Embodiment Construction

[0020] One or more specific embodiments 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 appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developer's specific goals, for example, compliance with system-related and business-related Constraints, which may be different in different implementations. Furthermore, it should be understood that such a development effort might be complex and time consuming, but would nonetheless be a routine undertaking of design, construction, and manufacture for one of ordinary skill having the benefit of this disclosure.

[0021] As discussed above, dual-battery xEV vehicle systems may offer numerous advantages over traditional gas-powered vehicle technology. Furthermore, dual-battery...

Abstract

The present disclosure includes an automotive battery system including a first battery that couples to an electrical system. Additionally, the first battery includes a first battery chemistry. Further, the automotive battery system includes a second battery coupled in parallel with the first battery and couples to the electrical system. Furthermore, the automotive battery system includes a first switch coupled to a positive terminal of the second battery, which electrically couples or decouples the second battery to or from the electrical system. Moreover, the automotive battery system includes a battery control unit that detects a short circuit condition of the first battery, the second battery, or both and decouples the second battery from the electrical system by opening the first switch upon detecting the short circuit condition.

Description

Background technique [0001] The present disclosure relates generally to the field of batteries and battery modules. More specifically, the present disclosure relates to high voltage battery connectors that may be used in vehicular situations as well as other energy storage / dissipation applications. [0002] This chapter hopes to introduce the reader to various aspects of technology that may be related to aspects of the disclosure described below. This discussion is considered helpful in providing the reader with background information in order to better understand aspects of the disclosure. Accordingly, it should be understood that these statements are to be read in this light and not as admissions of prior art. [0003] Vehicles that use one or more battery systems to provide all or a portion of the vehicle's power may be referred to as xEVs, where the term "xEV" is defined herein to include all vehicles, or any variation or combination thereof, that use electric power to ...
