Australian Tech Innovation to Revolutionise EV Charging
Table of Contents
Electric vehicles (EVs) are growing in popularity, but one persistent issue has been managing the strain they place on our power grids, especially in times of high demand. A groundbreaking Australian invention promises to revolutionize the way EVs are charged by harnessing unused power in the grid, providing a sustainable and reliable solution for the future.
This innovation’s core is a patented technology, developed by Professor Geoffrey Chan, Chief Technical Officer at Australian company I-Charge. This breakthrough can potentially solve one of the key problems in EV infrastructure—ensuring enough charging capacity without overloading the grid.
The Technology Behind the Revolution
Professor Chan’s innovation is set to be unveiled at the All Energy Australia conference in Melbourne, with excitement building after his recent Gold Medal win at the prestigious BRICS Innovations Competition. His patented design, registered under US-12119696B2, dynamically adjusts the charging load in real time based on the grid’s available capacity.
This system works by tapping into the unused power—the difference between the historical peak capacity of electrical equipment and the actual power it’s using at any given time. This clever use of underutilized capacity helps to balance the grid without the need for expensive infrastructure expansion.
How It Works: Tapping into Unused Power
The new technology monitors the power consumption of a building or facility on a minute-by-minute basis. When certain appliances or equipment are switched off, the system diverts that unused power to EV chargers. When the equipment comes back online, the technology reduces the power flowing to the EV chargers, preventing overloads.
In simple terms, it allows EVs to charge by dynamically adjusting the available power. This is particularly useful in areas where expanding physical infrastructure, such as adding more transformers or installing new lines, would be cost-prohibitive or physically impossible, such as in densely populated cities or shopping centres.
Benefits for the EV Ecosystem
As EVs become more popular in Australia, concerns about grid capacity have intensified. Professor Chan’s innovation directly addresses these concerns, providing a solution that helps avoid the “grid overload” scenarios that many fear.
Instead of installing expensive new infrastructure to support more EV chargers, this system uses existing resources more efficiently. It is ideal for high-density urban areas where space is limited, and adding physical infrastructure isn’t always an option.
The Impact on Australia’s EV Future
Australia’s EV adoption is on the rise, with more people choosing electric over traditional petrol vehicles. However, this surge in EV use places new demands on the country’s power grid. According to the Australian Energy Market Operator (AEMO), EV uptake could lead to a 10% increase in electricity demand by 2030. Meeting this demand sustainably is a priority.
Why Tapping Unused Power is Crucial
Professor Chan highlights the difference between electric power (measured in kiloWatts) and electric energy (measured in kiloWatt hours). The grid can often deliver more power than is needed at any one moment—this surplus, known as unused power, is what the new technology leverages.
Unused power exists because most electrical generators, except nuclear plants, seldom operate at 100% capacity. By capturing this spare capacity, I-Charge’s system ensures that EV charging is efficient and doesn’t contribute to unnecessary strain on the grid.

| Cost-Effective | Eliminates the need for expensive grid upgrades by using existing infrastructure |
| Sustainable Energy Use | Reduces waste by tapping into unused power resources in the grid. |
| Applicable in High-Density Areas | Ideal for urban environments with limited space for additional infrastructure |
Global Impact | Already being implemented in regions like North America, Hong Kong, and Malaysia. |
A Global Innovation with Local Root
Although Professor Chan’s technology was developed in Australia, its implications stretch far beyond. I-Charge currently operates over 1,000 EV charging sites globally, spanning Australia, North America, Hong Kong, Macau, and Malaysia. According to I-Charge Managing Director, Rosemary Tan, this new patent has the potential to transform EV charging worldwide.
“We couldn’t be prouder of Professor Chan’s work,” Tan said. “This breakthrough technology promises to transform the efficiency and reliability of EV charging across the globe.”
Real-World Implementation: I-Charge’s Global Reach
- Australia: Over 300 charging sites with plans to expand further.
- North America: High demand for intelligent charging solutions.
- Asia: Growing adoption in urban centers like Hong Kong and Macau.
This global expansion reflects the versatility and scalability of the new technology, which can be adapted to different energy markets and grid structures.
Challenges of EV Infrastructure and Grid Overload
The most significant challenge facing widespread EV adoption is grid capacity. Australia’s grid, particularly in metropolitan areas, faces occasional strain even without the added load of widespread EV charging. Many experts worry about how the grid will cope as the number of EVs increases exponentially.
Professor Chan’s solution offers a practical answer to this problem, ensuring that EV drivers can charge their vehicles without causing brownouts or blackouts, even during periods of peak demand.
Future Outlook: A Sustainable and Smart Grid
This invention not only addresses current grid concerns but also paves the way for smarter, more sustainable energy management in the future. As the technology is implemented on a larger scale, it could play a key role in Australia’s energy transition, helping the country meet its renewable energy targets while supporting the shift to electric vehicles.
Conclusion
Australia’s tech innovation in EV charging, led by Professor Geoffrey Chan, is set to transform how we power our vehicles. By tapping into unused power in the grid, this patented solution offers a sustainable, cost-effective, and scalable approach to meet the demands of a growing EV market. With its potential for global impact, this invention marks a significant step forward in Australia’s push toward a smarter, greener energy future.
