Embodiment Construction
[0019] One or more specific embodiments of the technology are described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described in the specification. It should be understood that during the development of any such actual implementation, for example, in any engineering or design project, many implementation-specific decisions must be made in order to achieve the developer's specific goals, for example, compliance with system-related and business-related constraints, which may vary between implementations. In addition, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and production for one of ordinary skill having the benefit of this disclosure.
[0020] As noted above, vehicle technology has improved to increase fuel economy and / or reduce undesirable emissions compared to more tradition...

A micro-hybrid battery system (12) includes a lithium-ion battery module (28) configured to couple with an electrical load. The lithium-ion battery module (28) includes a housing. The lithium-ion battery module (28) also includes a first lithium-ion battery cell (44a), the first lithium-ion battery cell is arranged in the housing, and has a first active material chemical composition, the first active The material chemical composition includes a first cathode active material and a first anode active material. The lithium-ion battery module (28) also includes a second lithium-ion battery cell (44b), the second lithium-ion battery cell is electrically connected to the first lithium-ion battery cell (44a), and is arranged on inside the housing. The second lithium-ion battery cell (44b) has a second active material chemical composition comprising a second cathode active material and a second anode active material. The first and second active materials are chemically different, and thus the first and second lithium-ion battery cells (44a, 44b) have different open circuit voltages.
