Introduction

This section provides an introduction to the ChargePoint® Express Plus with Power Block.

Express Plus Components

Express Plus is a scalable DC fast charging platform. It consists of Power Block and Power Link.

1. Power Block contains Power Modules, which convert the upstream AC power into DC power. A Power Block can accommodate up to five Power Modules, each of which can output up to 40 kW of DC power. Power Block provides the charging current on two HV DC High Voltage Direct Current buses. It also provides 48 V DC power and Ethernet to connected Power Links.

2. Power Link receives HV DC High Voltage Direct Current power from Power Block to charge a vehicle. It can be installed with one or two charging cables. With two cables, it can simultaneously charge two vehicles.

From simultaneous charging of two vehicles at up to 500 kW from single station and sequential charging of six or more vehicles, Express Plus can be configured to meet various charging needs. Multiple Power Blocks and Power Links can be interconnected in many ways with HV DC High Voltage Direct Current wires for charging current, Ethernet cables for network communications, and 48 V DC wires to power the electronics in Power Link. The illustration above shows a sample wiring between single Power Block and Power Link.

For full specifications and certifications, refer to the Express Plus Datasheet at ChargePoint Product Reference Documentation.

Wires Entry

• Stub-up entry: The wires can be entered into the Power Block from the bottom side through conduits or armored cables laid underground.

• Surface entry: At sites where the wires cannot be laid underground, they can be entered into the Power Block from the rear side through wireways or armored cables laid above ground.
