Making our new taxi zero-emissions capable was essential to meet the changing demands of the market and wider environmental concerns. As with any technological change, it’s normal to have concerns over the reliability and longevity of an electric drivetrain and in particular the drive battery. Although many concerns are based in some truth, rumours are often exaggerated.
From the outset, it was a key design objective to ensure the drive battery would last the life of the taxi, and that required the right expertise. The cutting-edge lithium-ion battery ﬁtted to TX has been developed in conjunction with LG Chem, the world’s largest automotive battery manufacturer.
Although the storage capacity of all batteries will gradually decrease over time (known as ‘ageing’), this eﬀect can be minimised. On-board systems constantly monitor and manage energy usage to protect the battery, such as a cooling system dedicated to keeping the battery at exactly the right temperature whether operating in extreme ambient temperatures, under heavy usage or during rapid charging. In fact, extensive testing has shown that even under the most demanding operating conditions, our drive batteries retain at least 75% of their original charge capacity after 9,000 use cycles – that’s the equivalent of more than half a million miles.
For even greater peace of mind, the drive battery is covered by a comprehensive ﬁve-year, unlimited mileage warranty – the duration covered by our longest Personal Contract Purchase agreement, at the end of which you can choose to buy the taxi outright or return it to us.
