Grayson eyeing £25m electric vehicle opportunity with thermal management system

A vehicle thermal management system (VTMS) that saves weight and optimizes range in electric buses, utility vehicles and off-road applications marks its first year of production.

Grayson Thermal Systems’ VTMS combines battery thermal management and heat pump and air conditioning technology into a single system that helps the end user save cost and space.

The technology, which also incorporates waste heat recycling and electric motor cooling to provide the complete solution, is set to tap into demand for cleaner transport and bosses believe sales of double-decker electric buses could generate 15 million in sales by the end of 2023. and over £25m by 2025.

To take advantage of trade volumes also starting to grow from 2024, Grayson is investing heavily in its UK manufacturing and construction capacity, which will create dozens of jobs locally.

“The beauty of our VTMS is that it brings together all of our proven battery thermal management and heat pump technologies for zero-emission vehicles into one neatly packaged system,” said Matthew Hateley, European Sales Director at Grayson Thermal. Systems.

“Our unique software platform and intelligent control logic allow components to be shared for different uses, which means a smaller and lighter solution, while our engineering team has also developed a unique way to recycle the energy wasted in the system – helping the battery save energy while, while delivering optimal heating and cooling performance.

He added, “The commercial vehicle platform has been designed in a modular fashion so that the OEM can incorporate the technical features they want based on system performance requirements, cost and weight goals.”

Wrightbus, a leader in hydrogen and electricity technology for the transport sector, became the first company to integrate the Grayson vehicle thermal management system into parts of its fleet last year, a move which helped the StreetDeck Electroliner officially become the world’s battery-electric double-deck bus.

Official evaluations conducted at UTAC – using the ZEMO-accredited ULEB (Ultra Low Emission Bus) test – showed that the bus achieved a result of 0.68 kWh/km.

This is around half the energy consumed by its closest UK bi-level rival BEV and a major contributing factor to this impressive result has been the low power consumption of the Grayson VTMS to meet HVAC requirements and maintain battery temperatures during the test.

Hateley said: “We set a high expectation for what we wanted to achieve in terms of weight savings and fuel efficiency, so to accomplish the test results we have gives us a high level of confidence that our technology will change HVAC requirements for electric vehicles. still.

“More than two years after setting our strategic goals, it’s fantastic to see our vehicle thermal management system on the roads in and around the UK.”

Ian Gillott, Managing Director of Wrightbus, said: “We are delighted to have integrated the Grayson vehicle thermal management system into part of our fleet. Thanks to this, our StreetDeck Electroliner has become the most efficient double-decker battery-electric bus in the world, something of which we are extremely proud.

“Thermal management is critical to vehicle efficiency and the partnership between Grayson and Wrightbus has allowed us to fully optimize it. As a leader in the zero-emissions transportation industry, we are delighted that Grayson is doing everything in its power to further improve the performance and green credentials of our vehicles.

Hateley added: “We are now entering the next stage of development to further improve our product to optimize the performance and green credentials of electric vehicles while complying with new legislation which will come into force in 2024.

“VTMS is the latest system we’ve introduced to our product line, and we’re delighted to have played a small but important role in naming the StreetDeck Electroliner as the world’s most efficient dual-deck battery electric bus. .

“Both companies share a passion for innovation and this will only continue as we aim to provide greener transport solutions for the sector.”
