❓Frequently Asked Questions: EV Charging & Wallbox in Dorchester

Local insights on yields, utility rates, and incentives across Dorchester:

Why is a 48A or 40A Level 2 wallbox preferred over a standard 120V outlet in Dorchester?▼
A dedicated 240V Level 2 charger provides 25 to 40 miles of range per hour of charging, fully recharging an EV overnight, compared to just 3 to 5 miles per hour from a standard 120V outlet.
Is routine charging from a standard 120V household outlet safe in Dorchester?▼
Only for intermittent, light charging. Sustained 12-to-16-amp continuous draw over 12+ hours can overheat aging branch circuits, creating a serious thermal fire hazard and up to 20% charging losses.
What are the benefits of bidirectional charging (V2H / V2L) in Dorchester?▼
Vehicle-to-Home (V2H) allows your EV's massive 60 to 100 kWh battery pack to power your entire house for several days during emergency grid blackouts or peak TOU pricing windows.
What is solar surplus EV charging and how does it work in Dorchester?▼
Smart EV chargers monitor home electrical generation in real time, directing only surplus rooftop solar power into the EV battery rather than exporting it to the utility grid.
Why is daily charging recommended up to 80% State of Charge (SoC)?▼
Restricting daily charging between 20% and 80% SoC prevents lithium plating and thermal stress, substantially extending EV traction battery lifespan.
What does it cost to drive 100 miles using solar vs. grid power in Dorchester?▼
At 3.0 miles per kWh, driving 100 miles on utility electricity in Dorchester costs roughly $4.50 to $7.00. Fueling with rooftop solar drives that cost down to under $1.80 per 100 miles.
