system.
1. Dynamic Load Management
SPAN Drive continuously monitors your home’s total energy use through the SPAN Panel. If your household load nears your main service limit (like 200A), it automatically slows or pauses EV charging to avoid overloads or breaker trips. Once demand drops, charging resumes without you having to lift a finger. This helps you avoid costly electrical upgrades while keeping your EV charged.
2. Scheduling Charging with the SPAN App
Through the SPAN Home app, you can set preferred charging windows that fit your lifestyle and electricity rates. Whether you want to charge overnight during off-peak hours or sync charging to solar production, the app lets you automate start and stop times. Combined with load management, scheduling ensures your EV charges efficiently without disrupting other home energy needs.
3. Solar-First Charging
For homes with solar panels, SPAN Drive prioritizes using excess solar power to charge your EV. When solar production dips, it seamlessly switches to grid power to maintain uninterrupted charging. This smart solar integration maximizes your self-consumption and reduces reliance on the grid. Plus, SPAN Drive is designed to keep your charging on track even if your internet connection is lost.
4. Reliable Charging Even Without Internet
SPAN Drive continues to work even if your home loses internet access. All your scheduled preferences and limits are stored locally, so your EV keeps charging without interruption.
Why SPAN Drive Stands Out?
SPAN Drive delivers intelligent EV charging that adjusts in real-time to your home’s energy load and solar production. It eliminates the need for panel upgrades, provides app-based control, and keeps working even if your internet goes down.
If you already have—or are considering—a SPAN Panel, SPAN Drive is the smartest way to charge your EV.
