A battery temperature control device is provided with a heat medium circuit (10), a control unit (50), a battery temperature acquisition unit (53a), and a common flow path temperature acquisition unit (54a). The heat medium circuit circulates the heat medium by connecting the battery heat exchanger (11), the outside air heat exchanger (12), the heat medium pump (13), and the flow rate adjustment unit (14). The battery heat exchanger exchanges heat between a battery (B) and a heat medium. The external air heat exchanger is connected in parallel with the battery heat exchanger and exchanges heat between the heat medium and the external air. The flow rate adjustment unit adjusts the flow rate of the heat medium in a first path through which the heat medium flows via at least the external air heat exchanger, and the flow rate of the heat medium in a second path through which the heat medium flows by bypassing the external air heat exchanger. Furthermore, in the case of a low-temperature environment, the operation of the flow rate adjustment unit is controlled so that the flow rate ratio between the flow rate of the heat medium in the first path and the flow rate of the heat medium in the second path is adjusted so that the battery temperature becomes a preset reference temperature.
电池调温装置具有:热介质回路(10)、控制部(50)、电池温度获取部(53a)及共用流路温度获取部(54a)。热介质回路将电池用热交换器(11)、外气热交换器(12)、热介质泵(13)及流量调整部(14)连接起来使热介质循环。电池用热交换器使电池(B)与热介质进行热交换。外气热交换器相对于电池用热交换器并联地连接,并使热介质与外气进行热交换。流量调整部调整供热介质至少经由外气热交换器流通的第一路径中的热介质的流量和供热介质绕过外气热交换器而流通的第二路径中的热介质的流量。并且,在低温环境的情况下,控制流量调整部的工作,从而调整第一路径中的热介质的流量与第二路径中的热介质的流量的流量比,以使电池温度成为预先设定的基准温度。
