[0032] See also Figures 1 to 5 The present embodiment provides a battery insulation system, which includes a battery box 210, an insulation bag 220 and a circulation module 230, wherein the battery box 210 is configured to load the battery 100, the box body of the battery box 210 is provided with a compartment, the insulation bag 220 is accommodated in the compartment, the insulation bag 220 is provided with a first liquid inlet 221 and a first liquid outlet 222, the circulation module 230 includes a liquid storage tank 231, a liquid inlet pipe 232, a liquid outlet pipe 233, a circulation pump (not shown in the figure) and a heater (not shown in the figure), the liquid storage tank 231 is configured to store a liquid medium, the liquid inlet pipe 232 is connected to the first liquid inlet 221 and the liquid storage tank 231, the liquid outlet pipe 233 is connected between the first liquid outlet 222 and the liquid storage tank 231, the circulation pump is configured to circulate the liquid medium between the liquid storage tank 231 and the insulation bag 220 through the liquid inlet pipe 232 and the liquid outlet pipe 233, and the heater is configured to heat the liquid medium. When the temperature is low, the insulation bag 220 can play a role in heat preservation. Specifically, the circulation pump can circulate the liquid medium heated by the heater between the liquid storage tank 231 and the insulation bag 220, so that the battery 100 can be placed in an environment with a suitable temperature, thereby preventing the activity of the battery 100 from being affected by the temperature.

[0033] Based on the above, this embodiment sets a heat preservation bag 220 outside the battery 100, and injects a liquid medium into the heat preservation bag 220 through the circulation module 230. When the temperature is low, the heated liquid medium is injected into the heat preservation bag 220, so that the battery 100 can be placed in an environment with a suitable temperature, thereby preventing the activity of the battery 100 from being affected by the temperature. That is, this embodiment solves the problem of a significant reduction in the capacity of the battery 100 due to low temperature through the heat preservation bag 220 and the circulation module 230, and does not change the charging mode of the battery 100, thereby ensuring that the vehicle's cruising range will not be reduced due to low temperature, so as to avoid affecting the user's experience, and will not affect the service life of the battery 100.

[0034] In addition, in an extremely cold environment, the insulation bag 220 can help the battery 100 to quickly recover temperature, thereby preventing the battery 100 from being unable to work normally due to the outside temperature being too low. That is, in this embodiment, the insulation bag 220 has not only the insulation function, but also the emergency heating function. In other words, this embodiment can also use the insulation bag 220 to enable the vehicle to start normally under extremely cold conditions.

[0035] Moreover, in extremely cold environments, the thermal insulation bag 220 can also prevent the battery 100 from freezing due to the freezing of the internal liquid. That is, in this embodiment, the thermal insulation bag 220 also has the function of preventing the battery 100 from frostbite. In other words, this embodiment can also prevent the battery 100 from being damaged in extremely cold environments through the thermal insulation bag 220.

[0036] It is worth noting that in this embodiment, the heater is arranged in the liquid storage tank 231, and the heater can be selected as an electric heating plate or an electric heating rod, etc., and there is no specific limitation on this in this embodiment. Moreover, since the specific structure of the heater is a prior art, it will not be elaborated in this embodiment.

[0037] In addition, since the specific structure of the circulation pump is also prior art, it will not be described in detail in this embodiment.

[0038] It is also worth noting that, in this embodiment, the liquid medium may be selected as a heat-conducting medium such as water or heat-conducting oil, and this is not specifically limited in this embodiment.

[0039] Based on the above, in this embodiment, the battery box 210 includes an upper cover 211 and a lower bottom 212, and the upper cover 211 and the lower bottom 212 are spliced ​​to form the battery box 210. The upper cover 211 is provided with a first cavity 2111, and the lower bottom 212 is provided with a second cavity 2121. The first cavity 2111 and the second cavity 2121 are spliced ​​to form a compartment, thereby facilitating the disassembly and assembly of the battery 100 and the thermal insulation bag 220.

[0040] It is understandable that the upper cover 211 and the lower base 212 may be connected by bolt connection or snap connection, etc., and this is not specifically limited in the present embodiment.

[0041] In addition, a second liquid inlet 2112 and a second liquid outlet 2122 are respectively provided on the upper cover 211 and the lower bottom 212, wherein the liquid inlet pipe 232 passes through the second liquid inlet 2112 and is connected to the first liquid inlet 221, while the liquid outlet pipe 233 passes through the second liquid outlet 2122 and is connected to the first liquid outlet 222. That is, in this embodiment, for the insulation bag 220, the first liquid inlet 221 is located above the first liquid outlet 222, so that the liquid medium injected into the insulation bag 220 from the first liquid inlet 221 can flow out from the first liquid outlet 222 under the action of gravity, thereby realizing the circulation of the liquid medium.

[0042] Furthermore, in this embodiment, the compartment surrounds the periphery of the battery 100, so that the insulation bag 220 surrounds the periphery of the battery 100, thereby ensuring that when the temperature is low, the battery 100 is surrounded by an environment with a suitable temperature, thereby more effectively preventing the activity of the battery 100 from being affected by the temperature.

[0043] Furthermore, the heat preservation bag 220 is made of rubber material, so as to prevent the battery 100 from being damaged due to external impact on the battery box 210.

[0044] In addition to the heater, the circulation module 230 also includes a cooler (not shown in the figure), which is also arranged in the liquid storage tank 231. The cooler is configured to cool the liquid medium. During the operation of the battery 100, when the temperature of the battery 100 is too high, the cooler can cool the liquid medium. The circulation pump can circulate the liquid medium cooled by the cooler between the liquid storage tank 231 and the insulation bag 220, so as to cool the battery 100 and prevent the battery 100 from overheating and affecting its service life.

[0045] Based on the above, the battery insulation system in this embodiment has insulation function, emergency heating function, function of preventing the battery 100 from being frozen and cooling function, among which the insulation function, emergency heating function and function of preventing the battery 100 from being frozen are realized by a heater, while the cooling function is realized by a cooler, thereby being able to ensure vehicle performance while fully improving the service life of the battery 100.

[0047] Based on the above, the battery insulation system further includes a temperature sensor 240 , which is configured to detect the temperature of the battery 100 , so that the heater and the cooler can be started according to the temperature adaptability of the battery 100 .

[0048] Specifically, the battery insulation system also includes a controller (not shown in the figure), and the temperature sensor 240, the heater and the cooler are all electrically connected to the controller. The controller can control the start-up of the heater or the cooler according to the detection information of the temperature sensor 240.

[0049] It is understandable that since the specific structure of the temperature sensor 240 is a prior art, it will not be described in detail in this embodiment.

[0050] Further, based on the above, the battery box 210 includes an upper cover 211 and a lower bottom 212, wherein the upper cover 211 is provided with a wire outlet 2113, and the wire outlet 2113 is configured to pass wires, and the wires specifically include a power line of the battery 100 and a signal line of the temperature sensor 240, etc. The wires can pass through the battery box 210 through the wire outlet 2113, thereby facilitating the arrangement of the wires.
