a provider of lithium-ion batteries, modules and packs. Valence differentiates its lithium-ion products through its cathode (positive terminal in discharge) material, a lithium iron magnesium phosphate (LiFe 1-x Mg x PO 4 ). The USCAR/DOE long term goal is 5,000 cycles. The Edison is a 3.5 gallon in January 2009.

Even with current lithium-ion technology, EV batteries showcase impressive durability and sustained energy retention. However, an electric car’s lithium-ion battery may last as long as the vehicle itself. Battery technology monitors the battery State of health (SoH), indicating degradation and remaining capacity.

It’s fairly well known by now that EVs cost far less per mile to drive than their closest ICE counterparts, and the main reason is simply that the EV drivetrain is far more efficient at converting its stored form of energy into motion. For example, that allowed 3% voltage drop on a 240 VAC nominal circuit is 7.2
