Only one 7.2KW Onboard Charger for Home charging?

Hello All,

I made a deposit and ordered my I-Pace yesterday.

The onboard charger in the I-Pace apparently only charges at 7KW/hr, so if the I-Pace is "empty" it will take 12 hours to charge on a 240volt home charger!

"For optimum charging at home, you can purchase and install a Jaguar approved home charger. The I‑PACE is equipped with a 7 kW single-phase AC on-board charger, which can fully recharge the vehicle overnight"

In most cases we won't be "empty" but if I get home late from work and my wife needs to leave early (we are both pilots with weird schedules at times) it may be an issue as we both have about 140 mile round trip commutes with charging possible at work but not always available.

This lack of charge rate is very surprising considering the original "classic" Teslas had 9.6KW dual chargers (total output of 19.2KW) and current Teslas with the 100KW batteries charge at up to 17.3KW/hr but require a 90AMP AC breaker on the home panel.

The 7KW onboard charger takes advantage of almost the entire capacity of most home level 2 chargers which require a 40 amp breaker.

Hopefully they will come out with a dual charger option in the future. The reason I'm interested in this is that I have a level 2 home charger now that outputs up to 30AMPS.

I'm meeting with my electrician tomorrow to sign-off on the electric for a new home we are building. We used the Tesla as an example of the power we would need to "future-proof" it. We put a two hundred amp sub-panel in our garage and are running wiring that is capable of 100 amps to each sidewall.

It looks like we won't need it for the I-Pace as the 30AMP "charger" can supply sufficient power for the I-Pace charger which draws about 30amps AC to output 7KWs.

Does anyone have any info on possible dual chargers onboard the I-Pace in the future?

Otherwise, I just love the I-Pace and am looking forward to seeing one in the flesh!

Bottom line is that 2 people with 140 miles commutes at different times of the day and having just 1 car is an extremely unusual use case. For the overwhelming majority of people, overnight charging is fine. Charging circuitry is very expensive and heavy. Building a large onboard charger for the tiny number of people that need it would be a very questionable design decision

Btw, the term kW/hr is meaningless. kW is already a unit of charge rate.

You could always install your own DC Fast charger in your garage. In that case, you could charge up at a rate up to 100kW and completely fill the battery in an hour or so. And then all the heavy charging electronics would live in your garage not inside your car.
