Cooling and heating device for battery pack

The utility model provides a cooling and heating device for a battery pack, which can efficiently cool or heat all single batteries forming the battery pack. A cooling and heating device (10) for a battery pack is configured such that: the battery pack is cooled and heated; wherein the number of the heat transfer components (11) is the same as that of the single batteries (2), and the elastic body(12) is arranged below the heat transfer components (11) and has restoring force. Heat is conducted between each heat transfer member (11) and each unit cell (2) by bringing a part of the outer surface of each heat transfer member (11) into contact with the lower surface of each unit cell (2), and each heat transfer member (11) is pressed against the lower surface of each unit cell (2) by an elastic body (12) having restoring force and disposed below the heat transfer member (11). 本实用新型提供一种能对构成电池组的全部单电池高效地冷却或加热的电池组用冷却兼加热装置。电池组用冷却兼加热装置(10)形成为下述结构：具有配置于电池组(1)下方的与单电池(2)数量相同的传热部件(11)、和配置于传热部件(11)下方且具有恢复力的弹性体(12)，通过使各传热部件
