Kia has introduced the 2020 Kia Soul EV, which provides a much improved range based on the same large batteries and drives as their younger Korean siblings. Again, Hyundai-Kia shows because of its ability to make convincing and affordable EV.
We know that Soul will have the same options for 64 kWh battery packs as siblings, Kia Niro EV and Hyundai Kona EV. It is likely to have much similar DC charging capabilities (CCS plug).
We still do not know what the soul’s true assortment will be (Kia has vaguely mentioned “over 200 miles”), but we can make decent estimates based on the fact that it has essentially the same drift line as its siblings. We know that the soul has slightly lower aero-efficiency than its siblings because of its distinctive boxing shape. The good news is that the 2020 version has an updated form and seems to have a slightly more smooth aero profile than the current Soul EV. The height may also have been trimmed fractionally.
Here’s a comparison of the front profiles that show more noticeable changes:
We already know that the shared drive line for these 3 Korean siblings has excellent efficiency. How much does the soul’s boxy character affect the efficiency of the highways compared to Kona and Niro?
The current generation Soul EV has a tensile coefficient of 0.35 Cd, compared to Kona 0.29 Cd. Their front surface is very similar. I estimate that the revised 2020 Soul drag coefficient will be in the range of 0.32-0.33 cd, partly due to the likely amount of less frontal area than the previous generation, because it is slightly shorter. The side mirrors also seem to have been tweaked. Where the current soul has a 21% higher overall flight profile than Kona, the 2020 soul can only be 12-15% higher. At a speed of 70 mph to 75 mph (113-120 km / h), a 12-15% flight distance will amount to approximately 6-7.5% overall energy efficiency (the drive efficiency and rolling resistance are more constant).
Summarizing all this, we can expect an EPA freeway range rating for the 2020 Soul EV which is approximately 210-213 miles (compared to Woman 226 miles) and an EPA combined range of about 240-250 miles (compared to female 258 miles). Note that EPA Combined Classification bias more against a low and moderate driving cycle, where aeroefficiency is much less of a factor. The EPA Highway Report is close to the real-time range of long journeys at steady highway speeds (70-75 mph) in decent conditions. Do not pay much attention to WLTP values, as they remain (currently at least) a political fudge between powerful automakers and weak regulators.
Our latest CleanTechnica EV driver survey shows that it has 220 miles or more of the actual range is a highly desirable option for those who want to jump aboard on the EV revolution. The soul gets the job, which probably gives about 200 miles of the real area even at highway speeds and 240 + miles at low to moderate speeds. Let’s look at how Soul’s supply and charge compare with their siblings and other affordable EV.
The figures in the chart below are a comparative guide based on actual data on driving at a constant speed of 75 km / h km / h) – something more demanding than the EPA motorway cycle, which approximates to 112 km / h: 
The blue rods indicate 90% of the total area because just As in any car, you do not expect to drive from full to empty before planning a peak. Rather, you drive from down to about 10%. The range specified from 30-minute charging (green bars) is based on optimal charging speeds from stations that can deliver full power (up to 72 kW) that the Korean power tools can benefit from. In practice, these would need to be 80 + kW or 100 + kW charging stations. However, most existing CCS charging stations in several parts of Europe and much of the US are limited to 50 kW, enabling these EV chargers to charge at about two thirds of their maximum charge power (up to ~ 48 kW in practice) . Thus, the more typical range that is added from 30 minutes of charge in most locations in 2018 is only two thirds of the optimum range specified in the graph.
The good news for electric gearboxes equipped with CCS plugs is that charging of infrastructure is rapidly improved. Switzerland, Austria, Western Germany, the Netherlands and southern Scandinavia already have a reasonable density of 100 + kW CCS chargers on the main roads, which increase and spread to wider areas month by month. There is a similar story in the US, with coastal areas beginning to see more 100 + kW chargers and other parts of the country that fill out the major highways in the next year.
Hyundai and Kia have suggested that 100 kW charge can be possible on both Niro and Soul in the future. This should be taken with a pinch of salt (it would require 275 amp charge, which is a bit of a stretch). Currently, the charts above show the optimal charging performance so far shown in the real world.
Teslas already has the strong advantage of a tight (and ever growing) charging network that guarantees convenient charging at optimal prices across Western Europe and the United States. They can also charge at or above 100 kW (120 kW for long intervals), providing a large addition range from a quick 30 minute charge. We do not yet know the real load rates for the standard and medium level variants, but the chart provides reasonable work estimates. There is also a possibility that the soon-featured Supercharger version 3.0 will further increase the charging speeds of model 3, perhaps a little north of 150 kW for the larger battery models. But again, the chart shows what we have seen so far in practice so far.
The chart shows that even on fast highways (75 km / h, 120 km / h), the Korean EVs can make a trip of nearly 300 miles 483 km) with only a 30 minute charging pause, under optimal conditions. On longer trips, it would be better to load for at least 45 minutes (Woman) or 50 minutes (Niro, Soul) to add 2 hours (150+ miles or 240+ km) scenario. It’s probably good for many families with young children and for temporary road trippers who are not in rush.
On a slower 50 kW charger, it’s 60-70 minutes of charge required to add another 2 hours of driving speed on the highways. It’s a sit-down meal break, as many people will happily fit in for a 350 mile trip (it’s 5 hours of highway driving). One hour’s meal break on a long trip, carried out a few times a year is no big deal. In an EV, this is more than weighed by saving ~ 10 minutes a week to visit a gas station. It is 8.5 hours a year saved there.
It is also worth remembering that if you have access to an overnight plug, you do not need extra effort to start a long journey from home with a “full tank” that can cover around 200 miles without any break. That’s not the case for any car. What part of the time does a gas car already have enough fuel in the tank to make a 200 mile journey without taking time for a peak?
These electric motors make it possible to force versatile vehicles for most people, and will save a ton of money over their lifetime compared to own a gas car. The soul is likely to be on its way from Q3 or Q4 2019. Like Kona and Niro, Soul will be in limited access to all markets in the foreseeable future so if you like styling and the overall package suits you, be sure to get Your booking as early as possible.
