The invention provides a battery which comprises a shell, a partition plate and a heat insulation medium. The space in the shell is divided into a first chamber and a second chamber by the partition plate, the first chamber is used for accommodating a battery core pack, the second chamber is used for accommodating a circuit assembly, and the heat insulation medium is connected to the partition plate. When the environment temperature is changed from low temperature to high temperature, the battery core bag can keep low temperature for a long time due to large heat capacity, the heat insulation medium connected to the partition plate can prevent the battery core bag from transmitting/radiating the low temperature to the circuit assembly, and therefore the surface temperature of the circuit assembly is higher than the dew point temperature of air, the condensation phenomenon of the circuit assembly is effectively avoided, the failure rate of the circuit assembly is reduced, and the reliability of the battery is improved.

    本申请提供一种电池,包括外壳、隔板和隔热介质,隔板将所述外壳内的空间分隔为第一室和第二室,所述第一室用于容纳电芯包,所述第二室用于容纳电路组件,所述隔热介质连接至所述隔板。当环境温度从低温向高温转变时,电芯包因热容量较大,将较长时间保持低温,本申请中连接至隔板上的隔热介质将阻挡电芯包将自身的低温传递/辐射给电路组件,这样电路组件的表面温度将高于空气露点温度,有效避免了电路组件产生凝露现象,降低电路组件的失效率,提高电池的可靠性。
