ybrid Vehicle (HV) Battery Assembly (2012 Model)
The Prius Plug-in hybrid features a large capacity high voltage Hybrid
Vehicle (HV) battery assembly that contains newly developed sealed
Lithium-ion (Li-ion) battery cells.
HV Battery Assembly
• The HV battery assembly is enclosed in a metal case and is rigidly mounted
in the lower part of the cargo area behind the rear seat. The metal case is
isolated from high voltage and concealed by a carpeted panel in the cabin
area.
• The HV battery assembly consists of 3.7 Volt Li-ion battery cells connected
in series-parallel circuit to produce approximately 207.2 Volts. Each Li-ion
battery cell is non-spillable and contained in a sealed metal case.
• The electrolyte used in the Li-ion battery cells is a flammable organic
electrolyte. The electrolyte is absorbed into the battery cell separator and
will not normally leak, even in a collision.
