VoltEdge Tools
Free, browser-based calculators and decision helpers for EV ownership, home charging, electrical planning, incentives, solar, batteries, and project questions.
Start With the Decision in Front of You
Electrification gets confusing when every question is treated like a separate purchase. A better sequence starts with the operating math, then moves toward equipment and project scope. Use the Charging Cost Calculator to understand what driving and electricity rates do to your monthly cost. When home charging is the next decision, compare charger needs and use the panel estimator to prepare for a documented load calculation and a qualified electrician conversation. If incentives could change the timing, check them before treating any rebate or tax rule as guaranteed.
Solar and storage come after the load is clear. The six energy calculators expose the formulas for appliance use, battery runtime, array production, solar-powered EV miles, time-of-use shifting, and demand charges. The Electrification Blueprint connects those questions into one planning path; its optional Scenario Passport stays in your browser unless you choose to export it. The Quote Decoder helps you see what a proposal documents without declaring a contractor or price “good.” For ownership and buying questions, the battery warranty timeline separates published coverage from predictions, while Smart Search can find the right guide or hand a real question to Ask VoltEdge. These tools are educational starting points—not installation, safety, tax, legal, warranty, or financial verdicts.
