DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to an electric source control device of an internal combustion engine drive vehicle provided with a primary battery and a secondary battery which are charged in parallel by a generator.
BACKGROUND TECHNOLOGY
Generally speaking, the excessive discharge of a battery of an internal combustion engine drive vehicle such as an automobile often causes the impossibility of starting resulting from the lack of the electricity remaining in the battery and hence the lack of the power for starting an engine starter. A reason why such an accident occurs is that a driver drives the vehicle for a long time without exchanging the battery, but a stronger reason is that a driver uses a room air-conditioner and lights in the vehicle during stopping because of a traffic jam at night which is one of recent traffic problems.
A conventional method for resolving such a problem is to use a spare battery by manual operation, but there is a problem in the method that it is necessary to charge the battery supplementarily by manual operation according to circumstance as a matter of course.
Thus the purpose of the present invention is to supply people with an electric source control device of an internal combustion engine drive vehicle provided with a primary battery and a secondary battery kept in a state in which they are always charged to make it unnecessary to change the battery manually when it is almost discharged.
DISCLOSURE OF THE INVENTION
An electric source control device of an internal combustion engine drive vehicle according to the present invention is characterized in that it consists of combustion engine drive vehicle, which are provided with a common terminal of (+) polarity and two independent terminals of (-) polarity and which are used to supply an engine starter and loads with electricity, battery in parallel and which is driven by an engine mounted on said internal combustion engine drive vehicle, (-) polarity of said primary battery with the terminal of (-) polarity of said secondary battery and to disconnect the former from the latter, terminals of (-) polarity of said primary battery and said secondary battery alternately with minus terminals of said engine starter and said loads, battery and said secondary battery with said engine starter when an engine switch is connected with a starting point, and the starting point said primary control contact point moves to its OFF position to disconnect the terminals of (-) polarity of said primary battery from that of said secondary battery, terminal of (-) polarity of said primary battery and that of said secondary battery to make only one of said primary battery and said secondary battery supply said loads with electricity and in which when said engine switch is connected with the starting point said primary control contact point and said tertiary control contact point move to their ON positions to make both of said primary battery and said secondary battery supply said engine starter and said loads with electricity in parallel and said secondary control contact point is switched to be connected with one of the terminal of (-) polarity of said primary battery and said secondary battery from the other of the terminals of (-) polarity of said primary battery and said secondary battery.
According to the present invention, when the engine switch is connected with the starting point for example by turning an engine switch, the engine starter is started by supplying it with electricity through both of the primary battery and the secondary battery in parallel.
After the engine switch is disconnected from the starting point the engine having started, the loads are supplied with electricity through either of the primary battery and the secondary battery, the generator charges the primary battery and the secondary battery in parallel and thus smooth restarting after stopping the engine can be realized.
Every time the engine switch is connected with the starting point, one of the primary battery and the secondary battery which ha
