There are Multiple Types of Hybrids
Micro HEV (a.k.a Stop/Start)

Low voltage

Shuts down engine at idle to save fuel

Example: BMW 1,3 mini series – JCI is the world leader
in AGM micro hybrid batteries
Mild HEV

Low to medium voltage

Includes stop-start, regeneration braking and acceleration
assist

Example: Saturn Vue, S-class, 7-series
Full HEV

High voltage

There are Multiple Types of Hybrids
Plug-In Hybrid (PHEV)

High voltage
Includes all full hybrid features PLUS
electric-only operation for ~20 miles
Ability to recharge battery through 120V electrical outlet

Energy of Battery Systems is strongly related to the chemical Energy
The laws of nature have fixed limits to specific energy of electrochemical systems
from the periodic table of elements
Li-Ion battery technology offers low weight, high reduction potential chemistry.
- High voltage due to high chemical energy:
- Low weight of Lithium metal
- High mobility of Li-Ions in solid state materials
