The utility model provides capacitor battery formation system equipment and a charge-discharge method aiming at formation in a capacitor battery production process. Capacitor battery charge/discharge steps are formulated according to correlated characteristics of capacitor batteries, and one-to-one charge/discharge equipment is used for forming capacitor batteries, so that the interaction effect among the batteries is avoided. Charge/discharge voltage, charge/discharge current and charge/discharge time are automatically set, charge/discharge information graphs are drawn, and the manual intervention is not needed. The capacitor battery formation equipment comprises a binding post (1), a battery charger (2), a signal collector (3), a discharge load (4), a charge controller (5), a discharge controller (6), a main processor (7), a display circuit (8), a communication circuit (9) and an upper computer (10).
