摘要： PROBLEM TO BE SOLVED: To accurately detect an inflammable gas concentration without being affected by miscellaneous gas existing in a measuring atmosphere, and to provide high detection precision. SOLUTION: This gas detector is a detector for detecting an inflammable gas concentration generated in a measured chamber A, a residual oxygen concentration inside the measured chamber A is measured by the first oxygen sensor part 2 of a limiting current type having a pair of electrodes 22, 23 in both faces of a zirconia substrate 21 of an oxide ion conductive solid electrolyte, after the inflammable gas generated reacts with oxygen in atmospheric gas, and an oxygen concentration in an outside space D where the atmospheric gas introduced into the chamber A exists is measured, on the other hand, by the second oxygen sensor part 3 of a limiting current type having a pair of electrodes 32, 33 in both faces of a zirconia substrate 31. Since gas components.concentrations excepting the inflammable gas are the same in the gas in the chamber A and the gas in the space D, influences caused by the miscellaneous gas components such as a steam containned in the atmospheric gas are corrected based on a detection result by the second oxygen sensor part 3 so as to accurately detect the inflammable gas concentration.

摘要： PROBLEM TO BE SOLVED: To more accurately detect the charged state (SOC) of a battery. SOLUTION: A battery ECU 14 detects the SOC of a battery 10 based on the voltage V detected by means of a voltage detector 12 and the current I detected by means of a current detector 18. At the time of detecting the SOC, SOC is determined whether 80% or 20% when the electromotive voltage V0 obtained by subtracting the internal voltage drop of the battery 10 caused by the internal resistance R of the battery 10 from the voltage V becomes higher or lower than a prescribed value, but the polarization electromotive voltage Vdyn based on the polarization of a battery cell contained in the electromotive voltage V0 is taken into consideration.

摘要： PROBLEM TO BE SOLVED: To detect the concentration of a flammable gas without being affected by the influence of moisture or the like with a simple configuration by using an oxygen sensor with a solid electrolyte material, for example, of a limiting current type. SOLUTION: A first oxygen sensor 3A is provided at the downstream side of a generation source 2 of a channel 1 where air is circulated through the generation source 2 of a flammable gas for detecting oxygen concentration being shifted by the amount of oxygen consumption due to the flammable gas of circulation air containing the flammable gas, a second oxygen sensor 3B is provided at the upstream side of the generation source 2 for detecting the oxygen concentration of the circulation air without containing the flammable gas, and a gas concentration output means 4 outputs the difference in the detection signal of both the oxygen sensors 3A and 3B as the concentration of the flammable gas of air through the generation source 2, thus canceling the amount of change in the detection signal of the oxygen sensors 3A and 3B due to the fluctuation of moisture or the like and hence preventing the concentration of the flammable gas to be detected from being affected by moisture or the like.

摘要： PROBLEM TO BE SOLVED: To suppress the arrival of a battery storage amount at a lower limit in a hybrid vehicle.
SOLUTION: An error of a current measuring system having a current sensor 15 is previously evaluated, and set to a battery ECU 14. The battery ECU 14 offsets an integrated current in the case of estimating a battery charge storage amount by integrating the current measured by the sensor 15 to a discharge side by an error amount of the measuring system. Since the battery ECU 14 controls to charge or discharge so as to hold the estimated charge storage amount constant, in the case of offsetting to the discharge side, a control is operated to supplement it, and hence charging becomes superior to the case of conducting no offset. Thus, the arrival of the real battery charge storage amount at a lower limit of the battery charge storage amount is suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of an alkaline storage battery that can reduce the period from manufacturing to delivery. SOLUTION: An electrode is manufactured by fixing an active material and a conductive auxiliary agent such as graphite on an electrode board by the use of a binder formed of a non-conductive material such as PTFE. The electrode is immersed in a KOH solution that is an electrolyte used for an alkaline storage battery and an ultrasonic treatment is applied to it. The alkaline storage battery is assembled by using a ultrasonic treated electrode The alkaline storage battery thus obtained can provide a predetermined capacity and output from the beginning and does not cause a trouble such as a short circuit, so that it can be shipped immediately after the assembly.

摘要： PROBLEM TO BE SOLVED: To perform charging when an overdischarge cell is generated. SOLUTION: A voltage detector 12 detects a voltage of a battery block of an assembly battery 10. When voltage difference between the respective battery blocks has become equal to or higher than a specified value (e.g. 1V), existence of an overdischarge cell is detected. In this case, a battery ECU 14 sets the SOC(state of charge) of the assembly battery 10 to a control lower limit value (e.g. 20%). Thereby an HVECU 16 controls a load 18 to place the assembly battery 10 in a chargeable state. In the case when discharge is generated, the assembly battery 10 is cut off from the load 18 by a relay 20.

摘要： PROBLEM TO BE SOLVED: To conduct discharging control which satisfies the charging condition of a battery. SOLUTION: Voltages of respective battery blocks 50-1 to 50-n of a battery 50 are detected respectively by voltage sensors 70-1 to 70-n. A discriminating part 82 groups the battery blocks 50-1 to 50-n with the ones, the temperature of which are comparatively approximate to each other collected, and calculates the maximum voltage difference between the blocks in respective groups. A maximum value MAX(ΔVn) in a maximum voltage difference between the respective groups is taken out, which is compared with a first threshold. When it is equal to the first threshold or higher, the discharging amount of the battery 50 is restricted. When the MAX(ΔVn) turns into the second threshold or higher, the discharging of the battery 50 is stopped.
