Power conversion apparatus and junction box

A power conversion apparatus comprising:

• a charging apparatus that charges a battery using an external power supply;
• an inverter that converts a current of the battery from a direct current to an alternating-current and that supplies the alternating-current to a motor;
• and
• a junction box that relays electrical connection, wherein
• the inverter, the charging apparatus, and the junction box are housed in a single casing,
• the charging apparatus and the junction box are electrically connected to each other while the junction box and the inverter are electrically connected to each other, wherein
• the charging apparatus and the inverter are each connected to the battery via the junction box,
• the charging apparatus charges the battery via the junction box,
• the inverter is supplied with a current from the battery via the junction box,
• the junction box and the inverter are connected to each other via a bus bar, and
• the casing is internally divided into a plurality of spaces by a partition member, wherein the casing includes the inverter and the junction box in different spaces, respectively.
