Publication number: 20150329007Abstract: A power supply control device includes: a generator driven by an engine; a lead acid battery and a lithium ion battery connected in parallel to the generator; an SOC detector that detects SOC of the lead acid battery; and a charge controller that controls charging of the lead acid battery. The charge controller performs the charge control based on a regenerative predictive amount estimated according to vehicle state information when the SOC is greater than a threshold SL1. The charge controller performs the charge control irrespective of the regenerative predictive amount when the SOC is less than SL1. When the surplus of charge of the lithium ion battery is larger than a deficient of charge of the lead acid battery, the charge controller performs the charge control based on the regenerative predictive amount, regardless of the SOC being less than SL1.Type: ApplicationFiled: May 12, 2015Publication date: November 19, 2015Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masaki MATSUNAGA, Kazuhito ESHIMA, Takeaki SUZUKI
