The Jaguar I-Pace won’t ever need its battery replaced… theoretically

One of the real highlights at this year’s Los Angeles Auto Show is the all-new, all-electric Jaguar I-Pace Concept.

Apart from its cutting-edge styling and advanced technology, Jaguar is billing its first ever electric vehicle as a full-blown performance SUV.

The luxury British carmaker claims combined power and torque from its state-of-the-art electric motors (front and rear axles) and 90kWh lithium-ion battery pack is 294kW and 700Nm – the same torque rating as the high-performance F-Type SVR.

Performance is said to be scintillating, with the I-Pace capable of going from a standstill to 100km/h in around 4.1 seconds, with a range more than 500km.

Charging is also relatively quick, at least when using a 50kW DC plug and facility. Zero-to-full charge capability will take just over two hours, while an 80 per cent charge is reached in 90 minutes.

Importantly, and unlike most other electric vehicles, and you won’t ever need to replace the I-Pace’s battery pack. At least, that’s the view of Dr Wolfgang Ziebart, Technical Design Director Product Development at Jaguar.

“We expect the battery will last the entire lifetime of the car. If you look at the specification of the cells – 1000 cycles of full-span zero-to-100 per cent – that’s what the battery pack can do.

“In our case, as we have a range of 500km, 1000 cycles would mean the battery has a life of 500,000km, which should exceed the life of the vehicle.

“But what we must also consider is that people don’t bother with maximum range charging, rather it’s more like 90 per cent. And on the other end of the scale, the driver is more likely to run the vehicle down to 20 per cent of remaining charge, rather than a complete depletion of battery power”, Ziebart added.

“So the battery doesn’t actually cycle between 0 and 100, rather, it’s more like between 20 and 90, which adds quite a lot to the battery life.”

Ziebart believes it’s even better than that, given the fact that standard 1000 cycles are based on a fast-charge using a high-powered 100kW charge in one hour continuously.

“Of course, that’s not the norm when it comes to electric charging behaviour. They will only use the high-power system occasionally when they need to drive a longer distance.

“The standard charging practice is to plug-in at home and charge overnight for around 10 hours, which puts a lot less stress on the battery”, he added.
