Abstract
A charging method for a plurality of squibs which charges up each storage device built in or attached to each squib which is connected to an ignition control device via a common bus, and can be selectively operated by electrical energy and electrical signals which are supplied from the ignition control device, in which, in the case of charging each storage device, the ignition control device carries out a direction of charging initiation, an electric power supply for charging, and a direction of charging stop for each storage device successively, thereby the charging for all storage devices is completed.
Claims16
A method for charging any multiple number of squibs connected to a common bus, each squib including a storage device and being connected to a common ignition control device via the bus, and wherein each squib is selectively operated by electrical energy and electrical signals from the ignition control device, the method comprising the steps of:
- operating the ignition control device to carry out a direction of charging initiation, an electric power supply for charging, and a direction of charging stop for each storage device successively until the charging for all storage devices is completed;
- wherein each squib further includes an initial charging circuit and a stationary charging circuit connected to the bus via a switch which is switched by a signal from the ignition control device;
- and determining a charged condition of the storage device of each squib solely based on current level in said bus.
A charging method for any multiple number of squibs, each including a storage device and connected to a common ignition control device via a common bus, and wherein each squib is selectively operated by electrical energy and electrical signals from the ignition control device, wherein the method comprises the steps of:
- operating the ignition control device to charge the charge storage device of one said squib by carrying out a direction of charging initiation, an electric power supply for charging, and a direction of charging stop;
- and
- thereafter successively repeating said charging step for each of the charge storage devices of each of the remaining squibs until the charging for all storage devices is completed;
- wherein each squib further includes an initial charging circuit and a stationary charging circuit connected to the bus via a switch which is switched by a signal from the ignition control device;
- and
- determining a charged condition of the storage device of each squib solely based on current level in said bus.
