摘要： An ECU determines whether the ripple current is within a target range (S50). When it is determined that the ripple current is not within the target range (NO in S50), the ECU determines whether the ripple current is greater than or less than the target range (S80). When it is determined that the ripple current is less than the target range (NO in S80), the ECU reduces the carrier frequency of the boost converter that is a component of the ripple generating section (S90). On the other hand, when it is determined that the ripple current is greater than the target range (YES in S80), the ECU increases the carrier frequency of the boost converter (S100).

摘要： A battery model unit includes an electrode reaction model unit based on the Butler_Volmer equation, an electrolyte lithium concentration distribution model unit analyzing a lithium ion concentration distribution in an electrolyte solution by a diffusion equation, an active material lithium concentration distribution model unit analyzing an ion concentration distribution in a solid state of an active material by a diffusion equation, a current/potential distribution model unit for obtaining a potential distribution according to the charge conservation law, a thermal diffusion model unit and a boundary condition setting unit. The boundary condition setting unit (66) sets a boundary condition at an electrode interface such that a reacting weight at the electrode interface is not determined by a difference in material concentration between positions but a deviation from an electrochemically balanced state causes a change with time in lithium concentration at the interface and thus a (time-based) drive power for material transportation. Thereby, an appropriate charge/discharge control can be performed based on the battery model having the appropriately set battery condition.

摘要： A battery state estimating unit (110) estimates an internal state of a secondary battery according to a battery model equation in every arithmetic cycle, and calculates an SOC based on a result of the estimation. A parameter characteristic map (120) stores a characteristic map based on a result of actual measurement performed in an initial state (in a new state) on a parameter diffusion coefficient (Ds) and a DC resistance (Ra) in the battery model equation. The parameter change rate estimating unit (130) estimates a DC resistance change rate (gr) represented by a ratio of a present DC resistance (Rc) with respect to a new-state parameter value (Ran) by parameter identification based on the battery model equation, using battery data (Tb, Vb and Ib) measured by sensors as well as the new-state parameter value (Ran) of the DC resistance corresponding to the p resent battery state and read from the parameter characteristic map (120).
