You can charge the battery to full capacity in anyway you choose to, the battery does not need to be depleted to recharge. However, in order to get the most out of your TX we recommend you use every drop of energy available in the battery before recharging. For more information view our TX Driving Tips.
The battery in TX incorporates state of the art cell technology. It is designed to last the life of the vehicle, 15 years+, and the results of our rigorous testing and development programme are exceeding our expectations. The battery is covered by a 5-year warranty to provide drivers with the re-assurance they need over the initial finance period. This level of cover for a commercial EV is industry leading. Small improvements to battery technology will be out-paced by the growing availability of rapid charging infrastructure, so for the mid-term we don’t anticipate developing any significant improvements to the electric range. As with all developing technologies, prices drop over time. For that reason we can't speculate on what the cost of replacing the battery in TX would be in 5, 10 or even 15 years’ time.
The TX battery is protected against extreme heat by a tough metal casing. In an event of an accident, the automatic safety systems will completely disable all high voltage hazards in under a second of an impact being detected, preventing any electrical fault from creating a risk of fire.
The high voltage control system monitors the electrical circuits hundreds of times every second to check all of the high voltage components, the electrical connectivity and the connector sealing, are all within safe-working parameters. If any possible fault is detected, such as unintended tampering, the system is shut down to prevent injury.
The drive battery fitted to TX has been developed in conjunction with LG Chem, the world’s largest automotive battery manufacturer. The gross capacity of the battery is 31kWh and around three-quarters of this is what’s known as ‘usable energy’. This means that a full charge, from 100% down to 0% on the battery charge indicator, represents 23 kWh of energy.

As well as its inaccessible location beneath the vehicle, the battery pack weighs almost 350kg. There are 35 different fixings, as well as the exhaust, high voltage wiring and cooling system, that would need to be disconnected before removal. Without specialised equipment and a vehicle lift, removal of the battery is virtually impossible.
Electro-magnetic radiation is all around us, generated by electricity cables, radio and television signals, microwave ovens and mobile phones to name just a few. Like any product, all new vehicles have to meet strict regulations around radiation levels in order to be sold in Europe. The Vehicle Certification Agency (VCA) oversee these tests in the UK and our cab passed these with flying colours.
Because our drivers spend much of their working day in close proximity to the battery, LEVC considered it necessary to gain additional specialist accreditation. The International Commission on Non-Ionizing Radiation Protection (ICNIRP) have developed stringent guidelines designed to protect against any adverse health effects as a result of frequent long-term exposure to electric and magnetic fields.
LEVC are committed to building a taxi that meets the highest sustainability standards. All procurement contracts make clear our commitment to ethical procurement and the protection of human rights. Our supplier, LG Chem has a responsible mineral sourcing policy, and have a clear process in place for auditing their supply chain. They are also a member of the OECD’s Responsible Cobalt Initiative which seeks to take collective action to address the social and environmental risks of cobalt sourcing.
We have worked to deliver an extremely robust battery which is intended to last the full 15 year lifespan of the vehicle. In addition, we are working with potential partners on a longer term sustainability solution and are hoping to make an announcement in due course.
Just like a conventional vehicle, TX relies on a small 12 V battery to run the ancillary systems when the vehicle is switched off, as well as to 'start' the vehicle (in this case to activate the high voltage systems). On-board systems monitor the level of charge in this battery to protect it from going flat, but it is still possible to drain the charge. This may be caused by, for example, improper fitment of third party equipment or a taxi that is left unused for extended periods. Again however, just like a conventional vehicle, the TX can be connected to a battery charger or jump started using the remote terminals under the bonnet. If the vehicle is completely flat and the remote door locking is inoperable, a manual key is housed within the key fob and can be used in a hidden door lock to open the doors. Once restarted (or connected to a charge point) the charge in the high voltage battery is used to replenish the 12 V battery.
Our battery has been chosen because it is an appropriate size to cover most taxi driver’s daily usage. Bigger batteries are required in high-performance passenger vehicles to ensure adequate real-world range is maintained when the power available is utilised. However in a commercial vehicle, bigger batteries mean more cost and more weight, reducing the efficiency and running cost advantages of the electric taxi. TX is backed up by a petrol range-extender to reduce range-anxiety and provide greater usability and flexibility.
Recyclability plays an important part in LEVC’s product development strategy, with more than 95% of the materials in TX classified as recyclable or recoverable at the end of the vehicle’s life.
While the usable capacity of all batteries reduces over time, the drive battery developed for TX has been designed to last the life of the vehicle, retaining its performance and range reliably for many years.
Wider industry analysis* shows that batteries removed at the end of a hybrid or electric vehicle’s life typically retain around 80% of their original storage capacity - and this is in line with our own testing. While these batteries are not suitable for immediate re-use in the same application, it is possible to refurbish and recondition the battery. However, these used batteries are also ideally suited to ‘second life’ applications, where the remaining useful storage capacity is unrelated to original automotive requirement. One example of this is the growing market for domestic and commercial energy storage and LEVC is exploring ways to reuse TX drive batteries in this way.
Regardless of the methods ultimately used, motor manufacturers remain responsible for the safe collection, recycling and disposal of all the drive battery components as part of ELV (End of Life) legislation. LEVC is committed to minimising TX’s environmental impact throughout the vehicle’s working life and into retirement.
