  • Publication number: 20220219673
    Abstract: A control system for a hybrid vehicle that is configured to generate a driving force as required even if it is necessary to charge a battery rapidly. The hybrid vehicle may be propelled in a parallel mode in which power of the engine is partially translated into electric power by a motor and the remaining power of the engine is delivered to drive wheels. In a case that a rapid charging command is transmitted and that a required driving force is greater than a first driving force, the motor is operated to generate electric power in a predetermined amount, and the driving force is restricted to the first driving force.

  • Publication number: 20160133941
    Abstract: The invention provides an anode capable of improving battery characteristics such as cycle characteristics and a battery using it. An anode current collector is provided with an anode active material layer. The anode active material layer contains at least one from the group consisting of simple substances, alloys, and compounds of silicon or the like capable of forming an alloy with Li. Further, the anode active material layer is formed by vapor-phase deposition method or the like, and is alloyed with the anode current collector. Further, Li of from 0.5% to 40% of an anode capacity is previously inserted in the anode active material layer. Therefore, when Li is consumed due to reaction with an electrolyte or the like, Li can be refilled, and potential raise of the anode can be inhibited in the final stage of discharge.

  • Patent number: 8216724
    Abstract: A polymer electrolyte capable of obtaining superior discharge characteristics and a battery using it are provided. A cathode (21) and an anode (22) are wound with a separator (24) in between. After that, the wound body is contained inside a package member. Then, an electrolytic composition containing a solvent, polyvinyl acetal or the derivative thereof, and lithium hexafluorophosphate is added thereto. Polyvinyl acetal or the derivative thereof is polymerized by using lithium hexafluorophosphate as a catalyst. Thereby, a polymer electrolyte (23) is formed, and the discharge characteristics are improved.
