Australia’s push into electric vehicles (EVs) has accelerated rapidly, with government incentives, falling battery costs, and rising emissions concerns driving demand. Yet, as fleets of EVs flood the roads, so too does the need for rigorous auditing to ensure safety, efficiency, and compliance. Without proper oversight, the transition risks exposing vulnerabilities—from battery degradation to charging infrastructure gaps. For businesses and regulators alike, the question isn’t just whether to adopt EVs, but how to audit them effectively to avoid costly failures down the line.

Current auditing practices for EVs are still evolving, often relying on traditional methods adapted for a new technology. This approach risks overlooking critical aspects like thermal management, software updates, and long-term performance. For instance, a study by the see here found that 32 per cent of EV battery audits missed defects in cooling systems, which can lead to thermal runaway—a dangerous condition where batteries overheat uncontrollably. The challenge isn’t just technical; it’s also regulatory. While Australia has introduced new standards like the National Electric Vehicle Strategy, enforcement remains inconsistent across states, leaving gaps for non-compliant vehicles to slip through.

Key Auditing Gaps and What’s Missing

The core of the problem lies in three critical areas: battery health monitoring, charging infrastructure audits, and third-party verification. Most EVs today lack real-time diagnostics that track battery degradation over time, meaning owners and fleet operators often don’t know until it’s too late that a battery is failing. For example, Tesla’s Supercharger network, while extensive, lacks independent audits to ensure all stations meet safety standards. This creates a risk for users who may not realise a faulty charger could pose a fire hazard. Meanwhile, state-based EV registration systems vary widely in their scrutiny of vehicle history—some require full service records, while others don’t, creating an uneven playing field.

Another critical oversight is the lack of standardised testing protocols for software updates. Many EVs now rely heavily on over-the-air (OTA) updates, which can introduce vulnerabilities if not audited properly. A 2023 incident with a Chinese EV maker’s OTA update triggered a recall after reports of unintended acceleration, highlighting how software audits must be as rigorous as hardware inspections. Without clear guidelines, manufacturers and auditors struggle to balance innovation with safety.

• Only 15 per cent of Australian EV batteries undergo third-party certification before sale, compared to 70 per cent for internal combustion engine vehicles.
• Charging infrastructure audits in Australia are voluntary, with no national standard for safety inspections of public chargers.
• Battery degradation tracking in EVs is still largely manual, relying on manufacturer-reported data rather than independent third-party testing.
• State-based EV registration systems vary; some require full service history, others do not, creating compliance inconsistencies.
• Only 20 per cent of EV fleets in Australia have dedicated battery health monitoring systems in place.

The Path Forward: How Auditing Can Catch Up

To address these gaps, a multi-pronged approach is needed. First, governments must mandate third-party battery audits before vehicle sale, requiring independent testing for thermal stability, fire risk, and longevity. This would mirror the strict certification processes already in place for hybrid and petrol vehicles. For charging infrastructure, a national audit program could enforce regular inspections of public chargers, with penalties for non-compliance. The Australian Competition and Consumer Commission (ACCC) has already taken steps in this direction, but enforcement needs to be stronger. Additionally, industry collaboration between manufacturers, auditors, and regulators could develop standardised software audit protocols, ensuring OTA updates are scrutinised for security and functionality.

Fleet operators also play a crucial role. Many businesses are already investing in EV fleet management software that tracks battery health, but adoption remains low. To accelerate this, incentives could be introduced—such as tax breaks for fleets that implement rigorous battery monitoring systems. Public awareness campaigns could also educate drivers on the importance of regular EV audits, much like the campaigns that promoted safety checks for traditional vehicles. Without collective action, the benefits of EVs—from reduced emissions to lower fuel costs—will remain constrained by the hidden risks of poor auditing.

Lessons from the Global Stage

Other countries offer valuable lessons. The European Union’s strict EV certification process, which includes mandatory third-party testing for battery safety, has reduced fire incidents by 40 per cent in the past five years. Meanwhile, Norway’s robust fleet auditing system ensures all EVs meet strict performance standards before registration, leading to one of the highest EV adoption rates globally. Australia could learn from these models by adopting a tiered approach—mandating basic safety checks for all EVs while offering enhanced audits for high-risk models or fleets. This would create a tiered system where compliance is both enforceable and adaptable to emerging risks.

The transition to EVs is not just about the vehicles themselves; it’s about the systems that support them. Without proper auditing, the promise of a cleaner, more efficient transport network could be derailed by preventable failures. The time to act is now. As the number of EVs on Australian roads grows, so too must the auditing standards that protect them—and the people who use them.
