BATTERY BUSBAR TEST TOOL, TEST METHOD AND SERVICE LIFE PREDICTION METHOD

A battery busbar test tool, test method and service life prediction method. The battery busbar test tool comprises: at least two busbars (2) connected in series, each busbar comprising two connection ends; and at least one adapter conducting bar (7), each adapter conducting bar (7) comprising two connection ends, and two adjacent connection ends of the adjacent busbars (2) being respectively connected to the two connection ends of the adapter conducting bar (7). The connection ends (1), not connected to the adapter conducting bar (7), of the first busbar (2) and the last busbar (2) are used for connecting to a power supply. The connection ends, connected to the adapter conducting bar (7), of the busbars (2), the connection ends of the adapter conducting bar (7), and pressure sensors (5) are successively stacked and are fixed by means of bolts (9) and nuts (8). The pressure sensors (5) are used for measuring values of pressure applied by the bolts (9) to the connection ends of the busbars (2). The test tool ca
