==Original Abstract Submitted==

the power supply device includes: a first battery module and a second battery module that can be charged by an external power source; a series circuit in which the first battery module and the second battery module are connected in series; a connection circuit that selectively forms a parallel circuit in which the first battery module and the second battery module are connected in parallel; a variable resistor provided in the connection circuit and interposed between the first battery module and the second battery module in the parallel circuit; and a control device that controls the resistance values of the opening and closing of the plurality of relays and the variable resistor. the control device is configured to be capable of performing a current adjustment process of continuously or stepwise lowering the resistance value of the variable resistor after the parallel circuit is formed by controlling the plurality of relays.
