BATTERY PACK STRUCTURE FOR ELECTRIC VEHICLES

摘要

A battery module (2), a junction box (5), and an LB controller (6) are mounted in the internal space of a battery pack case (1). A gap secured when the battery module (2) is installed in the internal space of the battery pack case (1) is used as a temperature adjustment air passage wherein temperature-adjusting air flows. The junction box (5) and the LB controller (6) are each arranged at separated positions facing one straight passage section (38a) of the temperature adjustment air passage. A weak-current harness (96) connecting the junction box (5) and the LB controller (6) is wired along the straight passage section (38a). As a result, smooth flow of temperature-adjusting air can be maintained in the harness connection of the junction box and the battery controller, while improving the workability of the harness wiring and the durability of the harness.
