Split charging systems: when a shared power cabinet makes sense

On larger sites, a shared power cabinet feeding several dispensers can beat standalone units on cost and make load sharing easier.

Last updated 15 August 2026

Most people picture a charger as a single all-in-one unit. On bigger depots, though, a split system — where one power cabinet feeds several dispensers — is often the smarter build.

How a split system works

Instead of each charging point containing its own power electronics, the expensive kit lives in a central cabinet, and slim dispensers at each bay draw from it. It’s the difference between many self-contained machines and one engine room feeding several outlets.

Where it wins

Split systems come into their own on larger sites for a few reasons. They can be more cost-effective at scale, because you’re not duplicating power electronics at every bay. They make power sharing easier, since the central cabinet can allocate its capacity dynamically across the dispensers — a natural fit with load management. And they can be tidier and easier to maintain, with the complex equipment in one accessible place.

Where standalone still fits

For a handful of chargers, standalone units are simpler and cheaper to install — there’s no central cabinet to justify. Split systems earn their keep as the number of points grows and power sharing becomes central to the design. It’s a scale decision.

This is the kind of detail your installer will help settle once the bigger choices — AC versus DC, how many points, and the yard layout — are made. Raise it early on larger projects, because it influences where cabling runs and how the civils are dug.
