New battery technology may not be the solution to EV charging issues, says MGUY Australia

As proponents of electric vehicles (EVs) continue to tout the benefits of new battery technology that promises faster charging times, a recent announcement about 5-minute charging technology has once again sparked excitement in the EV community. However, while this breakthrough may solve the problem of rapid charging, it also magnifies another issue that is often overlooked – the staggering amount of electricity needed from the grid to support such fast charging.

The new lithium sulfur batteries, which are said to charge in less than 5 minutes, are being hailed as a potential game-changer for electric vehicles and other consumer technologies. With the help of a new catalyst made from carbon material and cobalt zinc clusters, researchers have been able to create a battery with large amounts of power that can charge in record time.

But as promising as this technology may be, the infrastructure required to support such fast charging poses a significant challenge. For example, a small 60 kWh battery found in an average EV would require a charging power of 720 kW to charge in 5 minutes – equivalent to the power needed to run 360 kettles simultaneously. This means that a 10-stall charging station providing 720 kW charging would need a supply of 7.2 MW, enough for 1,000 average homes.

The issue of grid capacity becomes even more apparent as charging times decrease. While a fuel filling station can easily accommodate multiple cars pumping from the same tank, the same cannot be said for EV charging stations. The more cars that require fast charging, the more strain it puts on the grid, making it nearly impossible to scale up the infrastructure to meet the demand.

In the end, the reality of EV charging is clear – you can have fast charging or you can have reasonable infrastructure, but you can’t have both. While new battery technology may offer exciting possibilities for the future of electric vehicles, the challenge of supporting rapid charging on a large scale remains a significant hurdle that must be addressed. As we continue to push the boundaries of innovation in the EV industry, finding a balance between speed and sustainability will be key to ensuring the widespread adoption of electric vehicles in the years to come.
