Introduction
This section provides an introduction to the ChargePoint® Express Plus Power Hub.
Power Hub and Express Plus
The Power Hub is a component of the Express Plus product family. Express Plus is a modular solution for scalable fast charging of electric vehicles, comprising the following product components:
-
Power Block: Power cabinet that converts AC power to DC power. Supplies DC output power to Power Link 1000s, either directly or through a Power Hub. Each Power Block has two DC outputs.
-
Power Hub: Distribution cabinet that enables one or more Power Blocks to distribute charging power to more Power Link 1000s than a single Power Block could support by itself.
-
Power Link 1000: Dispenser for electric vehicles, available in single or dual input variants. Can support up to two output cables or automatic connection devices with sequential or simultaneous charging.
The Power Hub is used in fleet charging architectures. Each Power Hub can accept input power from up to two Power Blocks, and then distribute that power to as many as eight Power Link 1000s (two or four of which can actively charge at a time, depending on configuration). The configuration shown above can charge two vehicles at a time and supports sequential charging of 16 vehicles.
Internal disconnect switches enable high voltage shutoff between the Power Hub and each of its connected Power Blocks. Low voltage and Ethernet connectivity are fed from the Power Blocks to the Power Hub, and from the Power Hub to Power Link 1000s.
