A battery system includes a lithium ion battery that couples to an electrical system. The battery system also includes a battery management system that electrically couples to the lithium ion battery and controls one or more recharge parameters of the lithium ion battery. Additionally, the battery management system monitors one or more parameters of the lithium ion battery.

Cooling strategy for battery systems

A module-based framework evaluates designs of advanced start stop systems, particularly 12 V advanced start stop systems. The framework separates vehicle and battery analysis and uses a power profile to evaluate different designs of the vehicles and batteries. Particularly, the framework can evaluate different battery solutions and compare performances as a function of drive cycles, motor size, and electrical loads. In addition to modeling, actual batteries are tested for the same power inputs for validating performance differences. This framework identifies performance limiting components for determination of the vehicle system component optimization.

A battery system may include multiple battery cells having different chemistries. To achieve certain performance goals, voltage parameters for the battery system, such as cruising voltages and maximum voltages can be adjusted. These adjustments may, for example, direct charging currents to a lithium-ion battery to increase fuel economy or may direct charging currents away from a lithium-ion battery to increase its longevity. Methods for matching batteries having different chemistries based on their open circuit voltages are also discussed.
