The first all-electric Lexus features a monitoring system that monitors the voltage of each battery cell, as well as a particularly safe and lightweight air cooling system for the highest possible efficiency and range. Lexus offers an extended ten-year warranty on the high-voltage battery.
The battery life and performance of e-vehicles are affected by intense heat. That's why Lexus engineers have developed an air cooling system for the battery cells of the Lexus UX 300e all-electric premium crossover (combined power consumption 17.1 - 16.8 kWh/100 km). It is safer and lighter than water-cooled systems and at the same time enables air conditioning of the interior. This makes it possible to ensure efficient cooling and thus stable battery performance even during sustained high power output such as at high speeds and repeated rapid charging.
The cooled air circulates inside the sealed battery pack, which has special rubber seals to protect it from water, dust and external influences. The cooling system enhances the Lexus UX 300e's performance, battery life and charging speed, while also improving interior comfort, according to Lexus.
Cold temperatures also affect battery performance, which is why Lexus added a heating element to each battery module in the UX 300e. This minimizes the climatic impact on range, and full battery power is available from the start. Even in extreme temperatures around -30 °C, maximum battery power is achieved and charging time is reduced from 25 hours without a heating system to just 8 hours and 15 minutes.
Lexus is confident in the performance and durability of the batteries and offers an extended ten-year warranty (or one million kilometers) on the high-voltage battery, covering all malfunctions and a drop in capacity below 70 percent. This is subject to regular inspections at an authorized Lexus dealer as specified in the maintenance program.
The lithium-ion battery in the Lexus UX 300e is designed to last the life of the vehicle. With a take-back system, Lexus also guarantees safe and responsible recycling at the end of its service life. The premium brand currently already recovers more than 90 percent of its batteries used in Europe. A 100 percent take-back rate is being targeted.
