Abstract
The invention relates to a circuit for identifying positive and negative poles of a battery under the condition of zero voltage. The circuit for automatically identifying the positive and negative poles of the battery is used for a charger and comprises an anti-reverse-connection circuit, wherein the anti-reverse-connection circuit is connected with a starter in parallel; and the capacity of the starter is adaptive to that of the charger and the battery and the starter is used for starting the anti-reverse-connection circuit when the battery is charged for the first time under the condition of low voltage or zero voltage of the battery. The circuit has the advantages of simple structure, high practicality, and capability of accurately identifying the positive and negative poles of the battery when the battery is charged for the first time under the condition of low voltage or zero voltage.
Description
Technical field:
The present invention relates to a kind of positive and negative electrode circuit of discerning under the storage battery zero-voltage state.
Background technology:
Now, reverse-connection preventing circuit has been designed in the charging set the inside, wrong both positive and negative polarity when preventing the storage battery charging, protection storage battery and charging set.But when storage battery low-voltage or zero-voltage state, reverse-connection preventing circuit can not be discerned positive and negative poles of battery, no matter be just to connect or reversal connection all can not be activated, charging set has just been lost normally the function to the storage battery charging.
Summary of the invention:
Purpose of the present invention is exactly at the problems referred to above, carries out innovative design on the basis of reverse-connection preventing circuit.Whether the present invention can be implemented in the both positive and negative polarity that still can judge storage battery under storage battery low-voltage or even the zero-voltage state and correctly is connected with two output terminals of charging set; Connecting correct reverse-connection preventing circuit opens and charges normal; The connection error reverse-connection preventing circuit can not start, and charging set is not worked.
Technical scheme provided by the invention is:
Automatically identification positive and negative poles of battery circuit is used for charging set, comprises reverse-connection preventing circuit, reverse-connection preventing circuit is parallel with a starter, the capacity of the capacity of starter and charging set and storage battery is suitable, is used under storage battery low-voltage or the zero-voltage state, first storage battery charge initiation reverse-connection preventing circuit.
Preferably, starter is thermistor or resettable fuse.
Preferably, starter by the parallel connection of a plurality of thermistors and or be composed in series, a plurality of thermistors are adjusted the capacity of starter with the mode of series and parallel.
Preferably, starter by the parallel connection of a plurality of resettable fuses and or be composed in series, a plurality of resettable fuses are adjusted the capacity of starter with the mode of series and parallel.
Preferably, starter by the parallel connection of several resettable fuses and several thermistors and or be composed in series, several resettable fuses and several thermistors are adjusted the capacity of starter with the mode of series and parallel.
The present invention is simple in structure, and is practical especially, can accurately know the both positive and negative polarity of storage battery when first storage battery charging of giving under low-voltage or the zero-voltage state, connects correct reverse-connection preventing circuit and opens and charge normal; The connection error reverse-connection preventing circuit can not start, and charging set is not worked, and reminds people correctly connects the both positive and negative polarity of charging set output terminal and storage battery.
Battery voltage is crossed low even is reached zero-voltage state, and reverse-connection preventing circuit can't be opened, and carries out operate as normal.If the both positive and negative polarity of storage battery is correct with being connected of charger, electric current is instantaneous to charge to storage battery by starter, and battery voltage returns to certain value, and reverse-connection preventing circuit is connected, the charging of charger bio-occlusion storage battery.If the connection error of the both positive and negative polarity of storage battery and charger, starter carries out instantaneous charging to storage battery, and battery voltage can not return to certain value, still not conducting of reverse-connection preventing circuit, and charger can't the charging of bio-occlusion storage battery.
