Abstract: PROBLEM TO BE SOLVED: To provide a residual capacity detecting device which can warn the decline of the residual capacity of a battery at appropriate timing and, at the same time, can prevent the shortening of the service life of the battery by preventing the overdischarge of the battery by detecting the opened terminal voltage of the battery and comparing residual capacity values of the battery found by different methods when a motor is not driven and the charging and discharge currents of the battery are zero. SOLUTION: A microcomputer 4 starts to estimate the residual capacity of a battery 1 when the computer confirms the stoppage of a motor 10 from the computed results of a controller 12 on the actual load torque of the motor 10 and the rotating speed of the motor 10 and recognizes that the discharge current of a battery 1 is zero at the moment when the actually measured current value becomes zero. The computer 4 detects the fluctuating range of the terminal voltage of the battery 1 at every unit time and finds an estimated residual capacity value from a plurality of terminal voltage-residual capacity characteristic maps prepared in advance correspondingly to the temperature of the battery 1 by regarding that the terminal voltage of the battery 1 is stabilized at the moment the computer 4 detects that the fluctuating width is zero.  Finally, the computer 4 corrects a theoretical residual capacity value from the cumulative computation of actually measured charging and discharge currents by using the estimated residual capacity value.

Filed: 1981-11-27
Abstract: PURPOSE:To obtain a molding with a better appearance preventing expansion of an FRP base plate during heating by hardening the base plate by heat with both sides thereof grasped with a pair of perforated plate bodies prior to the press molding. CONSTITUTION:An FRP blank plate 1 is transferred in a heating furnace 3 grasped with two opposed endless perforated plate-shaped bodies 5 and 5' with a surface opening rate of more than 60% having numerous holes ranging 1-10mm. in the diameter and softened by heat from above and below with infrared heating elements 4 provided therein 3.
