The electrical component integrated module 100 can control the charging environment of the battery, such as adjusting the charging temperature of the battery, so that the battery can maintain efficient charging at a suitable temperature. In addition, all components of the electrical component integrated module 100 are integrated together, with high integration, small space occupation, and easy use.

[0023] The electrical component integrated module 100 includes a housing 1 and a battery control assembly 2. The battery control assembly 2 is integrated inside the housing 1, so that the housing 1 can not only provide protection for the battery control assembly 2, but also facilitate integration of the battery control assembly 2, and is easy to use.

[0024] The outer shell 1 is provided with a connected accommodating cavity (not shown in the figure) and a heat dissipation hole 11. The heat dissipation hole 11 connects the accommodating cavity and the external air, so that the heat generated by the battery control component 2 located in the accommodating cavity during operation can be dissipated to the outside through the heat dissipation hole 11, which is beneficial to the heat dissipation of the battery control component 2. Figure 1 There are multiple heat dissipation holes 11 in the illustrated embodiment, and the multiple heat dissipation holes 11 are arranged at intervals along the length extension direction of the housing 1, which is beneficial to improving the heat dissipation efficiency of the accommodating cavity.

[0025] refer to Figure 3 The battery control assembly 2 includes a current input line 21, a fuse 22, a current sensor 23, a current output line 24, a heating element 25 and a control element 26 which are arranged in the accommodating cavity and connected in sequence along the line. The control element 26 and the heating element 25 are both connected in parallel between the current sensor 23 and the current output line 24. The parallel connection here can be understood as a direct connection, or an indirect connection through other components.

[0026] The control element 26 is used to detachably connect to an external controller, which may be a remote controller, a touch screen, or other terminals that can be used for manual control. When the control element 26 is connected to the external controller, the staff can hold the external controller to control the working performance of other related components of the battery control assembly 2, such as controlling the heating element 25 to heat or stop heating the battery.

[0027] The heating element 25 is used to detachably connect to an external heating source, which may be, for example, an electric heating film or other heating element capable of heating the battery. When the heating element 25 is connected to the external heating source, under the control of the control element 26, the external heating source can emit heat of a preset temperature to heat the battery, thereby improving the charging efficiency of the battery.

[0028] The other end of the current input line 21 away from the fuse 22 can be used to connect to an external power source, and the current output line 24 can be used to connect to a battery so that the external power source can charge the battery through the battery control assembly 2.

[0029] The fuse 22 can be used to automatically disconnect the circuit when the current in the circuit is too large, so as to protect the circuit.

[0030] The current sensor 23 is used to detect the current size of the circuit, and the current size can be viewed through an external controller. For example, the external controller can be a controller with a display screen, and the current size can be observed through the display screen.

The heating wire terminal 252 is used for detachably plugging in an external heating source so that the external heating source can heat the battery, and charging the battery at a suitable temperature is conducive to improving the charging efficiency. The heating fuse 251 can automatically cut off the circuit when the current flowing through the external heating source is too large to protect the circuit. The heating wire terminal 252 can be detachably plugged in with the external heating source to facilitate the replacement of the external heating source, or when not in use, the external heating source can be disassembled to facilitate carrying the electrical component integrated module 100.

[0032] The input end of the heating relay 253 is connected in parallel between the current sensor 23 and the current output line 24 to receive the current transmitted by the current input line 21. The heating relay 253 can switch between the circuit and the circuit break to control the external heating source to be connected to the circuit or not connected to the circuit, thereby controlling the external heating source to heat the battery or suspend heating. In other embodiments, when it is not necessary to control the switch of the external heating source, the heating relay 253 may not be provided.

[0033] In one embodiment, the control component 26 includes a control relay 261, a control line terminal 262 and a connecting line 263. The input end and the output end of the control relay 261 are respectively connected to the current sensor 23 and the current output line 24, and the output end of the control relay 261 is also connected to the input end of the heating relay 253.

[0034] One end of the control line terminal 262 is connected to the heating fuse 251 through the connecting line 263, and the other end of the control line terminal 262 can be detachably plugged into an external controller. When the control line terminal 262 is plugged into the external controller, the external controller can be connected to the circuit. The staff can control the control relay 261 to open or close the circuit by operating the external controller, thereby controlling the external power supply to charge the battery or suspend charging.

[0035] The housing 1 can be a whole or can be made up of multiple parts that are detachably connected. In one embodiment, the housing 1 includes a base 12 and an upper cover 13, and a receiving groove (not shown in the figure) is provided on the side of the upper cover 13 facing the base 12. When the upper cover 13 is connected to the base 12, a receiving cavity is formed between the groove wall of the receiving groove and the base 12, which is used to receive multiple components included in the battery control assembly 2.

[0036] In one embodiment, the base 12 has a plurality of fixed bases 121 , and the fuse 22 and the current sensor 23 are fixed to the fixed bases 121 by screws.

[0037] In one embodiment, the upper cover 13 is provided with a wire entry hole 131, a wire exit hole 132 and a terminal wire outlet 133 connected to the accommodating cavity. The current input wire 21 extends into the accommodating cavity through the wire entry hole 131, the current output wire 24 extends from the accommodating cavity through the wire exit hole 132, and the terminal heads of the heating element 25 and the control element 26 extend through the terminal wire outlet 133, specifically, the control wire terminal 262 and the heating wire terminal 252 extend through the terminal wire outlet 133, so as to facilitate the detachable plug-in of the external heating source and the external controller.

[0038] In one embodiment, the upper cover 13 is provided with a first through hole 134, and the base 12 is provided with a screw hole 122 and a second through hole 123. The first through hole 134 is used for a screw to pass through so that the screw is threadedly connected to the screw hole 122, thereby completing the connection between the upper cover 13 and the base 12. The second through hole 123 is used for a screw to pass through so that the screw is threadedly connected to the installation position, and there are many types of installation positions, such as a charging pile.
