Phoenix Contact Energy Storage Solutions

Battery pole connectors are ideal for free wiring and achieve 360° rotation, providing maximum flexibility when it comes to connecting battery poles. Battery connection is protected against polarity reversal by mechanical coding to fight against incorrect coding, and safe installation is possible because the battery terminals are touch-protected even when not plugged in. 

Connectors for busbar connection are plugged into the back of storage systems and are suitable for system voltages up to 1500V. No wiring effort is required during installation due to the plug-in system with an integrated interface.

Utility-Scale Storage

Utility-scale storage systems are utilized as a backup for the grid and allow high peak loads despite inadequate grid infrastructure, i.e., in fast charging stations for electric vehicles. An additional application for large-scale storage systems is the storage or provision of energy depending on the electricity price in energy trading.

Connection Technology for Battery Racks

Every level of energy storage system places different requirements on the electrical connection technology for data, signals, and power. These requirements are covered by the comprehensive portfolio for device and field wiring from Phoenix Contact.

One subsection of the potential requirements is the insulation capability or the resistance to thermal, mechanical, and chemical influences. Other requirements include the bending radii of the conductors or, for example, the number of approvals or cores.

Connection Technology Portfolio for Energy Storage

Energy storage systems are constructed of different components that all contribute to the function of the overall system. The portfolio of PCB connections, connectors, and electronics housing demonstrates strong innovation power. Solutions for data, signal, and power transmission are available for integration into various applications.

Components for Rack BMS Insertion

The rack BMS slide-in module connects to the overall system via a blind-mating feature on the rear, therefore, not endangering the installer. On the front, the individual battery modules of the rack are connected by efficient and user-friendly plug-in connections. Innovative connection technologies for reliable and fast manufacturing processes are used for the internal wiring of signal, power, and data components.

• Board-to-board connectors
• Lever-actuator PCB terminal blocks and connectors
• Feed-through connectors
• RJ45 jacks
• Current transducers
• Battery-pole connectors
• Busbar connectors

Residential Storage

Paired with a photovoltaic system, energy storage devices play a huge role in homes. The proportion of self-generated electrical energy utilized in the household’s electricity consumption is increased significantly. During a disturbance in the public grid, it enables a continuous, self-sufficient supply.

Connectors for the Power Control Unit in the Residential Storage System

The Power Control Unit is the central control element of the residential storage system. It organizes the discharging and charging processes of the battery modules, ensuring their safe operating state. This is achieved because the unit monitors currents, voltages, and the temperature inside the modules.

• Feed-through connectors
• EtherCAT
• RJ45 connectors
• Board-to-board connectors
• DC and AC cabling connectors
• PCB terminal blocks and connectors

Connectors for Residential Storage Battery Modules

Battery modules are the heart of the energy storage systems and contain battery cells in which they electrical charge is stored as chemical energy. Each battery module features cell balancing, ensuring all the battery cells maintain an equal state of charge.

• PCB terminal blocks and connectors
• Modular rectangular connectors
