Equipment module

An equipment module for switching between a series connection and a parallel connection of a first battery and a second battery, the equipment module comprising:

• a series relay configured to connect the first battery and the second battery in series;
• and
• a parallel relay configured to connect the first battery and the second battery in parallel, wherein
• the series relay includes:
• a series fixed terminal electrically connected to a current path;
• a series movable terminal configured to come into contact with and separate from the series fixed terminal;
• and
• a series rod extending through the series movable terminal so as to guide movement of the series movable terminal,
• the parallel relay includes:
• a parallel fixed terminal electrically connected to a current path that is different from the current path to which the series fixed terminal is connected;
• a parallel movable terminal configured to come into contact with and separate from the parallel fixed terminal;
• and
• a parallel rod extending through the parallel movable terminal so as to guide movement of the parallel movable terminal, and
• an extending direction of the series rod and an extending direction of the parallel rod are different from each other.
