Li-Ion Advantages over Lead Acid
Higher Cell Voltage – Lithium Ion = 3.2 V vs. Lead Acid = 2.0 V – Fewer cells enhances reliability
Considerably Lighter in Weight – Saving transportation cost especially if a helicopter is required.
Much Smaller Footprint – Uses only a fraction of the space required by Lead Acid. – Reduces enclosure and site land cost.
Tolerates Higher Temperatures – Saves energy and equipment costs by eliminating air conditioning requirement.
Faster Recharge Time with Higher Charging Efficiency – Reduces solar array size and generator fuel consumption.
Twice the Discharge Cycle Life – Reducing Operating Costs.
Deeper Discharge Tolerance in Cycling – 70% of the amp hour rating for Lithium Ion vs. 20% for Lead Acid.
State of Health and State of Charge is Monitored – For improved reliability.
Longer Service Life – Li-Ion 6-8 years vs. Lead Acid 2-4 years.
Polar Power is now providing Lithium Ion Iron Phosphate Batteries with its Power Systems. Polar DC Generators can monitor charging and discharging of Lithium Ion Batteries on a cell by cell basis using an advanced Battery Manangment System (BMS).
