Supporting compliance and performance in mission-critical environments.
The recent update to AS4044, Australia’s standard for stationary battery chargers, introduces a more rigorous and relevant framework for the design and deployment of DC charging systems. These changes reflect the critical role chargers now play in infrastructure environments where continuity, control visibility, and verified performance are non-negotiable.
This shift recognises the evolving role of battery chargers—not just as passive support systems for energy storage, but as integrated elements of control environments, automation logic, and emergency power continuity. When combined with services like detailed site audits and long-term asset planning, these systems become central to operational resilience. As expectations for uptime, system visibility, and compliance increase, the charger must now demonstrate more than electrical stability. It must prove traceable compliance, data accessibility, and system-level resilience.
Key changes to support high-dependency systems
AS4044:2024 establishes clearer performance requirements tailored to the operational realities of sectors such as utilities, transmission networks, transport infrastructure, and industrial control systems—all of which rely on uninterrupted DC support for operational continuity and safety.
Among the most critical requirements are:
The standard positions FAT not as an optional layer of quality assurance, but as a core compliance mechanism that ensures all systems meet real-world operational demands prior to commissioning.
“The charger must now demonstrate more than electrical stability. It must prove traceable compliance, data accessibility, and system-level resilience.”
Designing with compliance as the starting point
Compliance with AS4044:2024 is most effectively achieved through purpose-built architecture—not post-facto adaptation of general-purpose charger systems. From design through deployment, the system must align with standard requirements across electrical, mechanical, and control domains.
Engineering considerations now routinely include:
Pre-deployment site assessments play a vital role in aligning system design with actual site conditions—ensuring compatibility, thermal management, and optimal load planning before installation begins. When engineered to these specifications, the charger operates not as a peripheral asset, but as a critical, network-visible control component
SCADA integration and control observability
The importance of seamless SCADA integration cannot be overstated. In modern infrastructure environments, telemetry is not a luxury—it is a compliance and operational necessity. Systems must not only deliver power, but also provide real-time performance data, alarm states, and fault escalation logic back to a central control room.
Proper SCADA-aligned charger systems will:
This allows engineering and operations teams to monitor, diagnose, and respond to charger system behaviour within their existing asset management and telemetry frameworks.
