Install 240v charger in the garage?

Hi,

I have a 2018 Kia Niro PHEV EX.

Wondering what is the best approach to install a 240v charger in the garage for plug in? Just call an electrician and install a 240v socket? Or is it more than that? Googling showed up a CharePoint electric home charger which is super expensive.

Please advise.

Thanks,

Yeah, the ChargePoints are nice but very pricey. Fortunately, since the Niro can't take advantage of the higher charging current it provides you can just use one of these:

You can have an electrician install a 240V outlet in the garage and you are good to go. I plan to pick one up soon myself. I've been very happy with the 120V charger, but could use the faster charging on the weekend when we take several short trips.

Depending on how handy you are, and where your panel is in your house, you can run your own wire and plug then get it inspected by your electrical athority. A 20amp line isn't all that hard and the only difference between 120 and 240v is that you have a black and red wire, rather than a black and white. The two legs on the 240v are hot, where 120v you have a hot and an neutral.

I'll add: a 20a circuit requires 12g wire, not 14g which is used for 15a circuits.

Just a bit of advice from a former PHEV owner (2013 Cmax Energi) - recharging several times a day for short trips will hasten the degradation of your battery. Charging heats it up, so does discharging it driving on the road. If you start charging while it's still hot from driving (like right after you come home), then it will get even hotter. It's load of fun to drive all EV, but this isn't a LEAF or Tesla, and is not a liquid cooled HEV. Makes no difference now, but in a few years you'll notice you won't be getting 26 EV miles on a charge as the LiOn loses battery capacity. Read the fine print in your owners manual - don't charge while hot, and battery capacity loss over time is normal. My Energi dropped in 5 years from 26 miles EV to 15 miles EV, as driving capacity dropped from 5.2 kWh to 3.6. Mind you, it will always be able to run as a hybrid, but we did buy the PHEV battery. Like Ford, I don't expect Kia will establish a minimum PHEV capacity as a warranty replacement.

any guidance on how long to let it cool down before charging?

Move to Canada. From now until April, we don't seem to have any problem with getting cars cold, in a pretty quick manner. Sadly it's a bit of a bitch with the fuel economy though.

I've programmed the car to charge off peak midnight to 7am. Since I'm usually home by 10 p.m. that gives the car battery 2 hours to cool down in a rather cooler nighttime garage even in the summer.

While it is true heat is not advantageous to either battery charging or discharging it is unlikely that KIA engineers didn't take this into account. Temperature sensing will protect the battery and the car with heavy discharge and possible battery temperature gain on a steep uphill climb and immediately will still rapidly charge the battery on the downhill. The garage charge cycle even if immediately done after use of the car is minor to the probably already solved uphill downhill cycles and battery temperature issues. The only component that is exclusive to garage charging is the in car converter. The on the garage wall current provider ( aka charger) communicates using PWM ( Pulse Width Modulation) via a pilot wire to the in car converter ( AC to DC). The car will discontinue charging and communicate this the the garage wall unit via a voltage drop on the pilot wire if conditions require it. The car will re-communicate when it needs continued charging.The pause is rare and is a result of temperature or even rarer pressure build up in the battery. The most common pilot signal is the full charge signal.
