Patent number: 9463709Abstract: A vehicle includes a controller. When a brake operation amount has increased, the controller calculates an estimated input value at the time when a main battery is charged in response to an increase in the brake operation amount, on the basis of a current speed and an amount of increase in brake operation amount. The controller discharges the main battery for charging an auxiliary battery at a current value that is calculated on the basis of the estimated input value by controlling an operation of a DC-DC converter before charging the main battery in response to an increase in the brake operation amount. Thus, it is possible to cancel a bias of salt concentration that is developed during charging by a bias of salt concentration that is developed during discharging, so, after the main battery has been charged, it is possible to suppress development of a bias of the salt concentration and suppress an increase in the internal resistance value of the main battery.Type: GrantFiled: July 22, 2015Date of Patent: October 11, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kazuhisa Takeda, Hiroki Tashiro, Hideaki Oka, Shuji Tomura

Publication number: 20150111098Abstract: The present invention provides a method of safely producing a solution containing a tetrafluoro(oxalate)phosphate in which the amounts of chlorine compounds and free acids are low such that crystallization refinement is not required in a post-process. The method produces a tetrafluoro(oxalate)phosphate solution by mixing a tetrafluoro(oxalate)phosphate with oxalic acid in a non-aqueous solvent and then adding silicon tetrachloride to the resulting mixture solution for reaction. In the reaction, the addition ratio of the hexafluorophosphate, oxalic acid, and silicon tetrachloride is controlled such that the amount of the hexafluorophosphate is 1.90 moles or more and the amount of the oxalic acid is 1.90 to 2.10 moles, based on 1 mole of the silicon tetrachloride.Type: ApplicationFiled: May 29, 2013Publication date: April 23, 2015Inventors: Makoto Kubo, Takayoshi Morinaka, Keita Nakahara, Satoshi Muramoto
