Home Charging for PHEVs: Wallbox vs Domestic Outlet

PHEV battery packs are typically 10–25 kWh — much smaller than a BEV. This means a standard household socket (230 V / 10 A, 2.3 kW) can fully recharge most PHEVs in 5–8 hours overnight.

This is a perfectly viable long-term charging solution if:

• You charge every night and your commute is under 80 km.
• You have a dedicated, properly earthed socket in your garage or carport.
• You use the manufacturer-supplied Mode 2 in-cable control box (ICCB).

A dedicated 7.4 kW home Wallbox cuts full recharge time to 2–3 hours, giving you a full battery after a short lunch break or a few hours at home. Additional benefits:

• Safer: Rated for continuous EV charging loads — standard domestic circuits are not.
• Smart charging: Schedule charging for off-peak electricity tariffs.
• Cable management: Fixed tethered cable or locking socket — no fumbling with portable leads.
• Eco feedback: Track energy usage and CO₂ savings via companion app.

Typical installed cost of a 7.4 kW Wallbox: €500–€1,200 (hardware + installation), often subsidised by employer or local energy scheme.

Standard outlet: Fine if you charge nightly and have a dedicated, safe socket. No upfront cost.

Wallbox: Best for daily drivers wanting faster, safer, smarter charging. Pays for itself in convenience within the first year of ownership.
