Abstract

Disclosed is an apparatus and method for controlling a turn-on sequence of switches included in a parallel multi battery pack, including a processor that receives a switch voltage value from a voltage sensor coupled to a kth sequence switch unit (k is a turn-on sequence index, which is a natural number of 2 to n) before turning on the kth sequence switch, then turns on the kth sequence switch, subsequently receives a switch current value from a current sensor connected to the kth sequence switch, counts a watt energy value consumed in the kth sequence switch from the switch voltage value and the switch current value and determines the turn-on sequence of the first to nth switches in descending order from a switch having a greatest watt energy count value.
