Introduction

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

Express Plus Components

The Express Plus platform is built from modular components that work together to deliver scalable DC fast charging.

Express Plus modular building blocks

  1. Power Module: Self-contained AC to DC power conversion system that operates an output of between 100 and 1000 V and delivers up to 40 kW of power.

  2. Power Block: Power cabinet that houses up to five Power Modules and supplies DC output power to Power Links. Each Power Block can output up to 200 kW of power. It delivers charging current on two HV DCClosed High Voltage Direct Current buses and provides 48 V DC auxiliary power to connected Power Links. The Power Block and Power Links are also interconnected via Ethernet to support data communications across the system.

  3. Power Link: Dispenser that delivers DC power to EVs through flexible, lightweight charging cables equipped with industry standard connectors. Power Link can accommodate up to two charging cables. Built-in cellular networking enables remote management via the ChargePoint Platform Dashboard.
