Definitions
- the invention relates to a safety switch for preventing unintentional vehicle battery discharge, for example by external electrical consumers, which are connected to a vehicle socket, such as the socket for the cigarette lighter.
- US-A-3 395 288 proposes the use of a Zener diode as a switch. However, because of their high power consumption, Zener diodes are also unsuitable for such safety switches.
- the invention has for its object to provide an improved safety switch to prevent accidental battery discharge. This object is achieved with the features of the claims.
- the invention is based on the basic idea of using a semiconductor switch as a safety switch which, for example, depending on the elapsed time after the ignition has been switched off or on the current state of charge of the battery, disconnects the vehicle sockets from the vehicle battery.
- the use of a semiconductor switch is associated with the particular advantage that the semiconductor safety switch according to the invention does not require any quiescent current due to its powerless activation even when it is switched on.
- Another advantage of the safety switch according to the invention is that the preparation of the relay, which is necessary, for example, for Australia can be omitted in all vehicles. The requirement existing in Australia to disconnect the socket for the cigarette lighter from the power supply via the ignition is then met when using the safety switch according to the invention by programming the electronic control device controlling the safety switch during or after production of the vehicle.
- the semiconductor safety switch according to the invention is individually programmed for the corresponding The control unit of the vehicle is set to a permanent voltage supply even after the ignition has been switched off (for example for connecting a refrigerator for medication).
- the preferred embodiment of the responsibility for monitoring the battery status passes to the driver, this rare individual need can be solved with one and the same Safety switches are met, which prevents accidental discharge of the battery in conventional use according to the invention.
- the use of the semiconductor safety switch according to the invention is associated with the advantage that the same hardware is suitable and adaptable for different needs and such special cases are not already in use Production of the vehicle must be taken into account (for example by installing other hardware components), but also subsequently by reprogramming the control unit for the semiconductor Sic safety switch can be satisfied
- the semiconductor safety switch according to the invention is used to monitor the fault of the vehicle socket.
- the current draw via the semiconductor is monitored via the semiconductor, for example by means of a SenseFET semiconductor.
- the current draw is either too high if, for example, the refrigerator is too large Vehicle socket is connected, or if power is drawn for too long, the semiconductor is controlled accordingly and thus the power supply to the socket is interrupted.
- the safety switch according to the invention serves to charge the battery of the vehicle, for example via the cigarette lighter, or to maintain the existing charge.
- a semiconductor switch is used which works with reverse polarity with little polarity reversal.
- This possibility of external charging of the vehicle battery is, for example In showrooms or at auto shows, this is an advantage if electrical consumers are permanently in operation for a long time (e.g. lighting) or are constantly operated by the public (e.g. power windows, electric seat adjustment, etc.)
- Semiconductor safety switches allow recharging or trickle charging of the battery in a simple and discreet manner, without a charger having to be connected directly to the terminals of the vehicle battery.
- Conventional safety switches do not allow such bidirectional current flow (ie current consumption by connected consumers, on the one hand, and charging current, on the other hand).
- the charging function is activated from the outside via a serial interface of the vehicle, the so-called diagnostic connector the electronic control device controlling the semiconductor switch is reprogrammed accordingly or the "charging" function is activated.
- there is automatic detection If, for example, there is a voltage at the output of the semiconductor safety switch or the battery that exceeds a predetermined threshold value, the safety switch switches through and allows a current to flow in the opposite direction and thus to charge the battery.
- the charging function is activated via an additional switch.
- various alternatives are also provided for ending the “charging” state.
- Switching according to a first alternative takes place when a certain voltage threshold at the output of the switch or the battery is undershot again.
- the switching takes place when a certain state of charge is undershot (ie the charger has been removed) or exceeded (ie the battery is full).
- switching takes place after a predetermined period of time.
- the additional switch is again in the “OFF” position brought. Finally, there is a switchover if no charging current is detected in the battery.

Abstract
L'invention concerne un commutateur de sécurité servant à éviter que la batterie d'un véhicule ne se décharge involontairement, par exemple à cause de consommateurs électriques externes reliés à une prise de courant dans le véhicule, tels que la prise de l'allume-cigares. Selon l'invention, un commutateur statique est utilisé comme commutateur de sécurité, ce commutateur séparant les prises de courant du véhicule de la batterie, par exemple, en fonction du temps écoulé après arrêt de l'allumage ou bien en fonction de l'état de charge momentané de la batterie.
