Provided is a secondary battery system which can accurately detect a state of a secondary battery system (such as a secondary battery state and a secondary battery system failure). The secondary battery system (6) includes dV/dQ calculation means which calculates a dV/dQ value as a ratio of a change amount dV of a battery voltage V of a secondary battery (100) against a change amount dQ of an accumulation amount Q when the accumulation amount Q of the secondary battery (100) is changed. The secondary battery system (6) detects the state of the secondary battery system (6) by using the dV/dQ value.

A power supply device for a vehicle includes a battery (B1) which serves as a first power storage device, a battery (B2) which serves as a second power storage device, a vehicle load, a selection switch (RY0) which selects one of the first and second power storage devices and connects the selected power storage device to the vehicle load, and a control device (60) which, when a current flowing through the selection switch (RY0) is larger than a prescribed value, controls the vehicle load so that the current flowing through the selection switch (RY0) is made smaller than the prescribed value, and switches the selection switch. Preferably, when the control device (60) switches the selection switch (RY0), the control device controls inverters (20, 30) to achieve a balance between electric power generated in a first motor generator (MG2) and electric power consumed in a second motor generator (MG1).

A vehicle comprises a battery, i.e. a power storage unit having a capacity different from a reference capacity, a current sensor for detecting a current inputted to the power storage unit or outputted therefrom and delivering the detection value by converting it depending on the ratio of the capacity of the power storage unit to the reference capacity, and a controller performing current integration by receiving the output from the current detecting section and judging charged state of the power storage unit. The current sensor preferably comprises a sensor for measuring a current flowing through wiring connected with the power storage unit, and a converting section for converting the sensor output depending on the ratio of the capacity of the power storage unit to the reference capacity. When the capacity of the power storage unit is equal to n times of the reference capacity, the converting section delivers the sensor output while multiplying by 1/n.

To provide an electrode for secondary battery, electrode which can materialize secondary batteries that are adapted into producing high output and additionally whose durability is high.It is characterized in possessing an electrode material that has an active-material powder 11, a conductive material 12 being formed of a carbonaceous material, and being adhered to a surface of said active-material powder 11, and fibrous conductive materials 13 being bonded to said conductive material 12. First of all, it becomes feasible to maintain the electric connection between the active-material powder and the conductive material stably by adhering the conductive material to a surface of the active-material powder. Further, the fibrous conductive materials are bonded to the conductive material that is adhered to a surface of the active-material powder. It is feasible to maintain the electric connection by getting the fibrous conductive materials entangled to each other. That is, it is feasible to keep the electric connection even when strains occur in the electrode material, because the fibrous conductive materials absorb the strains to keep the mutual contacts; even if large strains occur, it is possible to maintain the electric connection, because it is not disconnected compared with that in conventional conductive materials.
摘要:
A request determining unit compares a battery temperature of a battery unit with a predetermined temperature management value, and produces a heating request or a cooling request when a temperature deviation of a predetermined threshold is present between them. A current direction determining unit determines, based on thermal reaction characteristics of the battery unit, in which one of a direction on a charge side and a direction on a discharge side a current is to be passed for responding to the heating request or the cooling request. A target current value determining unit determines a target current value related to the charge/discharge determined by the current direction determining unit. A current control unit produces a switching instruction for matching a battery current of the battery unit with the target current value provided from a selecting unit.
