Why the Inability to Repair EV Batteries Could Drive Insurance Premiums Up

As electric vehicles (EVs) become increasingly common on the roads, a worrying trend is emerging that could significantly impact insurance costs for EV owners. According to insights from Thatcham Research, an organization backed by major motor insurers, insurance premiums for electric vehicles are likely to rise unless the UK finds a more economical method to repair damaged batteries instead of replacing them.

The High Cost of Damaged Batteries

At present, the cost of repairing an EV battery is prohibitive. This component can account for up to 55% of a new EV's value and represents an even larger portion as the vehicle ages and depreciates. Consequently, many electric vehicles with battery damage are being deemed a total loss, leading to write-offs that increase costs for insurance companies and ultimately for consumers.

The correlation between battery damage and rising insurance costs is profound. Although the number of EV repairs has increased, only about 2% of total EV repairs involve battery work. As the number of electric vehicles on UK roads exceeds 1.5 million, establishing a robust battery repair and refurbishment industry becomes critical to mitigate surging claim costs.

Industry Response: Need for Repair Solutions

Dan Harrowell, a principal engineer for advanced technologies at Thatcham Research, emphasizes the importance of focusing not just on battery recycling but on the repair and refurbishment processes. He draws a comparison between the current practices in the electric vehicle sector and those established in the internal combustion engine (ICE) sector, where independent repairers routinely handle engine component replacements and refurbishment.

Harrowell warns of the potential risk if the industry fails to develop skills for battery refurbishment. As the market grows and the fleet of EVs ages, the frequency of write-offs could become more pronounced. This could make it increasingly difficult for owners to get affordable insurance.

The Debate Over 'Betterment'

A pivotal issue affecting insurers is the concept of 'betterment,’ which refers to the dilemma where replacing a damaged battery with a new one leaves the car in a superior condition compared to its state before the accident. Such outcomes could be interpreted as a form of profit for the owner, challenging traditional insurance norms that aim for fair compensation relative to the vehicle's pre-accident condition.

Harrowell notes that refurbishment to restore a battery to its original, pre-damage state could mitigate many of these challenges. The advancement of repair techniques could lead to less costly insurance premiums for electric car owners.

Progress in Battery Repair Facilities

There are encouraging signs that the industry is starting to adapt. Notably, Cox Automotive and DHL have recently joined forces to launch a center specializing in the repair and remanufacturing of EV batteries for fleets. This facility in Rugby, boasting 35,000 sq ft of space, is designed to process thousands of batteries each year, indicating a positive shift towards a sustainable and efficient battery repair ecosystem.

Paul Stone, managing director at DHL Supply Chain UK, highlighted this initiative as a significant milestone towards establishing a scalable circular economy for batteries in the UK. Such developments could help lower insurance costs by reducing the reliance on new battery replacements.

Companies Leading the Charge on Repairs

Another key player in this emerging sector is Autocraft Solutions, based in Grantham, which specializes in engine remanufacturing and is now also repairing and refurbishing EV batteries. Their approach focuses on restoring batteries to their condition immediately before failure, addressing the betterment concerns of insurers.

Sara Ridley, the engineering and quality director at Autocraft, clarified that while batteries may not return to their exact original state due to chemical changes, their goal is to restore them as closely as possible to their optimal functionality for their age and type. The company is currently able to repair up to 3,000 batteries a year, and each service can offer savings of approximately 50% compared to the cost of a new battery, helping to make repairs a more viable option.

Ridley further points out that a significant number of batteries are sent for scrapping prematurely due to a lack of clarity around their condition and safety. By establishing diagnostic protocols and repair capabilities, her company aims to alleviate insurer concerns and restore confidence in battery repair solutions.

The Future of EV Insurance

With electric vehicle adoption on the rise, it is essential for the automotive industry and insurance sectors to innovate and adapt. Effective battery repair solutions could not only maintain the affordability of EV insurance premiums but also extend the lifespan of electric vehicles on the road. For EV owners, the ability to act quickly and efficiently when faced with battery issues is crucial.
