# [FMECA in Energy Storage Tech Brings Value-Added Maintenance Strategies](https://blog.nexusglobal.com/fmeca-in-energy-storage-tech-brings-value-added-maintenance-strategies)

Nexus Global partnered with the largest producer of solar energy storage systems to develop **FMECA** and [deploy value-added maintenance strategies](https://www.nexusglobal.com/apmsolutions/strategy-management)for a new product generation. Using **Strategy Optimizer™**, risk-based tasks were standardized and rapidly rolled out across like assets—improving reliability and time-to-value.

 

## Why FMECA Matters for Battery Energy Storage (BESS)

Launching a new energy-storage generation requires [structured risk analysis (FMECA) and deployable maintenance strategies](https://www.nexusglobal.com/strategyopt) across cells, modules, packs, PCS/BMS, and cooling—so availability and safety scale with production.

 

## Engagement Scope

#### **Build System/Component FMECAs (Cells → Packs → PCS/BMS → Cooling)**

- Severity, occurrence, detectability scoring
- Focus on BMS/thermal management and interconnects

#### **Convert Critical Modes to Tasks**

- Value-added tasks: inspections, condition-based checks, redesign triggers
- Intervals and triggers tied to risk and operating context

#### **Rapid Deployment with Strategy Optimizer™**

- Template, version, and deploy strategies to like assets
- Maintain governance with change logs and approvals

## Results & Expected Impact

Clearer maintenance rationale, faster strategy roll-out, improved reliability and safety posture, and better warranty decision-making via standardized closeout data.

> “It’s exciting to be at the forefront of a client’s new product release and to finally work with an OEM (Original Equipment Manufacturer) that wants to provide the best strategy portfolio to a client. As opposed to a book of OEM recommendations that carry a high cost for the clients to execute and no alignment to failure modes,” explains Nexus Global CEO/President Larry Olson. “I believe the end-users of this product will really appreciate the extra effort this company has put into product care to assure reliability, as well I am positive the warranty claims will be low, which leads to a win/win.”

## Lessons for OEMs & Integrators

- Treat BMS/thermal modes as top-of-stack risk
- Keep code sets and task libraries short, curated, and owned
- Close the loop: feed field findings back into FMECA and task intervals quarterly
