LONDON: The Kia EV4 all-electric compact recently completed a 10,000-km Nürburgring test under near-maximum load and hypercharging conditions.
Also, its fourth-generation battery system showed a low level of degradation following a 110,000km accelerated public road simulation test.
The EV4’s endurance can mostly be attributed to Kia’s fourth-generation battery system.
The system combines advanced thermal management with optimised coolant distribution over all cell units.
These enhancements ensure that the battery operates within safe temperature levels, even under high-stress conditions.
By doing so, the system ultimately extends battery life and maintains consistent performance.
Engineers confirmed a battery State-of-Health (SoH) of 95% after 10,000km of track testing and 110,000km of road testing.
On top of its battery performance, the EV4 benefits from regenerative braking.
The system improves long-term efficiency by reducing battery strain and recapturing up to 25% of energy during deceleration.
Thanks to its robust design and intelligent energy management, the EV4 is guaranteed to retain at least 70% of its battery capacity after 160,000km driven or eight years of regular use.
