摘要： A battery spacer includes: a storage case having a bottomed cylindrical shape in which a battery is stored; a lid part which closes an opening of the storage case; and a positive electrode relay terminal which is provided to the lid part, a part of which protrudes from a top surface of the lid part, and which abuts on a positive electrode terminal of the battery in the storage case. The lid part has a protruding section formed which protrudes further to the battery side than a terminal contact surface at which the positive electrode terminal of the battery abuts on the positive electrode relay terminal. The protruding section has a protruding length h, in the axial direction of the battery, from the terminal contact surface, shorter than the length H of the positive electrode terminal of the battery, and has an annular shape having a diameter R that is larger than the diameter r of the positive electrode terminal of the battery and is smaller than the diameter S of the battery in the radial direction of the battery.

摘要： A charging circuit includes a first power source circuit that supplies charging power to secondary batteries; a switch that controls the supply of the power; and a control device that performs switching control of the switch. The control device detects a voltage difference between the secondary batteries before starting charging; starts a timer and starts serial charging of the secondary batteries; on the condition that the voltage difference before the charging has been equal to or larger than a first threshold, if respective voltage values of the secondary batteries have both become equal to or larger than a second threshold before the timer expires, shortens a remaining time on the timer at that time point; and finishes the serial charging of the secondary batteries at the earlier of a time point when the secondary batteries have both become fully charged, or a time point when the timer has expired.
