While the model is yet to be confirmed for sale in Australia, overseas customers will have more than twice the warranty coverage on the battery pack than for the rest of the car.
The Lexus UX 300e uses air-cooled technology to keep its 54.3kWh lithium ion battery pack operating within a safe temperature range.
Lexus says the technology is “safer and lighter than water-cooled systems”.
“With cooled air circulating inside the battery pack, stable battery output can be attained even at high speed and during repeated rapid charging,” Lexus said.
“Working hand in hand with the cabin air conditioning, the system enhances the car’s performance, battery life and charging performance.”
By comparison, US electric car specialist Tesla opts for liquid cooling technology for its batteries – offering a 240,000km warranty on battery packs used in its Australian Model S and Model X cars and between 160,000-192,000km for variants of its Model 3.
The Lexus UX 300e is on sale now in China, with plans to introduce the model into some European countries by the end of the year.
Lexus says the UX 300e has a claimed power output of 150kW and more than 300km of driving range on the newer, stricter WLTP testing cycle.
Will the Lexus UX 300e come to Australia?
While Lexus Australia has expressed interest in bringing the UX 300e here, the model's local future remains unclear.
Lexus Australia has told CarAdvice there are no local changes regarding the UX range since the most recent updates arrived in 2019.
"The UX300e is initially intended for sale [in 2020] in China and Europe and Japan the following year. No plans have been announced for other markets," Lexus Australia’s chief executive said at the time.
"Should it become available, we would love to be able to offer this vehicle in Australia once issues such as charging infrastructure are resolved."
