[0004] An object of the present application is to provide a wire harness separator that can provide thermal protection for the wire harness in a battery, so as to improve the problems of wire harness damage and short circuit in the case of thermal runaway of the battery.

[0005] An embodiment of the first aspect of the present application provides a wire harness separator for a battery. The wire harness separator includes: at least one fluid discharge through-hole and at least one wire harness channel. Each fluid discharge through-hole is used to communicate with a corresponding explosion-proof valve of the battery, so that the explosion-proof valve discharges hot fluid through the fluid discharge through-hole. At least one wire harness channel, each wire harness channel extends along the length direction of the wire harness separator for the wire harness in the battery to pass through. The wire harness channel includes a first side portion and a connecting portion. The first side portion is located between the at least one fluid discharge through-hole and the wire harness, and is used to isolate the fluid discharge through-hole from the wire harness. The connecting portion is configured to shield the wire harness from above, so as to provide thermal protection for the wire harness in the case of thermal runaway of the battery.

[0006] In the technical solution of the embodiment of the present application, a wire harness separator with a wire harness channel is provided, which can provide thermal protection for the wire harness in a battery, so as to improve the problems of wire harness damage and short circuit in the case of thermal runaway of the battery.

[0007] In some embodiments, the wire harness channel further includes a second side portion disposed opposite to the first side portion, and the first side portion and the second side portion are configured to shield the wire harness from both sides. A wire harness separator having a wire harness channel including a connecting portion and two side portions can provide better thermal protection for the wire harness in a battery, so as to improve the problems of wire harness damage and short circuit in the case of thermal runaway of the battery.

[0008] In some embodiments, the wire harness separator further includes: at least one seal, and the at least one seal is respectively arranged on the bottom wall of at least one of the first side portion and the second side portion away from the connection portion along the length direction of the wire harness separator, and is used for providing additional thermal protection between the wire harness channel and the mounting surface of the battery for mounting the wire harness separator when the wire harness separator is mounted on the battery. By providing at least one seal, additional thermal protection can be provided between the wire harness channel and the mounting surface of the battery for mounting the wire harness separator when the wire harness separator is mounted on the battery, thereby further improving the problems of wire harness damage and short circuit in the case of thermal runaway of the battery.

[0009] In some embodiments, the wire harness separator further includes: at least one fixing member, and the at least one fixing member is respectively arranged on at least one side of both sides of the wire harness channel along the width direction of the wire harness separator, and is used for fixedly mounting the wire harness separator on the battery.

[0010] In some embodiments, the at least one wire harness channel includes two wire harness channels arranged side by side along the length direction of the wire harness separator for two wire harnesses in the battery to pass through respectively. Wherein, the at least one fluid discharge through hole is sequentially arranged between the two wire harness channels along the length direction of the wire harness separator. By providing two wire harness channels arranged side by side, separation of the two wire harnesses can be achieved. This helps to avoid cross-interference and entanglement between the wire harnesses, ensures isolation and independence between the wire harnesses, and thus improves the reliability and stability of wire harness routing. In addition, arranging the wire harness channels on both sides of the fluid discharge through hole can provide thermal protection for the wire harnesses in the battery to improve the problems of wire harness damage and short circuit caused by the ejection of hot fluid by the explosion-proof valve.

[0011] In some embodiments, the wire harness separator further includes: two seals, and each seal is arranged on the bottom wall of the first side portion of the corresponding one of the two wire harness channels away from the connection portion along the length direction of the wire harness separator.

[0037] Currently, from the perspective of the development of the market situation, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric vehicles, as well as in multiple fields such as military equipment and aerospace. With the continuous expansion of the application fields of power batteries, the market demand is also continuously increasing.

[0038] As an important structure in a vehicle, when a power battery is mechanically damaged, such as by a vehicle collision, a thermal runaway phenomenon will occur, and high-temperature and high-pressure gases and liquids will be generated inside the battery and ejected from the explosion-proof valve of the battery. These high-temperature and high-pressure fluids will directly impact or drip onto the wiring harness in the battery, causing the protective outer skin of the wiring harness to melt, resulting in the exposure and short circuit of the conductor.

[0039] The battery disclosed in the embodiments of the present application can be but is not limited to being used in power-consuming devices such as vehicles, ships, or aircraft. The power system of the power-consuming device can be composed of the battery disclosed in the present application. In this way, thermal protection can be provided for the wiring harness in the battery to improve the problems of wiring harness damage and short circuit in the case of thermal runaway of the battery.

[0040] Figure 1A schematic diagram of a wire harness isolation plate according to some embodiments of the present application is shown, where L indicates the length direction of the wire harness isolation plate and W indicates the width direction of the wire harness isolation plate. Figure 2 A cross-sectional view of a wire harness isolation plate 100 symmetrically arranged with a first wire harness channel 110a and a second wire harness channel 110b is shown.

[0041] Embodiments of the present application provide a wire harness isolation plate 100 for a battery. The wire harness isolation plate 100 includes at least one fluid discharge through-hole 140 and at least one wire harness channel 110. Each fluid discharge through-hole is used to communicate with a corresponding explosion-proof valve of the battery, so that the explosion-proof valve discharges hot fluid through the fluid discharge through-hole. Each wire harness channel 110 extends along the length direction L of the wire harness isolation plate 100 for a wire harness (not shown) in the battery (not shown) to pass through. The wire harness channel 110 includes a first side portion 112 and a connecting portion 116. The first side portion 112 is located between at least one fluid discharge through-hole 140 and the wire harness, and is used to isolate the fluid discharge through-hole from the wire harness; the connecting portion 116 is configured to shield the wire harness from above, so as to provide thermal protection for the wire harness in the event of a thermal runaway of the battery.

[0042] In the embodiments of the present application, the "wire harness isolation plate" may refer to a component for isolating and protecting the wire harness in the battery.

[0043] The wire harness isolation plate 100 according to the embodiments of the present application may include at least one wire harness channel 110, such as one, two or more. Although Figures 1 - 2 only the wire harness isolation plate 100 including two wire harness channels 110 is shown, it should be understood that depending on actual needs, other numbers of wire harness channels 110 are also possible. The wire harness channel 110 extends along the length direction L of the wire harness isolation plate 100, and the wire harness in the battery can be arranged in the wire harness channel 110.

[0044] The wire harness isolation plate 100 according to the embodiments of the present application may include at least one fluid discharge through-hole 140. Each fluid discharge through-hole 140 corresponds to an explosion-proof valve of the battery. The explosion-proof valve may be, for example, a weak area on the battery case. When a thermal runaway occurs in the battery, the high-pressure and high-temperature fluid (liquid and / or gas) inside the battery will damage the explosion-proof valve and eject the hot fluid through the corresponding fluid discharge through-hole 140. The fluid discharge through-hole 140 can guide the hot fluid.

[0045] The wire harness channel 110 includes a first side portion 112 and a connecting portion 116. Among them, the first side portion 112 is located between at least one fluid discharge through hole 140 and the wire harness, and can be used to isolate the fluid discharge through hole from the wire harness. The connecting portion 116 is configured to shield the wire harness from above. For example, in the case of thermal runaway of the battery, hot fluid sprays out from the explosion-proof valve, and the first side portion 112 and the connecting portion 116 in the wire harness channel 110 can isolate the wire harness from the hot fluid in two directions to largely protect the wire harness from corrosion by the hot fluid.

[0046] It should be understood that the first side portion 112 and the connecting portion 116 of the wire harness channel 110 are provided to provide thermal protection for the wire harness in the case of thermal runaway of the battery. The specific connection manner and shape of the first side portion 112 and the connecting portion 116 are not limited herein. For example, the connecting portion 116 can be fixedly connected or detachably connected to the first side portion 112; the included angle between the connecting portion 116 and the first side portion 112 can be formed at any angle capable of accommodating the wire harness; the connecting portion 116 connected to the first side portion 112 can be straight or arched.

[0047] In the technical solution of the embodiment of the present application, a wire harness isolation plate with a wire harness channel is provided, which can provide thermal protection for the wire harness in the battery to improve the problems of wire harness damage and short circuit in the case of thermal runaway of the battery.

[0048] According to some embodiments of the present application, the wire harness channel 110 further includes a second side portion 114 disposed opposite to the first side portion 112. Among them, the first side portion 112 and the second side portion 114 are configured to shield the wire harness from both sides of the wire harness.

[0049] In some embodiments, the wire harness channel 110 includes a first side portion 112 and a second side portion 114 opposite to each other and a connecting portion 116 connecting the first side portion 112 and the second side portion 114. Thus, the wire harness arranged in the wire harness channel 110 can be shielded and protected in three directions (i.e., both sides and above).

[0050] It should be understood that the specific connection manner and shape of the first side portion 112, the second side portion 114 and the connecting portion 116 are not limited herein. For example, the connecting portion 116 can be fixedly connected or detachably connected to the first side portion 112 and the second side portion 114; the included angle between the connecting portion 116 and the first side portion 112 and the second side portion 114 can be formed at any angle capable of accommodating the wire harness; the connecting portion 116 connected to the first side portion 112 and the second side portion 114 can be straight or arched.

[0051] A wire harness separator having a wire harness channel including a connecting portion and two side portions can provide better thermal protection for the wire harness in a battery to improve the problems of wire harness damage and short circuit in the case of thermal runaway of the battery.

[0052] According to some embodiments of the present application, the wire harness separator 100 further includes at least one seal 120. The at least one seal 120 is respectively arranged on the bottom wall of at least one of the first side portion 112 and the second side portion 114 away from the connecting portion 116 along the length direction L of the wire harness separator 100, and is used to provide additional thermal protection between the wire harness channel 110 and the mounting surface (not shown) of the battery for mounting the wire harness separator 100 when the wire harness separator 100 is mounted to the battery.

[0053] When the wire harness separator 100 is mounted to the battery, the bottom walls of the first side portion 112 and the second side portion 114 away from the connecting portion 116 are joined to the mounting surface of the battery for mounting the wire harness separator 100. When thermal runaway occurs in the battery, the high-temperature fluid generated may enter the wire harness channel through the gap between the bottom wall and the mounting surface, thereby causing damage to the wire harness.

[0054] In some embodiments, the wire harness separator 100 may further include at least one seal 120 to provide additional thermal protection between the wire harness channel 110 and the mounting surface of the battery for mounting the wire harness separator 100. The seal may be, for example, a high-temperature resistant sealing strip.

[0055] In some embodiments, when the wire harness separator 100 includes one wire harness channel 110 (not shown in the figure), the wire harness separator 100 may include one seal 120. For example, when the wire harness separator 100 only includes Figure 2 the first wire harness channel 110a shown in the left side, the wire harness separator 100 may include a seal 120 arranged on the bottom wall of the first side portion 112. Or, when the wire harness separator 100 only includes Figure 2 the second wire harness channel 110b shown in the right side, the wire harness separator 100 may include a seal 120 arranged on the bottom wall of the first side portion 112.

[0056] In some embodiments, when the wire harness separator 100 includes one wire harness channel 110 (not shown in the figure), the wire harness separator 100 may also include two seals 120. For example, when the wire harness separator 100 only includes Figure 2 the first wire harness channel 110a or the second wire harness channel 110b shown in the figure, seals 120 are arranged on the bottom walls of the first side portion 112 and the second side portion 114 of each wire harness channel.

[0057] It should be understood that the number and arrangement positions of the seals 120 can be selected according to actual needs or according to the number of wire harness channels 110 in the wire harness separator 100.

[0058] By providing at least one seal, when the wire harness separator is installed on the battery, additional thermal protection can be provided between the wire harness channel and the mounting surface of the battery for mounting the wire harness separator, thereby further improving the problems of wire harness damage and short circuit in the case of thermal runaway of the battery.

[0059] According to some embodiments of the present application, the wire harness separator 100 further includes at least one fixing member 130. The at least one fixing member 130 is respectively arranged on at least one side of the two sides of the wire harness channel 110 along the width direction W of the wire harness separator 100 for fixedly mounting the wire harness separator 100 on the battery.

[0060] In some embodiments, the wire harness separator 100 may further include a fixing member 130. The number of the fixing members 130 may be one or more. Depending on actual needs, the fixing member 130 may be arranged on either one side or both sides of the two sides of the wire harness channel 110 along the width direction W of the wire harness separator 100.

[0061] Reference Figure 1 and Figure 2 , the fixing member 130 may be, for example, a mounting buckle arranged on one side of the wire harness channel 110 for fixedly mounting the wire harness separator 100 on the battery.

[0062] By using the fixing member to fixedly mount the wire harness separator on the battery, the connection stability between the wire harness separator and the battery can be enhanced.

[0063] According to some embodiments of the present application, at least one wire harness channel 110 includes two wire harness channels 110 arranged side by side along the length direction L of the wire harness separator 100 for two wire harnesses in the battery to pass through respectively. At least one fluid discharge through hole 140 is sequentially arranged between the two wire harness channels 110 along the length direction L of the wire harness separator 100.

[0064] In some embodiments, reference Figure 1 and Figure 2 , the wire harness separator 100 may include two wire harness channels 110 arranged side by side, namely a first wire harness channel 110a and a second wire harness channel 110b. One or more fluid discharge through holes 140 arranged in sequence along the length direction L may be provided between the first wire harness channel 110a and the second wire harness channel 110b.

[0065] By providing two wire harness channels arranged side by side, the separation of two wire harnesses can be achieved. This helps to avoid cross-interference and entanglement between the wire harnesses, ensuring isolation and independence between the wire harnesses, thereby improving the reliability and stability of the wire harness routing. In addition, arranging the wire harness channels on both sides of the fluid discharge through-hole can provide thermal protection for the wire harnesses in the battery to improve the problems of wire harness damage and short circuit caused by the ejection of hot fluid from the explosion-proof valve.

[0066] According to some embodiments of the present application, the wire harness separator 100 further includes two seals 120. Each seal 120 is arranged on the bottom wall of the corresponding first side portion 112 of one of the two wire harness channels 110 along the length direction L of the wire harness separator 100, away from the connection portion 116.

[0067] In some embodiments, referring to Figure 2 , one seal 120 can be included in each of the first wire harness channel 110a and the second wire harness channel 110b arranged side by side of the wire harness separator 100. Each seal 120 is arranged on the bottom wall of the side portion (the first side portion 112 in Figure 2 ) of the corresponding wire harness channel closer to the fluid discharge through-hole 140 to better seal the side of the wire harness channel closer to the fluid discharge through-hole 140.

[0068] Arranging the seal on the bottom wall of the side portion of each wire harness channel closer to the fluid discharge through-hole can effectively improve the problems of wire harness damage and short circuit caused by high-temperature fluid passing through the gap between the mounting surface of the battery for mounting the wire harness separator and the wire harness channel, thereby providing additional thermal protection for the wire harness.

[0069] According to some embodiments of the present application, the wire harness separator 100 further includes two fixing members 130. Each fixing member 130 is arranged on the side of one of the two wire harness channels 110 away from at least one fluid discharge through-hole 140 along the width direction W of the wire harness separator 100 for fixedly mounting the wire harness separator 100 on the battery.

[0070] In some embodiments, referring to Figure 1 and Figure 2 , one fixing member 130 can be included in each of the first wire harness channel 110a and the second wire harness channel 110b arranged side by side of the wire harness separator 100. Each fixing member 130 is arranged on the outside of the corresponding side portion of the corresponding wire harness channel farther away from the fluid discharge through-hole 140 along the width direction W. For example, Figure 2 the outside of the second side portion 114 in. The fixing member 130 can be, for example, a mounting buckle for fixedly mounting the wire harness separator 100 on the battery.

[0071] By using two fixing parts to fixedly install the wire harness isolation plate on the battery, the connection stability between the wire harness isolation plate and the battery can be enhanced.

[0072] According to some embodiments of the present application, the wire harness isolation plate 100 is integrally formed.

[0073] The wire harness isolation plate 100 according to the above embodiments can be integrally formed, which can be realized by processes such as injection molding, die casting molding or stamping molding, for example.

[0074] The integrally formed wire harness isolation plate can have high structural strength and stability, and can better protect the wire harness and maintain the wiring stability of the wire harness.

[0075] The embodiments of the present application provide a battery, which includes the wire harness isolation plate in the above embodiments.

[0076] Since the battery includes the wire harness isolation plate in any of the above embodiments, the battery has the technical effects of the above wire harness isolation plate, which will not be elaborated here.

[0077] The embodiments of the present application provide an electrical device, which includes the battery in the embodiments of the second aspect of the present application, and the battery is used to provide electrical energy.

[0078] In some embodiments, refer to Figure 3 , Figure 3 is a schematic structural diagram of a vehicle provided by some embodiments of the present application.

[0079] The vehicle 1000 can be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. The vehicle 1000 is internally provided with a battery 700, and the battery 700 includes the wire harness isolation plate 100 in the above embodiments. The battery 700 can be arranged at the bottom or the head or the tail of the vehicle 1000. The battery 100 can be used for the power supply of the vehicle 1000. For example, the battery 700 can be used as the operating power source of the vehicle 1000. The vehicle 1000 can also include a controller 800 and a motor 900, and the controller 800 is used to control the battery 700 to supply power to the motor 900. For example, it is used for the working power requirements during the start, navigation and driving of the vehicle 1000.

[0080] In some embodiments of the present application, the battery 700 can not only be used as the operating power source of the vehicle 1000, but also be used as the driving power source of the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0081] The wire harness isolation plate of the present application will be further described below in conjunction with specific embodiments.

[0082] Refer to Figures 1 - 2, the wire harness separator 100 includes two wire harness channels 110 extending along the length direction L of the wire harness separator 100, namely the first wire harness channel 110a and the second wire harness channel 110b. The first wire harness channel 110a and the second wire harness channel 110b each include a first side portion 112 and a second side portion 114 opposite to each other and a connecting portion 116 connecting the first side portion 112 and the second side portion 114, so that the wire harness arranged therein can be shielded from both sides and above.

[0083] A plurality of fluid discharge through holes 140 are sequentially arranged between the first wire harness channel 110a and the second wire harness channel 110b, and each fluid discharge through hole 140 is used to surround a corresponding explosion-proof valve of the battery.

[0084] Each of the first wire harness channel 110a and the second wire harness channel 110b includes a seal 120. Each seal 120 is arranged on the bottom wall of the side portion of the corresponding wire harness channel closer to the fluid discharge through hole 140 along the length direction L to better seal the side of the wire harness channel close to the fluid discharge through hole 140.

[0085] The first wire harness channel 110a and the second wire harness channel 110b also each include a fixing member 130. Each fixing member 130 is arranged on the outer side of the corresponding side portion of the wire harness channel farther from the fluid discharge through hole 140 along the width direction W for fixedly mounting the wire harness separator 100 on the battery.
