Engineered for long life, structural robustness, and thermal stability in modern commercial and utility infrastructures.
Navigating compliance, thermal safety requirements, and electromagnetic compatibility for European markets.
For industrial operators, engineers, and supply chain directors, integrating lithium-ion energy storage systems (ESS) requires deep regulatory adherence to mitigate hazard risks. In the European Economic Area, the **CE (Conformité Européenne) marking** is not a simple marketing label; it is a legally mandated conformity declaration. For lithium iron phosphate ($LiFePO_4$) and general lithium-ion storage batteries, a CE marking guarantees that the product complies with core safety and environmental directives.
CE certification for lithium storage systems is divided into several directives, each addressing distinct physical and electrical characteristics of the battery pack and its associated battery management system (BMS):
| Regulatory Standard | Focus Area | Key Testing Metrics | Mandatory in EU |
|---|---|---|---|
| EN 62619 | Industrial Cell & Pack Safety | Thermal abuse, short-circuit, impact, drop, overcharge | Yes (De-facto Requirement) |
| LVD 2014/35/EU | Electrical Insulation & Creepage | Withstand voltage, high voltage breakdown limits | Yes (For >75V DC packs) |
| EMC 2014/30/EU | BMS Radiated/Conducted Emissions | Electrostatic discharge (ESD), surge immunity | Yes (For active BMS packs) |
| UN 38.3 | Global Transportation Safety | Altitude simulation, vibration, impact, thermal cycling | Yes (Required for shipping) |
Note for Design Engineers: True CE compliance requires both component-level (cell and BMS) and system-level verification. Using CE-marked prismatic cells within a custom chassis does not yield a CE-compliant final pack unless the complete assembly is tested under structural load, vibration, and thermal limits.
Excellence in lithium battery design and manufacturing since 2009.
Founded in 2009, Hangzhou LIAO Technology Co., Ltd. is a leading manufacturer specializing in Lithium Iron Phosphate ($LiFePO_4$) batteries.

Advancing cell energy density, safety metrics, and intelligent battery systems.
Our research and engineering efforts focus on improving the electrical efficiency and safety parameters of our battery cells. LIAO's technical roadmap outlines key advancements across four main areas:
We continue to refine our chemistry formulations to prevent internal thermal runaway. Our cells are engineered with ceramic-coated separators and thermal shutdown layers to isolate internal faults under mechanical crush or puncture stresses.
Our battery management systems are shifting to cloud-enabled IoT interfaces. Future integrations will feature predictive safety algorithms, real-time internal resistance profiling, and localized temperature tracking using remote sensor arrays.
To support high-latitude regions, we design formulations capable of operating down to -40°C without sacrificing cycle life. This is coupled with passive heat sink casings and internal pre-heating elements powered by the BMS.
Through systematic developments in electrode structure, electrolyte composition, and automated pack structural engineering, LIAO targets long cycle life (approaching 3500+ cycles at 100% DoD) for commercial grid-tied storage systems and heavy-duty electric vehicle platforms.
Custom-engineered battery solutions tailored to your application's physical envelope and load characteristics.
Every application has unique constraints, including spatial limitations, mechanical shock requirements, charge profiles, and ambient environmental conditions. A pre-built catalog model may not always meet these requirements. LIAO's R&D team works closely with your engineering departments to customize electrical characteristics, thermal management profiles, communication protocols, and structural casings.
Our sales and engineering teams bring deep battery design expertise, providing advice on cell matching, mechanical stress containment, and local regulatory requirements for rapid, successful market integration.
Our OEM/ODM process is structured to save you time and development costs, helping you bring products to market quickly. We manage the design process from initial CAD modeling and BMS programming to prototype testing and certifications.
