2025 Corsair PHEV 120 volt charging vs 240 volt charging

[1carguy]

Hi all,

I am charging in the garage with 120 volt, but wondering about the cost's of 120 volt charging vs 240 volt charging. It takes 12 hours (+ or-) to do a 120 volt charge, and supposably 3 - 4 hours to do a 240 volt charge.

BUT, which charging method will cost the most?

Your thoughts please - thanks

It won't make any difference. Your car will charge to the same number of KWH - it just takes less time at the higher voltage. Roughly 1/4 the time for 2x voltage.

120V will cost maybe 10% more because 120V is typically less efficient than 240V.

240v will be more efficient and cost less to charge.

I've been plugging in since 2011 and have learned a few things about current battery tech/chemistry and daily use.

Heat is the enemy of long term battery health. Using L2 (240v) on a hot summer day, in the afternoon, in the sun, at a heat soaked parking lot with a depleted hot battery is the worst case scenario. Charging a hot battery, then letting it sit for hours at 100% is also not good for health. So, faster charging can "cost" more in the long run. Higher charge rates are also harder (heat) on the power electronics (inverter).

Except for extra opportunity charging during daily activities or limited charge time windows (greedy electric company day rates), there's little benefit to L2 charging on such a small phev battery.

I'm not trying to introduce any FUD to the conversation, L2 is fine but L1 (120v) is better for most folks. Also, L2 costs (installation, charger) will never be recouped through efficiency gains. If you see driving EV is the future (and it is), I recommend purchasing a larger L2 unit than needed for a PHEV for future, larger battery BEV's you'll eventually consider purchasing.
