Battery-integrated fast charging
Fast chargers paired with on-site batteries, in one unit or as a separate storage system, deliver high charging power from a modest grid connection. We help you decide when it makes sense, size the battery and chargers together, and buy systems that stay reliable for years.
The technology
How battery-integrated charging works
What it is
A battery recharges steadily from the grid between sessions
During a session, chargers draw from battery and grid together
Integrated units combine battery and charger in one product
Separate storage can serve several chargers and the building
What decides performance
Battery energy against your busiest charging window
Grid power available to recharge between sessions
Charger power and what visiting vehicles can accept
Controls that manage battery, grid and chargers together
The complexities
What makes it hard to get right
Technical
Sizing the battery to real session patterns, not averages
Recharge time when sessions arrive in clusters
Battery ageing, warranty terms and capacity over time
Conversion losses in AC- and DC-coupled designs
Practical and commercial
Comparing cost with a grid upgrade over the same period
Planning, fire safety and network approvals for storage
Service for two technologies, often from different suppliers
Savings from peak costs and flexibility that must be proven
Where it fits
When battery-integrated charging is the right answer
A good fit when
A grid upgrade is slow or expensive
Charging peaks are short and predictable
Peak electricity charges are high
A site wants fast charging on its existing supply
Think twice when
High power is needed for most of the day
A quick, affordable grid upgrade is available
There is no data yet on how the site will be used
