VW Backed Chinese EV Claims 620K-Mile Battery Life

A Volkswagen developed EV built in China is claiming an industry milestone of a battery pack life of up to 620,000 miles.

Chinese carmaker JAC Motors unveiled its first vehicle boasting the long-life battery pack at the Shanghai International Auto Show 2019. Its SUV-inspired iEVS4 was co-developed with Volkswagen and also boasts a comprehensive suite of human-to-vehicle interaction technology.

On top of the claimed battery life, the iEVS4 claims a normal driving range of 292 miles with a maximum cruising range of up to 372 miles. The tie-up with VW has enabled the carmaker to perfect a liquid cooling system that it says makes the battery pack less prone to overheating and extending its lifespan.

It claim for battery life is impressive compared to other manufacturers who currently off warranties of just 100,000 miles over an 8-year period. That said, a Ford engineering executive told me that its own liquid cooled battery packs for the forthcoming BEV Ford Transit LCV have clocked up more than 300,000 miles in evaluation trials with no material loss of performance, albeit over a much shorter time span.

Naturally, the present cost of replacing a vehicle’s entire battery pack still far out-strips the two major engine rebuilds or replacements in a traditional ICE vehicle. However, in practice few privately owned vehicles of any powertrain would be expected to last more than 600,000 miles, so JAC’s claims are significant in terms of projected residual values of EVs.
