A battery-buffered ultra-fast charger is an electric vehicle charging station that uses an on-site battery to store and supply power, allowing cars to charge very quickly without drawing huge bursts of electricity from the grid. Think of it like a water tank that smooths out pressure spikes so multiple hoses can fill fast without straining the main supply. For investors, it matters because it reduces utility upgrade costs, increases throughput and uptime at charging sites, and can cut energy costs by charging the buffer when electricity is cheaper.
dc fast chargertechnical
A DC fast charger is a high-speed electric vehicle charging station that sends power directly into a car’s battery so it can recharge much faster than a standard home or public outlet — think of it as a highway fuel pump for electric cars. Investors watch deployment of these chargers because faster, widely available charging makes electric vehicles more convenient, boosting vehicle sales, increasing revenue opportunities for charging networks and utilities, and influencing the value of related infrastructure and real-estate assets.
grid capacitytechnical
Grid capacity is the amount of electricity the power network can carry, deliver and accept at a given point without overloading — like the width of a highway that determines how many cars can move at once. It matters to investors because limited grid capacity can block new power projects, cause curtailment of energy (especially from renewables), raise connection or upgrade costs, and affect the timing and returns of energy and utility investments.
battery storagetechnical
Battery storage is a system that stores electricity in large rechargeable batteries so power can be used later, like a reusable fuel tank for the grid. Investors care because it smooths out when energy is available vs. when it’s needed, can lower costs, create new revenue from selling stored power at peak times, and reduce reliance on unpredictable energy sources, affecting utility and clean-energy company valuations.
charging outputstechnical
Charging outputs describe the amount of electrical power a charger or charging station delivers to a battery, usually expressed in watts or by indicating voltage and current. For investors, higher or more efficient charging outputs mean faster charge times, better user experience, and potential competitive advantage for products or networks—similar to how a wider garden hose fills a bucket faster, enabling more usage and potentially higher sales or utilization.
energy management functionstechnical
Energy management functions are the tools and processes a business uses to monitor, control and optimize how it uses power—everything from smart meters and sensors to software that schedules equipment and adjusts settings. Like a building’s thermostat combined with a financial dashboard, these functions reduce costs, lower waste, help meet regulations and improve sustainability metrics, which can boost margins and reduce operational risk for investors.

Battery-buffered ultra-fast charger at a dealership of Penske Automotive Group in Brighton, Australia
Battery-buffered system enables ultra-fast charging despite limited grid capacity
ChargePost installed in less than 24 hours at Penske dealership in Brighton
Charging power at the side increased more than fivefold
BRIGHTON, Australia & NÜRTINGEN, Germany--(BUSINESS WIRE)--
ADS-TEC Energy PLC (NASDAQ: ADSE) together with its partner for operations, service and distribution, Elanga, has installed a battery-buffered ultra-fast charger at a dealership of Penske Automotive Group in Brighton, Australia. The installation demonstrates how high-power charging can be deployed quickly even at locations with limited grid capacity.
The site previously operated a conventional 150 kW DC fast charger whose performance was downgraded and restricted by the available grid connection. By installing ADS-TEC Energy’s ChargePost system, charging power at the site was increased more than fivefold without the need for costly grid expansion. The installation was completed in less than 24 hours. Shortly after commissioning, the system delivered a charging power of 281 kW to a customer vehicle.
For the dealership, the new system enables significantly faster charging during vehicle handover, service visits or customer demonstrations. At the same time, the integrated battery storage allows high-power charging while keeping the grid connection unchanged.
“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. “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.”
This is made possible by ChargePost’s battery-buffered technology: a comparatively low grid input of around 22 to 87 kW can be boosted by the integrated battery system to charging outputs of up to 300 kW. This makes it possible to operate high-power chargers even at locations with limited grid capacity.
Beyond fast charging, the ChargePost system also integrates digital advertising displays and intelligent energy management functions. This turns the charger into a multifunctional tool: site operators can create additional revenue streams, optimize electricity costs via the integrated battery and deliver high-power charging without the high costs and long lead times associated with grid expansion. In addition, operators avoid higher grid fees that would permanently apply with an expanded grid connection.
