The forthcoming Kia Soul EV is to come with a class-leading battery energy density of 200 Wh/kg as a result of a three-year joint development programme between Kia Motors Corporation and SK Innovation in Korea.
Kia engineers have developed the outstanding power pack featuring 192 lithium-ion polymer battery cells in eight modules, delivering a total battery capacity of 27 kWh.
The pack incorporates state-of-the-art thermal control technology to maintain individual cells at optimum temperature and structural design to enhance crash worthiness.Nickel-rich NCM (nickel-cobalt-manganese) cathode material is used in the mass production of the battery cells for Soul EV.
Energy density, which is dependent on cathode capabilities, is a core performance factor deciding EV driving range. By exploiting the class-leading energy density of its battery, the Soul EV offers a driving range of around 200km on a single charge.
High-performance electrolyte additive and anode materials were also developed to meet various performance requirements, such as safety and lifecycle, while maintaining high energy density.
