We keep the process straightforward so you know exactly what to expect at each step.
We visit your property to evaluate your electrical panel, identify the best charger location, and confirm what circuit work is needed. No guesswork, no surprise scope changes later.
We outline the exact work required and pull any permits needed by your local jurisdiction. Fremont and surrounding Bay Area cities have specific requirements, and we handle all of that.
Our electricians run a dedicated 240V circuit, install the charger, and verify all connections meet code. Work areas are left clean when we're done.
We test the charger with your vehicle before we leave and walk you through how everything works. Inspection sign-off is coordinated when required.
Q1
Most homeowners benefit from a Level 2 (240V) charger, which charges significantly faster than a standard 120V outlet. The right amperage depends on your vehicle and how much daily range you typically need. We can help you choose during the site visit.
Q2
Not always. We assess your panel's available capacity before recommending anything. If there's enough headroom, we add a dedicated circuit. If the panel is already maxed out, we'll let you know what a panel upgrade would involve before you commit.
Q3
Yes, a permit is typically required for a new 240V circuit installation in Fremont and most Bay Area cities. High Voltage Electric handles permit applications as part of the installation process.
Q4
Most residential EV charger installations are completed in a single day. More complex jobs, like running conduit across a longer distance or coordinating a panel upgrade at the same time, may take longer. We give you a clear timeline before starting.
Q5
Yes. We install chargers in attached garages, detached garages, carports, and outdoor locations. Outdoor installations use weatherproof equipment rated for exterior use.
Q6
We install most major brands including Tesla Wall Connector, ChargePoint, Emporia, Grizzl-E, and others. If you already purchased a charger, we can install it. If you need a recommendation, we can help with that too.
Q7
Yes. We regularly work in Hayward, Oakland, San Leandro, Union City, Castro Valley, San Lorenzo, and Emeryville in addition to Fremont.
Q8
