The fourth mode (Electric Only Combined Engine On) is a series-parallel mode. The 2nd generation Volt's 5ET50 transaxle has 5 modes of operation. Two modes are electric only, one mode is a series-hybrid mode, and the Two remaining modes (series-parallel) allow the ICE to contribute torque to the wheels through the planet carrier of the input gear set. This transaxle is used in a Malibu Hybrid with only 4 modes (they removed the series mode). **1st generation Volt battery. If an individual cell is rated at 55.5Wh (using units of measure) Power (Wh) = EMF (V) x Current (A), then the current rating would be Wh/V = Ah. So 55.5Wh/3.7V = 15 Ah rather than the 55.5 Ah I mistakenly said/displayed in the video. This is the first is a series of videos on the 2 generations of the Chevrolet Volt. This episode covers the removal and detailed reassembly of the 355.2-Volt battery and battery relay assembly from a 2018 Chevrolet Volt. The 2016-2018 Chevrolet Volt batteries are the same. The 2011-2015 Chevrolet Volt battery is similar but has some minor differences. ABOUT US Weber State University (WSU) Davis Campus - Automotive Technology Department - Advanced Vehicles Lab.
