Charging the I-Pace
Here's a quick primer on charging the I-Pace, anno 2020
Nominal battery capacity is 90kWh, but there's a bottom and a top buffer of actual use, and a top and bottom buffer for displaying 0% to 100%. For purposes of discussion, I'm going to round things off and assert that there are 80kWh in the battery in the range of 0% to 100%.
I-Pace uses the CCS standard, which is not compatible with Chademo or Tesla Superchargers. CCS has a subtype, J-1772, which is a reduced plug for Trickle- or Level 2-charging. Thus, the I-Pace fast-charges via a CCS plug and Level2-charges via a J-1772 plug on the charger.
Mode of charging
2. Charger specs
3. Time it takes from X to Y% SoC
1. Jaguar-supplied cable that comes with the car in the US
2. 110V, standard home outlet.
3. Charges at about 1kW, so going from 0% to 100%, or 80kWh, will take 80 hours.
Level 2 charging
1. ChargePoint and a host of other suppliers for home, as well as Tesla Destination Chargers and Level 2 chargers installed at hotels and such
2. Typical specs are 240V / 32Amp outlet (e.g., via a NEMA 14-50 plug at home on a 50 Amp circuit), i.e., 7.2kW charging
3. Because this is AC charging that goes via a DC converter there is about 10% loss. So, assuming 6ish kW going into the battery, we're looking at 13 hours to go from 0% to 100%
DC Fast Charging (DCFC)
1. ChargePoint, Electrify America (EA), EVgo, and other fast charging suppliers. Akin to gas stations.
2. The most common type is currently 50kW. Faster chargers such as the more recent EA have greater nominal power; but the I-Pace throttles charging as the battery fills up, and so the average charging rate is in a fairly narrow band around 50kW.
3.a. A 50kW charger will charge at 50kW to 80%, then throttles. Thus, 0% to 80% takes about 1:15 hours. Another 20 min to get to 90%. Getting to 100% is a waste of time.
3.b. A 150kW charger will start charging at about 80kW but be quickly throttled down. Thus, 0%-80% will take about 1 hour. Then same as for 3.a. above
