Two EVs in a Riverview garage: one charger or two?

Build a simple weekly parking plan

Write down when each car arrives, when it leaves and which driver can move a car if needed. For a Riverview household with different work shifts, sharing one point may be practical on some days and inconvenient on others. Include where each charging inlet sits when parked. Discuss daily use first, then the occasional day both vehicles need more charging.

Use a one-week table with each vehicle’s arrival, departure, typical miles and normal parking side. Mark nights when both need meaningful charging before morning. This turns “we have two EVs” into a routine the electrician can use without pretending to predict every future trip.

Compare convenience as well as hardware

Ask for two clearly described options if you are undecided: one charging location shared by the household, and a design with two accessible charging points. Document whether either option involves moving vehicles or changing how the garage is used. A less expensive equipment list may still leave a daily coordination problem that the household does not want.

For each option, identify the equipment, charging arrangement, cable reach, electrical route, controls, permit scope and installed price. If one option depends on moving a vehicle after charging, decide who will actually do that. Keep a second-EV purchase or a future replacement vehicle visible as an assumption, not a guaranteed equipment match.

Do not assume every charger shares power

Tesla’s Group Power Management supports compatible Gen 3 Wall Connectors; its documentation distinguishes this from dynamic management for a single Wall Connector. [1] Ask the installer to identify the exact feature and product combination in a multi-vehicle proposal. Do not substitute another brand or generation after the design without checking compatibility.

Ask how the proposed system divides available power, what communications or wiring it needs, and what happens if one charger is offline. Product-specific power sharing and a building-level load-management design are not interchangeable labels. The proposal should name the equipment and included controls.

Keep capacity and future expansion explicit

The electrician should evaluate the home’s electrical configuration and the two-vehicle plan. Do not infer capacity from spare-looking breaker positions or a service label alone. Ask whether the proposal is sized only for the current two vehicles or leaves a documented path for another charger, battery or other large load.

If future flexibility changes the panel, service or control scope, price that choice separately. That allows the household to decide whether the added work solves a likely need or only an undefined possibility.

Test the agreed routine during the walkthrough

Have both drivers attend if possible. Ask what normal simultaneous charging looks like, who manages the settings and where the equipment instructions are kept. Keep the proposed operating arrangement with the project records so a later charger replacement starts from the actual design.

Park both vehicles normally, confirm cable reach and review the app or controls without changing safety settings outside the installer’s instructions. Save the model information, permit and inspection status, configuration and support contact together.
