The Enertia uses six Lithium Phosphate battery modules built by Valence Technologies, Inc. in Austin, Texas.  Representing the latest in battery technology, this battery chemistry provides both an amazing life cycle and inherent safety not found in other Lithium-Ion batteries.  These six individual modules are in constant communication with each other and the Battery Management System (BMS), which serves a “big brother” function making sure all the battery levels and temperatures are in check.The BMS is roughly equivalent to the ECU in an internal combustion engined vehicle.  The main difference being – instead of controlling ignition, spark and cam timing, and metering fuel – it’s busy keeping an eye on the current being delivered from the batteries to the controller and the state of charge of each cell to ensure that none of the six modules gets out of balance.  The BMS also controls the charging cycle to ensure each battery module gets just the right juice to end up with a fully charged and balanced battery pack.

From the Valence Website:  

“The safety characteristics inherent to Valence’s Saphion® battery technology result from the incorporation of phosphates as the cathode material. Phosphates are extremely stable in overcharge or short circuit conditions and have the ability to withstand high temperatures without decomposing. When abuse does occur, phosphates are not prone to thermal runaway and will not burn. As a result, Saphion® technology possesses safety characteristics that are fundamentally superior to those of Lithium-ion batteries made with other cathode materials.
Valence’s Saphion® technology does not contain any heavy metals and does not exhibit the “memory effect” of Nickel-Cadmium and Nickel-metal Hydride solutions. Saphion® technology demonstrates excellent shelf life, long cycle life and is maintenance free.
The advantages of traditional Lithium-ion coupled with the safety features of phosphates, make Saphion® technology the Lithium-ion technology for the future. Valence’s Saphion® Lithium-ion technology utilizes natural, phosphate-based material and offers the greatest combination of performance, safety, cost, reliability and environmental characteristics.”
