Kia Motors has unveiled its first ever mass-production electric vehicle, the Soul EV at the Chicago Auto Show.
Set to go on sale in the United States market in third quarter of 2014 and in Europe and the UK after that, the Soul EV will be Kia’s first all-electric, zero-emissions car sold in the U.S. and expands the brand’s line of environmentally conscious vehicles.
Kia’s eco-friendly commitment was further underscored when UL (Underwriters Laboratories) 2 honoured the Soul EV with the organization’s first automotive environmental validation for its integration of more than 20 bio-friendly materials.
A top concern for EV buyers has commonly been range anxiety. The Soul EV addresses this issue by utilizing a highly energy-dense lithium-ion polymer battery. Located beneath the floor, the 27kWh, air-cooled, 200 watt-hour/kg battery is expected to yield a range of approximately 80-100 miles of real-world driving on a full charge, with internal testing and evaluation results exceeding 100 miles in some instances.
The 360 volt 96-cell lithium-ion polymer battery has been engineered for high capacity, thermal stability and safety. Accordingly, the battery features a nickel-cobalt-manganese cathode, which helps increase capacity, and a graphite-based anode, which increases durability while reducing weight. Additionally, the cells use a gel electrolyte, and each cell contains ceramic separators to significantly improve thermal stability and safety.
In an effort to maximize efficiency and range, the Soul EV uses Kia’s third-generation regenerative braking system to capture up to 12 percent of the car’s kinetic energy, which is fed back into the battery while the Soul EV is coasting and braking. Soul EV owners can choose between four different regeneration modes: “Drive” or “Brakes” modes in Eco-mode “Off,” and “Drive” or “Brakes” modes in Eco-mode “On” (the “Brakes” setting with Eco-mode “On” producing the most regeneration).
The Soul EV makes charging easy by plugging into any standard 120v outlet or a conventional 240v EV charger. Two charging ports are standard, including a SAE J1772 port for Level 1 and Level 2 AC, and a CHAdeMo DC fast-charging port (480v). Found behind a sliding door located in the front grille, the dual ports offer flexibility and increase the Soul EV’s go-anywhere appeal, making it more convenient to charge inside the owner’s garage or when on the road. Recharging times vary from 24 hours for a fully depleted battery using a standard 120-volt outlet and under five hours when plugged into a 240-volt outlet. An 80-percent charge can be achieved in as little as 33 minutes with a 50 kW-output charger.
The front-wheel drive Soul EV is powered by an 81.4 kW, 109-hp electric motor, producing a generous 210 lb.-ft. of torque. The liquid-cooled AC synchronous permanent magnet motor uses multi-layer magnets to help improve efficiency and reduce the whine that’s commonly experienced with other electric vehicles.
The motor delivers its power to the front wheels through a single-speed constant-ratio gear reduction unit. Acceleration from 0-60 mph is expected to take fewer than 12 seconds with a top speed electronically limited to approximately 90 mph. The battery’s location beneath the floor offers the stable feel of a lower centre of gravity, which helps ride and handling and ensures that the EV remains true to the Soul’s fun-to-drive reputation. Additional cross bracing beneath the low-mounted battery contributes to a 5.9 percent improvement in torsional rigidity over the petrol or diesel-powered Souls.
