Battery-Buffered Chargers Break EV's Biggest Infrastructure Barrier

BRIGHTON, Australia – April 09, 2026 – A Penske Automotive Group dealership in Brighton has become a proving ground for a technology that tackles one of the biggest obstacles to electric vehicle adoption: the limitations of the existing power grid. In a collaboration between German battery specialist ADS-TEC Energy and its Australian partner Elanga, an ultra-fast charging station was installed and operational in less than 24 hours, boosting the site's charging power more than fivefold without the need for costly and time-consuming electrical grid upgrades.

The installation demonstrates a powerful solution to a problem plaguing EV infrastructure developers worldwide. The dealership previously operated a 150 kW DC fast charger, but its performance was severely restricted by the local grid's limited capacity. By swapping it for ADS-TEC Energy’s battery-buffered ChargePost system, the site can now deliver charging speeds up to 300 kW. Shortly after commissioning, the system was observed delivering 281 kW to a customer's vehicle—a level of performance previously unattainable at the location.

The Grid Bottleneck Breached

The secret lies in the ChargePost’s integrated battery storage. The system draws power from the grid at a modest rate—as low as 22 kW—and stores it in its internal lithium-ion batteries, which have a capacity of up to 201 kWh. When an EV plugs in, the charger unleashes this stored energy at ultra-fast speeds, effectively bypassing the grid's limitations. This “boost” function allows a location with a low-power connection to offer a high-power charging experience comparable to sites with massive, dedicated grid infrastructure.

This technology directly addresses the high costs and long delays associated with traditional grid expansion. The all-in-one, compact design of the ChargePost, which occupies less than two square meters, integrates the battery, power electronics, and charging columns into a single unit. This allows for a swift installation process using a forklift and a simple connection to the existing low-voltage grid, as evidenced by the sub-24-hour deployment in Brighton.

“Penske represents high-performance vehicles and demanding customers. This makes the location a perfect fit for our technology,” said Thomas Speidel, CEO of ADS-TEC Energy, in a statement. “We are proud to support Penske together with our partner Elanga. Our battery-buffered fast charging enables ultra-fast charging even where grid capacity is limited – exactly the kind of solution many dealerships need as electric vehicles become more powerful.”

A Multi-Billion Dollar Problem Meets an All-in-One Solution

The challenge faced by the Penske dealership is far from unique. Across the globe, the rapid growth of the EV market is outstripping the capacity of aging electrical grids. A 2024 industry survey revealed that a staggering 75% of EV charging station developers and operators consider grid limitations a major obstacle. The process of upgrading a grid connection can be prohibitively expensive, with some businesses facing quotes exceeding half a million dollars, and can involve delays of 18 months or more due to utility backlogs and equipment shortages.

This infrastructure bottleneck threatens to slow the transition to electric mobility. Battery-buffered charging systems have emerged as a critical enabling technology to circumvent this problem. By decoupling the charging speed from the grid's immediate capacity, companies like ADS-TEC Energy, and competitors such as FreeWire Technologies and SparkCharge, are providing a much-needed shortcut. This approach not only accelerates deployment but also helps site operators avoid permanently higher grid fees associated with an expanded connection.

ADS-TEC Energy’s technology has already garnered significant industry recognition, earning the German Innovation Award and a Red Dot Design Award in 2024. These accolades highlight the system's innovative approach to solving a fundamental infrastructure challenge, combining high performance with a compact, aesthetically integrated design that even includes optional 75-inch digital displays for advertising or information.

Dealerships on the EV Frontline

For automotive dealerships, the transition to EVs presents a unique set of operational challenges. As manufacturers roll out more powerful electric models, dealerships are often mandated to provide high-speed charging capabilities. The Penske installation showcases the immediate business case for battery-buffered solutions in this sector.

Ultra-fast charging dramatically improves operational efficiency and customer experience. It allows for rapid vehicle preparation before customer handover, quick top-ups during service visits, and impressive charging demonstrations for prospective buyers. For a premium brand portfolio like Penske's, delivering a seamless and high-performance charging experience is essential to maintaining brand standards.

Penske Automotive Group has been actively investing in its EV infrastructure as part of a broader strategy to embrace electrification. The choice of a battery-buffered system in Brighton signals a strategic move to deploy best-in-class charging capabilities quickly and cost-effectively, ensuring its facilities are future-proofed for the next generation of EVs without being dependent on slow-moving utility upgrade timelines.

Australia's EV Infrastructure Gets a Blueprint for Growth

The Brighton installation serves as a significant milestone for Australia's burgeoning EV market. While EV sales are on the rise, the rollout of public fast-charging infrastructure has struggled to keep pace, particularly in regional and remote areas. As of mid-2022, the country had fewer than 3,500 public charging stations, with only a fraction offering true fast-charging speeds.

The partnership between ADS-TEC Energy and Queensland-based Elanga, a specialist in EV charging solutions, provides a powerful template for accelerating infrastructure deployment across the continent. Elanga’s local expertise in electrical systems and project implementation, combined with ADS-TEC’s advanced technology, allows for the rapid establishment of high-power charging hubs in locations previously deemed unsuitable.

This model is not only relevant for urban dealerships but also holds immense potential for expanding Australia's charging network along major highways and into rural communities where grid infrastructure is often weaker. By enabling ultra-fast charging without massive capital investment in the grid, this technology can help bridge the infrastructure gap and give more Australian drivers the confidence to make the switch to electric. This successful deployment is a clear signal that the future of EV charging may rely less on waiting for the grid to catch up and more on intelligent, battery-powered solutions that bring the power to where it's needed most.
