Prevent costly battery failures before they happen

Built for preventive maintenance, improved productivity and full compliance with IEC/EN 60255-1, the BA9054 is a powerful, compact solution for safeguarding battery storage systems. Available in three configurations the BA9054 is engineered for high-precision voltage detection, identifying imbalances with exceptional repeat accuracy.

By detecting irregularities early, it enables engineers to take corrective action - reducing maintenance downtime, preventing system disruptions, and ensuring peak battery efficiency.

Battery systems play a mission-critical role in energy storage, backup power - including UPS systems for data centres and in-house IT depts - and other industrial applications. To prevent operational failures, voltage symmetry monitoring is essential.

In backup power systems composed of multiple battery packs, a single underperforming cell can reduce the total available energy, trigger shutdowns and compromise power delivery when it's needed most. Worse still, it can dictate the reliability of the entire battery pack, leading to reduced efficiency or catastrophic failure.

The roots of the problem

Discharge Limitation: Discharging must stop when the first cell is depleted, even if other cells still hold charge. Continuing would damage the depleted cell and shorten overall battery life.

Charging Limitation: Charging must stop when the first cell reaches its maximum voltage. Exceeding this can lead to thermal runaway, posing a risk of catastrophic failure, including fire or explosion.

Battery symmetry monitoring is essential for catching these issues before they cause lasting damage.

"In systems where just one cell can limit energy availability and jeopardise power delivery, the BA9054 empowers design engineers to add advanced battery health monitoring for reliable performance without complicating system design," said Ian Holland, DOLD Managing Director.

"With gold-plated contacts for reliable low-load switching, LED indicators for real-time feedback, and a compact 45mm width, it seamlessly integrates into existing battery management systems."

DOLD's BA9054 is purpose-built for design engineers working in battery storage, renewable energy, and industrial power systems. By integrating this device into their designs, engineers can improve battery efficiency, prevent system failures, and optimise energy usage - ensuring a stable, reliable power supply is always available when and where it's needed most.
