Introduction

This section defines the purpose of this guide and provides an introduction to the ChargePoint® Express Distro Power Block 2000.

About This Guide

This guide provides instructions for installing the Power Block 2000. It covers preparation requirements, mounting and anchoring procedures, electrical and communication connections, commissioning steps, and verification tasks needed to place the station into service.

This guide is intended for licensed electricians, installation contractors, and construction professionals responsible for installing Power Block 2000 equipment in accordance with local codes and ChargePoint requirements.

This edition of the guide focuses on installing Power Block 2000 in the single‑cabinet, four‑output configuration. Support for double‑ and triple‑cabinet installations, along with eight‑output and twelve‑output configurations, will be incorporated in a later update.

Power Block 2000 Overview

Power Block 2000 is a product within the ChargePoint Express DC fast charging platform. Power Block 2000 is a power cabinet, responsible for AC grid connection, power conversion, and DC power distribution to downstream EVSEs such as external Power Link charging dispensers.

For information on Power Link charging dispensers and other EVSEs in the ChargePoint Express platform, refer to the Express platform documents at ChargePoint Product Reference Documentation.

System Description

The Power Block 2000 intakes 3-phase AC grid power and performs power conversion with two types of modules:

AC Power Module – The AC power module converts AC input power to DC output power. Up to three modules can be installed into each Power Block 2000 cabinet to scale total power capacity.
DC Power Module – The DC power module is an isolated, bidirectional DC/DC converter that conditions power for delivery to downstream EVs.

The Power Block 2000 has two separate DC power distribution buses:

DC Grid Bus – The DC Grid Bus is a non‑isolated DC bus (up to 950 V depending on region and application). Multi-cabinet Power Block 2000s can ship with their DC Grid Buses interconnected for power sharing. DC Grid functionality is supported only on 480 V AC and 400 V AC Power Block 2000 models; 600 V AC models do not support DC Grid.
DC Output Bus – The DC Output Bus is an isolated DC bus (100–1000 V) that delivers regulated output power to connected EVs. Power flow from the DC Output Bus is routed through the Contactor Matrix, which selectively connects to a set of discrete external DC outputs.

The Power Block provides the following external DC outputs:

Power Block 2000 is available with four, eight, or twelve external DC outputs per cabinet, designated EXT A, EXT B, EXT C, and so on through EXT L.
Each output can supply power to a single input power path of a Power Link charging dispenser.

The Power Block 2000 is equipped with an Auxiliary Power Supply (APS) system:

Auxiliary Power Supply (AUX PS Auxilary Power Supply) Modules – Each cabinet includes AUX PS Auxilary Power Supply modules that generate 48 V DC power for internal electronics and sub-assemblies within the unit.
48 V DC Output – Each Power Block 2000 cabinet provides 48 V DC outputs for supplying power to connected Power Link charging dispensers.

The Power Block 2000 features an integrated system that facilitates safe and reliable communication and control:

Power Management Controller (PMC) – The PMC controls power flow within the system. It communicates with the power converters and the contactor matrix to manage the delivery of power to the external DC outputs. The PMC supports Ethernet ports for communication with various components like connected Power Link charging dispensers and interconnected Power Block 2000 cabinets to ensure seamless operation. In the event of a fault, the PMC can instruct the power converters to stop power delivery and open the contactors to isolate the power source.
Contactor Matrix – The contactor matrix receives commands from the PMC to open or close the contactors as needed.
Safety Hub Board (SHB) – In addition to processing fault reports from the Neutron, the SHB supports four dispenser ports for performing continuous electrical isolation monitoring of connected Power Link charging dispensers. Any faults detected are reported to the PMC.

System Interfaces and Sample Architecture

The following provides a high-level overview of the electrical interfaces of a Power Block 2000. The diagram also illustrates the interconnections required for an example architecture in which the Power Block 2000 provides DC output power to the input power paths (A and B) of two Power Link 2000s. The Power Link 2000s are each equipped with two charging cables (L and R). Note that Power Link 2000 does not require Safety Hub (SH) monitoring.

IMPORTANT:Power Block 2000 can be configured in many different system architectures, only one of which is shown above. The actual architecture for each site will vary depending on the number of stations, the charging capacity required at each charging station, charging requirements, and other criteria. If you are a site designer, contact a ChargePoint representative for the ChargePoint-approved wiring architecture for your specific project. Systems configured with non-approved wiring between Power Block 2000 and paired stations may not function as expected. If you are an installer, see the site plan for the architecture specific to the site installation project.
