Definitions

  • This invention relates to switching apparatus.
  • This invention has particular but not exclusive application to automotive electrical systems, and for illustrative purposes reference will be made to such application. However, it is to be understood that this invention could be used in other applications, such as stationary battery-powered equipment.
  • Modern motor vehicles contain many accessories which are operated by the vehicle electrical system. When the engine is running, these accessories are powered by the engine- driven alternator. When the vehicle is stationary, some accessories such as lights, fans and audio systems may still be operable, drawing power from the vehicle battery. On occasions, the power drawn from the battery while the engine is not operating may discharge it to the extent that it cannot start the engine. If this occurs, the vehicle must be push or jump-started before the battery can be recharged by the alternator, and this can be very inconvenient.
  • the present invention aims to alleviate the above disadvantage and to provide switching apparatus which will be reliable and efficient in use. Other objects and advantages of this invention will hereinafter become apparent.
  • this invention in one aspect resides broadly in switching apparatus for regulating the output from an energy storage apparatus, including:- regulating apparatus for regulating the output from said energy storage apparatus; monitoring apparatus for monitoring a measure of the state of charge of said energy storage apparatus, and control means responsive to said monitoring apparatus for controlling said regulating apparatus for selectively switching said output according to said state of charge.

It is preferred however that the regulating apparatus be formed to interrupt the flow of power until the override switch is operated, such that an operator may be made aware of the operation of the switching apparatus.
  • Override alarm means such as a warning light, may be associated with the override switch for indicating operative use thereof whereby a user may be made aware that the switching apparatus is not functional.

  • the output of the comparator will remain high, energising the relay coil 12 and holding the relay contact 13 closed such that the accessories 30 and 31 may be energised. If the accessories 30 and 31 draw current while the battery 28 is not being charged and the battery voltage drops to a pre-determined level, the voltage appearing at the inverting input 17 will fall below the constant voltage on the non-inverting input 25, sending the output of the comparator 15 low and de-energising the relay coil 12. This opens the relay contact 13, disconnecting the accessories 30 and 31 from the battery 28 and preserving its remaining charge for starting the vehicle.
  • the monitoring assembly 14 is also disconnected from the battery 28 by the opening of the relay contact 13 such that any momentary increase in battery voltage due to a reduction in loading does not cause the comparator output to be sent high again, as this would allow the relay contact 13 to reconnect the accessories 30 and 31.

On receipt of such a code number, the decoder 64 energises the solenoid 66, permitting the bonnet 70 to be opened for access to the engine compartment and also energises the security relay coil 65, permitting the engine to be started.

Abstract

L'appareil de commutation décrit, qui est destiné à être utilisé notamment dans une automobile, sert à déconnecter sélectivement des charges électriques (30 et 31) d'un accumulateur électrique (28) au moyen d'un relais (12), lorsque la tension de sortie de l'accumulateur électrique (28) tombe au-dessous d'une valeur minimale pré-établie. Un commutateur de dérivation (32) est également prévu pour reconnecter les charges électriques essentielles, telles que les circuits de mise en marche et d'allumage du véhicule. L'appareil de commutation peut être exploité en conjonction avec un appareil de sécurité qui utilise le relais (12) pour connecter l'accumulateur électrique (28) aux charges (30 et 31), uniquement après introduction d'un code d'entrée prédéterminé au moyen d'un clavier (63). Le décodeur (64) pour le clavier (63) et l'accumulateur électrique (28) sont placés à l'intérieur du compartiment moteur et sont protégés contre les interférences par un attache-capot libéré par solénoïde (67).
