Examples: Hybrid High Voltage Levels

The design voltage used in hybrids varies substantially. For safety, the industry has adopted a convention of using orange insulation on high voltage wiring to facilitate identification. Here are a few examples of voltage in hybrid systems.

Vehicle Battery Voltage Maximum Voltage (from Inverter/Converter) Identification
Honda Civic and Insight [1] 144 (120 1.2V cells) N/A "Hybrid" on rear
Toyota Prius [2,3] 201 (28 7.2 V cells) 500 "Hybrid Synergy Drive" on rear
Lexus [4] 288 (30 9.6V cells) 650 "400h" on body
Gillig Hybrid Bus [5] N/A 900
