Patent number: 4287465Abstract: An aleatory source of energy, e.g., a battery of photocells (1), supplies energy to a load (5) and to a storage battery (3). When the source is supplying more energy than is being drawn by the load, the storage battery is charged; when the source is supplying less than the demand, the shortfall is made up by drawing energy from the storage battery. The state of charge of the storage battery is monitored by a meter (8) which governs a regulator (7). Once the battery is charged to a predetermined threshold, the amount of current it draws from the source is regulated, and energy supplied by the source in excess of the combined requirements of the load and of battery charging is diverted to a storage means (6) other than the storage battery (e.g., a mains electricity supply grid). The flows of energy to both the battery and the other storage means are controlled by the regulator (7) as a function of the state of charge of the battery.Type: GrantFiled: October 5, 1979Date of Patent: September 1, 1981Assignee: Saft-Societe des Accumulateurs Fixes et de TractionInventors: Pierre Godard, Michel Billot

Patent number: 4232305Abstract: The invention relates to electronic warning devices. The control system includes means for supplying an accurate clock signal and a divider (CD1, CD2) for dividing the clock signal to obtain an audio frequency, adjusting the mark/space ratio of the audio frequency for application to a power transistor (T6), said transistor driving a loudspeaker (HP), providing a cyclic modulation for modulating the clock frequency; and timing the duration of the sound emission of the loud speaker. The timing functions can all be provided without the use of electrolytic capacitors as would otherwise have been necessary, thereby avoiding problems due to the lack of precision and drift in the values of such capacitors.Type: GrantFiled: December 18, 1978Date of Patent: November 4, 1980Assignee: Saft-Societe des Accumulateurs Fixes et de TractionInventors: Daniel Lelaidier, Pierre Godard

Patent number: 4210854Abstract: A method of charging a secondary electric battery from a primary source of electric current, the secondary battery being connected to supply an intermittent load that draws a current which is greater than the primary source is capable of supplying the method comprising recording the quantity of electricity discharged by the secondary cell, charging the secondary battery at a first rate from the beginning of its discharge, and continuing the charging at the said first rate for a period of time which is a function of the recorded discharge.Type: GrantFiled: March 22, 1978Date of Patent: July 1, 1980Assignee: Saft-Societe des Accumulateurs Fixes et de TractionInventor: Pierre Godard

Patent number: 4125802Abstract: Method and apparatus for charging storage batteries in which the charging rate is varied as a function of temperature are disclosed. The battery temperature and ambient temperature are sensed and compared. When the battery temperature is less than the ambient temperature plus a first temperature difference, a first charging rate is provided; when the battery temperature is greater than the ambient temperature plus the first temperature difference but less than the ambient temperature plus a second temperature difference which is greater than the first temperature difference, an intermediate charging rate is provided which varies with the comparison of the battery and ambient temperatures between the first charging rate and a second charging rate which is less than the first charging rate; and when the battery temperature is greater than the ambient temperature plus the second temperature difference, the second charging voltage is provided.Type: GrantFiled: September 21, 1976Date of Patent: November 14, 1978Assignee: Saft-Societe des Accumulateurs Fixes et de TractionInventor: Pierre Godard

Patent number: 4065712Abstract: A system and method for effecting rapid safe charging of sealed storage cells embodying a charger to supplying a rapid high rate charging current to the cells or battery of cells with interruption but once during charging, at an optimum time to prevent cell or battery damage, the timing of this interruption being effected by change in magnitude of a continuous control signal by means incorporated in the cell or battery. This magnitude changes when voltage across the cell terminals increases above a reference voltage that varies with change in battery or cell temperature, the change in said magnitude of the control signal serving to effect interruption of rapid charging. Subsequent to this interruption charging at a slower rate proceeds to complete the charge of the sealed cell or battery of such cells.Type: GrantFiled: February 1, 1974Date of Patent: December 27, 1977Assignee: Societe des Accumulateurs Fixes et de TractionInventors: Pierre Godard, Robert Henri Lapuyade
