There is a research paper on the AVT site that shows graphs for charging four different Soul EVs at 0°C, 25°C and 50°C
PDF report here - DC Fast Charging at Different Temperatures
The cars are tested inside a container with controlled temperatures.
Four different Soul EVs using Chademo at 50°C
I am particularly interested in Note 5 at the bottom.
The thermal regulation load is an approximate calculation of the amount of energy used by the vehicle to regulate ESS temperature, where applicable. This is calculated by subtracting the amount of energy into the ESS from the amount of energy output by the DCFC; the calculated value also includes resistive and conversion electrical losses.
In the case of the Kia Soul EV, thermal regulation was engaged during the 50ºC test. However, it is possible that the energy values noted for the 0ºC and 25ºC tests are due to parasitic losses or powering of the vehicle fast charging system. There are three possibilities for how the onboard vehicle electronics receive power during a fast charge
1) 12 V interface on the CHAdeMO c harger,
2) DC-to-DC converter steps high voltage down to 12 V,
3) the system could be powered directly from the 12 V battery of the vehicle.
It might be interesting to compare the energy required to cool the pack at 50ºC from various different EVs. !!
Especially when I see this in the report for the BMW i 3
"During testing, fast charging at 50 °C DC was not able to be conducted due to the vehicle preventing the charge event from occurring."
Annoyingly for the 2013 L eaf
"The enclosure temperatures were not measured during the initial testing of the 2013 Nissan L eaf, but they will be recorded in future testing."
