The upcoming, latest version Kia Soul EV is going to get a major update in the form of a more advanced battery. Kia has confirmed that the forthcoming Soul EV will equip a class-leading battery energy density of 200 Wh/kg, a combined effort made by Kia Motors Corporation and SK Innovation.
The battery has a total capacity of 27 kWh, thanks to the development team who managed to pack 192 lithium-ion polymer battery cells in 8 modules. For the Soul EV’s battery cells, Kia used Nickel-rich NCM (nickel-cobalt-manganese) cathode material. The main reason of using this material is of its performance factor as the actual EV driving range is decided by the cathode itself. This renders the improved Soul EV to offer a brilliant range of around 200 km on a full charge.
To take care of the safety and lifecycle of the battery without compromising on the energy density, Kia used high performance electrolyte additive and anode materials. Making the car even safer is a special secure separator which is used the battery cells which determines the charge/discharge speed and safety of the battery pack. Furthermore, it offers improved thermal resistance to maintain optimum temperature should there be an accident or exposure to heat.
Together all these technologies not only offer enhanced safety and practicality but also an outstanding charge time of 25 min via a 100 kW DC outlet or 33 min via a 50 kW DC outlet. For a full charge, the battery takes about five hours on a 6.6 kW AC source.
The car would also come with an overcharge protection device that cuts of the power to the circuit in case of battery cell swelling due to overcharging. Another interesting feature is a battery heating system which keeps the battery cell warm when it is being charged, thus maintaining optimum temperatures for easy start ups. This feature would come in extremely handy in cold weather conditions.
