Electric vehicle (EV) lithium-ion batteries are both a major advantage and a significant hazard to owners and the environment.
Recently, an electric scooter caught fire at a backpacker hostel in Sydney, prompting Catriona Lowe, deputy chair of the Australian Competition and Consumer Commission, to emphasise the dangers of these batteries in an ABC AM interview. Lowe urged for a government-led campaign to raise consumer awareness of lithium-ion batteries, which now power a diverse range of devices.
Furthermore, a battery malfunction in a luxury EV at Sydney’s Mascot Airport led to the destruction of five cars. Interestingly, EV fires, although alarming, are relatively rare, as global data suggests.
The challenge in handling lithium-ion battery fires is highlighted by hagerty.com, a US-based motoring site. They state that these fires require a tremendous amount of water to cool or must be allowed to burn out entirely. This highlights the risks when EV batteries are compromised, even in minor accidents. Consequently, the UK is experiencing a surge in EV insurance premiums, with some reporting increases of up to 1000%.
It’s crucial to note that EV batteries, comprising about half the car’s cost, can be easily damaged in minor accidents. When damaged, these batteries pose a higher risk of catching fire. Unfortunately, most damaged batteries cannot be repaired, leading insurance companies to declare even slightly damaged vehicles as total losses. As a result, piles of discarded battery packs are accumulating in scrapyards in certain countries, especially since the UK lacks battery recycling facilities.
Thatcham Research, the UK car insurance research group, reported that EVs are pricier to repair and take longer than traditional vehicles. They pinpointed high-voltage battery damage claims as a significant challenge, mainly due to the battery’s value.
Despite these concerns, many motoring journalists rarely address these issues. Some industry experts believe there’s insufficient data on EV fires, and thus, the risks are not well understood. They express concerns about EV charging in residential parking areas and potential dangers from spreading toxic chemicals in case of fires.
While it’s still too early to determine the impact of EV repair costs on Australian insurance premiums, factors like part importation costs, scarcity of EV repair centres, and battery disposal challenges are expected to play a role.
Fire and Rescue NSW has initiated a project to research lithium-ion fires and the related risks. The government-supported EVFireSafe.com provides valuable insights into the challenges of controlling such fires.
However, the risk to vehicle owners is just the tip of the iceberg. The bigger concern is the environmental impact of manufacturing, transporting, storing, and disposing of used batteries. Studies indicate that many Western EVs may take up to five years to offset their carbon footprint compared to traditional vehicles, depending on the energy source used to charge them.
China, the world’s largest CO2 emitter, is also the primary manufacturer of most EVs and their batteries. This poses a contradiction: while the West attempts to reduce emissions by promoting EVs, they indirectly support a country with rising emissions.
In the US, despite initial enthusiasm, EV sales have declined, leading to significant price cuts by major manufacturers. Some experts question the overall environmental benefit of EVs, especially when considering the emissions involved in electricity generation and the environmental hazards linked to mining rare earths for batteries.
EVs offer several benefits, such as low maintenance costs and enjoyable city driving experiences. However, users should be cautious about potential battery damages and their broader implications.
