Appendix A – PHI Battery Safety & Green Attributes,

Certifications

This Appendix section covers the PHI Battery safety attributes and certifications, such as the lack of thermal

runaway with fire propagation, off-gassing, UN DOT certification and UL compliance and certification. It also covers

the PHI Battery’s green attributes – from products to materials to disposal, as well as relevant environmental and

ecological considerations.

B.1 – Safety Attributes and Certifications

B.1.1 – Intrinsically Safe Operation and Installation

The PHI Lithium Ferrous Phosphate (LFP) battery cell component is made with an intrinsically safe cathode

material (iron phosphate). This creates a strong molecular bond, which withstands extreme conditions,

prolongs cycle life, and maintains integrity with little or no maintenance over extended periods of time.

There is virtually no danger of Thermal Runaway with fire propagation, as there may be with Lead Acid,

NiCd, and Lithium Cobalt type batteries (NCA, NMC, LCO). No venting or cooling is required. No

precautions or special structural considerations are necessary when installing PHI Batteries.

B.1.2 – No Safety Hazards due to Off-Gassing, Exposure to

Acids, Thermal Runaway

PHI Batteries do not vent dangerous gasses during normal operation, such as hydrogen and oxygen,

because chemicals contained in Lithium Ferro Phosphate cells’ electrolyte do not electrolyze to any

appreciable extent within the PHI Battery’s operating voltage range. In contrast, lead acid batteries which

contain water and sulfuric acid experience significant electrolysis into H2 and O2 during normal operation.

There are no dangers of exposure to sulfuric acid because PHI Batteries do not have caustic electrolytes.

Thermal runaway with fire propagation is not an issue with PHI products due to the basic nature of Lithium

Ferro Phosphate cell chemistry utilized in all our power storage products.

B.1.3 – PHI Battery Control and Protective Circuitry

SimpliPhi Power Inc. utilizes balancing, voltage regulation, thermal and current controls, as well as other

protective measures, in its PHI Battery Management System (BMS). This protective circuitry is embedded in

the architecture of each PHI Battery.

B.1.4 – UN DOT Certified Cells

The Lithium Ferrous Phosphate (LFP) cells are independently certified to withstand the UN DOT 38.3

testing guidelines with no special circuitry added. These tests include short circuit, over-voltage,

overcharging, extreme temperature, high altitudes, shock and extreme vibration testing.

B.1.5 – UL Compliance

The Lithium Ferrous Phosphate cells within the PHI Batteries fully comply with the safety testing

parameters of UL 1642.

B.1.6 – RoHS Compliant

SimpliPhi Power 3.8 Batteries are RoHS compliant. Any RoHS compliant component is tested for the

presence of Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent chromium (Hex-Cr), Polybrominated

biphenyls (PBB), and Polybrominated diphenyl ethers (PBDE). For Cadmium and Hexavalent chromium,
