The auxiliary battery has a predetermined operating range of charge levels. The auxiliary battery is charged to an upper charge level using an external power source thereby reducing energy used from the onboard charging system to charge the auxiliary battery during a drive mode of the vehicle. The upper charge level may be substantially similar to an upper level of the predetermined operating range of charge levels or greater than the predetermined operating range of charge levels. The auxiliary battery may be allowed to discharge to a lower charge level, which may be substantially similar to a lower level of the predetermined operating range of charge levels or less than the predetermined operating range of charge levels."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for charging an auxilary battery in a plug-in electric vehicle","description":"A system and method is provided for charging an auxiliary battery in a plug-in electric vehicle with an onboard charging system.
