EBOSS® Battery Safety Statement

A clear overview of EBOSS battery chemistry, built-in safety measures, and compliance context.

Summary 

ANA’s EBOSS® systems are built with safety-first battery technology and UL-listed/recognized electrical control, power, and safety components. EBOSS uses Lithium Titanate Oxide (LTO) lithium-ion chemistry, which is significantly less energy-dense than many traditional chemistries—helping reduce the likelihood of fire propagation during thermal runaway.

EBOSS® Battery Safety Design

UL-listed and recognized components

EBOSS® battery safety includes UL-listed and UL-recognized electrical control, power, and safety components to support safe operation in real-world environments.

Why LTO chemistry matters

EBOSS® uses a lithium-ion chemistry called Lithium Titanate Oxide (LTO). Compared with higher energy-density chemistries, LTO’s lower energy density helps significantly lower the chance of fire propagation during thermal runaway.

Battery cells used in EBOSS®

For EBOSS battery safety, ANA uses Toshiba LTO batteries and references safety performance testing such as nail penetration, crush, and overcharge tests.

Energy Storage System Compliance Context (UL 9540 / IFC 2021)

UL 9540 is a requirement for Energy Storage Systems (ESS) released in 2020, and IFC 2021 Section 1200 states ESS systems must comply and be certified to UL 9540.

For ESS products containing lithium-ion technologies, IFC 2021 Section 1207.1.1 specifies that systems up to 20 kWh of energy capacity are exempt from UL 9540 in both mobile and stationary applications.

ANA EBOSS™ (EBOSS70-40, EBOSS70-45) contains 20 kWh and is therefore within the exemption threshold, while still being field evaluated and tested for UL 9540 compliance.

Testing and Certifications (EBOSS® / Toshiba Modules)

ANA EBOSS® references the following safety testing and certifications:

  • UN 38.3 (Toshiba Report ID No. 5T4E0095)

  • UL 1973 (Toshiba Intertek Listing No. 5000741)

  • UL 9540A (including references for Toshiba cells, modules, and UPS unit testing files/reports)

  • UL 9540: ANA Energy BOSS70 using identical Toshiba battery modules (noted as in process)

  • All electrical components are UL listed or recognized
