Compliant systems for high-visibility, high-resilience infrastructure
The release of AS4044:2024 represents a decisive shift in how stationary battery charger systems are specified, validated, and integrated into essential infrastructure. For engineers operating in substation environments, the standard sets a clearer expectation: charger systems must support not only stable DC output, but also traceable compliance, telemetry integration, and environmental hardening.
Where past standards offered baseline safety guidance, AS4044:2024 positions the charger as a frontline infrastructure component — one that is observable, auditable, and embedded in sitewide continuity planning.
Why AS4044:2024 Demands a Different Design Approach
In substation and switching applications, battery chargers are no longer passive backup devices. They are interlocked with control systems, automation logic, and emergency failover protocols — and the cost of misalignment is measured in outages, not inconvenience.
AS4044:2024 introduces requirements that directly address operational reliability and real-world performance in harsh or high-dependency environments. These include:
“The updated standard redefines compliance — moving beyond electrical function into the realm of system accountability, telemetry integration, and lifecycle assurance.”
Building Compliance into the System Architecture
Rather than treating compliance as a retrofit, AS4044:2024 reinforces the need for purpose-designed systems — engineered from the outset to meet performance, monitoring, and integration requirements.
Engineering considerations include:
Intelepower’s site audit and specification process ensures that these considerations are not only engineered into the product — they’re validated against environmental and load profiles before installation begins.
The Role of SCADA Visibility in Compliance
In modern substations, visibility is critical — not just for performance tracking, but for event diagnosis and compliance documentation. AS4044:2024-compliant chargers must operate as native elements in the control topology, not as isolated boxes.
This requires the ability to:
These features reduce operational blind spots and allow the charger to function as a responsive, intelligent component within the substation control ecosystem.
