STC member HV Wooding collaborates with Nuclear AMRC to target £1m electrification boost

Silverstone Technology Cluster

29th November 2022

Development of a new powder coating process for parts destined for electric vehicles is set to deliver a £1m boost for Silverstone Technology Cluster member HV Wooding.

The Kent-based business, which specialises in providing precision engineered metal components for the automotive and aerospace sectors, is working with materials and engineering researchers from the Nuclear Advanced Manufacturing Research Centre (Nuclear AMRC) and the University of Sheffield to improve the quality of the busbars that it produces.

Supported by Innovate UK through the Faraday Battery Challenge, the project focuses on investigating and developing alternative coating methods that will improve the performance and integrity of the critical components. These carry high-current power between different parts of an electrical system.

“Current coating methods are difficult to control, with up to a high level of components rejected because of poor quality insulation,” explained Paul Allen, Sales Director at HV Wooding, which works with a number of businesses across the STC region working on EV programmes.

“There is currently no standard specification or process available; our new method will contribute supply chain capability and capacity for battery and energy storage applications.”

He continued: “We will develop a best practice testing method to standardise quality assurance where there is currently no international standard and this could generate up to £1m in additional sales to our business.”

HV Wooding previously worked with the Nuclear AMRC through the Fit For Nuclear programme, which helps manufacturers meet the quality expectations of the nuclear supply chain.

The company will look to maximise the Centre’s advanced manufacturing methods, as well as tapping into University researchers, to develop a standardised test procedure for quality assurance, demonstrating that each busbar meets all the required integrity standards with minimal risk of failure in use.

“The current busbar coating process is difficult to control and can’t currently be scaled up to meet customer demands in the UK,” commented Dr Li Li, head of the Nuclear AMRC’s control & instrumentation research group.

“This funding enables collaboration between a UK SME business and academia to tackle a real pressing issue, and this project will help ramp up production at HV Wooding whilst also minimising the product failure rate.”

Paul added: “Powder coated insulated busbars are safer than heat shrink sleeved alternatives. They have better thermal and electrical performance alongside other benefits in compact battery design –for example saving up to 10% clearance and creepage distance.

“If the innovative and optimised epoxy powder coating process is implemented then it will definitely open up new markets and will lead to new skilled jobs in our area.

“The successful project will support the overall goal of the Faraday Battery Challenge and scale-up British busbar manufacturing for battery modules and packs in accordance with the UK’s Ten Point Plan for a green industrial revolution.”
