5.1.2 – No Safety Hazards due to Off-Gassing,
Acids, Thermal Runaway
PHI 3.5 Batteries do not vent dangerous gasses, such as hydrogen and oxygen, because there
are no chemicals used in the creation of the electrical energy, in contrast to Lead Acid and other
battery chemistries. There are no dangers of exposure to sulfuric acid because PHI 3.5 Batteries
do not have caustic electrolytes. Thermal runaway 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.
5.1.3 – PHI 3.5 Battery Control and Protective Circuitry
SimpliPhi Power Inc. utilizes balancing, voltage regulation, thermal, current controls, as well as
other protective measures, in its PHI 3.5 Battery Management System (BMS). This protective
circuitry is embedded in the architecture of each PHI 3.5 Battery.
5.1.4 – UN DOT Certified Cells
The Lithium Ferrous Phosphate (LFP) cells are independently certified to withstand the UN DOT
T1-T8 testing guidelines with no special circuitry added. These tests include short circuit, over-
voltage, overcharging, extreme temperature, high altitudes, shock and extreme vibration testing.
5.1.5 – UL Compliance
The Lithium Ferrous Phosphate cells within the PHI 3.5 Batteries fully comply with the safety
testing parameters of UL 1642.
5.1.5 – RoHS Compliant
SimpliPhi Power 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, there must be less than 0.01% of the substance by weight at raw
homogeneous materials levels. For Lead, PBB, and PBDE, there must be no more than 0.1% of
the material, when calculated by weight at raw homogeneous materials. Any RoHS compliant
component must have 100 ppm or less of mercury and the mercury must not have been
intentionally added to the component. In the EU, some military and medical equipment are
exempt from RoHS compliance.
Section 5.2 – Green Attributes, Environmental and Ecological
Considerations
5.2.1 – Materials
The primary materials (lithium, iron, phosphate) that make up PHI 3.5 Batteries are
environmentally benign and pose very few polluting or environmentally degrading by-products in
the harvesting and refinement processes. This is especially true when compared to those of lead
acid, NiCad, and NiMH batteries.
5.2.2 – By Products
There are no toxic by-products associated with the assembly or use of PHI 3.5 Batteries, such as
off-gassing hydrogen, sulfuric acid spillage, lead contamination, or explosive chemicals.
