The high tension storage battery of the methodological bipolar type which diagnoses the cutting of load electric power system of the electric battery and the vehicle and the operation of the device

摘要

The present invention relates to a method of diagnosing the operational state of the device (10) for connection and disconnection high voltage battery of the bipolar type (12), onboard power systems of bipolar type of the vehicle both with (14). The device (10), a power relay has a first arranged between the first terminal of the power system (18) terminal of the first battery (12) and (14) and (20) and (16), Power second relay is arranged between the second terminal of the power system (24) terminal of the second battery (12) and (14) and (26) and (22), the power relay of the first (16 comprises a series arrangement precharge third relay which is connected in parallel with) and (28) pre-charge resistor (30) and (28, 30), the method 2 (10) cutting / connection device and measuring the voltage of Tsu and _(V 1, V _2), and it is compared with a predetermined value of voltage representing the failure (10) cutting / connection device, the measured voltage of _(V 1, V _2), and a to diagnose the fault relay (16,22,28) on the basis of the result of the comparison. In accordance with the present invention, the voltage to be measured, the first between the second relay which is arranged (14) side-board power system (18) terminal of the first battery (12) and (22) a second voltage between the second terminal (20) and terminal voltage _{(V 1),} the first vehicle power system (14) and (26) is the _{(V 2).}
