In an embodiment, a heating component is used to heat the circulation loop, and at least part of the air supply path passes through the circulation loop to take away the heat of the circulation loop.

[0033] In this way, according to the energy storage mechanism provided in the embodiment of the present application, when the ambient temperature of the energy storage mechanism is low, the heating component will heat the medium inside the circulation loop to increase the temperature of the medium. The heated regulating medium can exchange heat with the battery body, thereby heating the battery body, thereby reducing the resistance inside the battery pack body increased due to the cold, improving the current output of the battery pack in a low temperature environment and improving the stability of current regulation.

[0034] According to the energy storage mechanism provided in the embodiment of the present application, when the ambient temperature of the energy storage mechanism is high, the medium in the circulation loop will also circulate.

As an example, the inlet can be located below the liquid storage component, and the outlet can be at the top of the thermostatic water tank. Through the air induction slope of the inlet, the wind at the chassis can be naturally introduced into the air delivery path when the vehicle is driving, thereby taking away the heat of the medium inside the liquid storage component.

[0047] According to the energy storage mechanism provided in the embodiment of the present application, the energy storage structure can be detachably arranged in the box, so as to facilitate the fixing and removal of the energy storage structure.

Thus, the reinforcing members can both protect the energy storage mechanism and improve the connection strength between the shell and the box.

[0049] According to the energy storage mechanism provided in the embodiment of the present application, each reinforcing member can cross the boundary between the box body and the shell, thereby further improving the connection strength and protective measures between the shell and the box body.

[0050] The energy storage mechanism provided in the embodiment of the present application essentially provides a battery pack (i.e., the battery body, hereinafter referred to as the battery pack body) that can heat a battery pack in a low-temperature environment, thereby reducing the resistance inside the battery pack that increases due to the cold, and reducing the stability of the current output and current regulation in the low-temperature environment. At the same time, the battery pack can reduce the impact of heat accumulation on the battery capacity of the battery pack when the ambient temperature is high, thereby restoring normal power transmission intensity.

[0051] Specifically, the outside of the battery pack body 3 can be equipped with a side protective shell 1 and two sealing buckle plates 2 (thereby forming a shell as above, where the side protective shell 1 and the two sealing buckle plates also form part of the box body).

[0052] In the embodiment, two sealing buckle plates 2 are respectively installed on the top and bottom of the side protective shell 1, a thermostatic water tank 4 is installed on one side of the side protective shell 1, a heater 5 is installed on one side of the thermostatic water tank 4, and a micro water pump 6 and a micro water pump 7 are respectively installed on both sides of the thermostatic water tank 4, and the water inlet end of the micro water pump 6 and the water delivery end of the micro water pump 7 are both connected to the interior of the thermostatic water tank 4.

[0053] In the embodiment, a circulating temperature regulating tube 8 (i.e., a circulating pipeline) is installed at the water outlet end of the micro water pump 6. The circulating temperature regulating tube 8 extends to the inside of the side protective shell 1 and is located on the top of the battery pack body 3. The circulating temperature regulating tube 8 is in a folded shape. A temperature regulating plate 9 is installed on the circulating temperature regulating tube 8. The temperature regulating plate 9 is installed inside the side protective shell 1. The folded part of the circulating temperature regulating tube 8 is located inside the temperature regulating plate 9. The temperature regulating plate 9 is attached to the top of the battery pack body 3.

[0054] In the embodiment, during the daily operation of the battery pack body 3, when the ambient temperature is low, the heater 5 heats the temperature-regulating liquid inside the temperature-regulating water tank 4 to increase the temperature of the temperature-regulating liquid, and then the micro-water pump 6 on one side of the temperature-regulating water tank 4 draws the temperature-regulating liquid from the temperature-regulating water tank 4 and flows along the circulating temperature-regulating tube 8 inside the temperature-regulating plate 9 until it is pumped back into the temperature-regulating water tank 4 by the micro-water pump 7 to achieve circulation, so that the heated temperature-regulating liquid can pass through the circulating temperature-regulating tube 8 and the temperature-regulating plate 9 to heat the battery pack body 3 at the bottom, thereby reducing the resistance inside the battery pack body 3 increased due to the cold, and reducing the stability of the current output and current regulation in the low temperature environment.

[0055] In the embodiment, when the ambient temperature is high, the micro water delivery pump 6 and the micro water extraction pump 7 will also cooperate with each other to transport the temperature-controlled liquid in the temperature-controlled water tank 4 to the circulating temperature-controlled tube 8 for circulation, thereby performing heat exchange with the side protective shell 1 through the circulating temperature-controlled tube 8 and the temperature-controlled plate 9, taking away a large amount of heat generated during the operation of the side protective shell 1, reducing the impact of heat accumulation on the battery capacity of the battery pack body 3, and restoring normal power transmission intensity.

[0056] In the embodiment, a plurality of air ducts 10 (air delivery paths) with openings obliquely facing downward are installed at the bottom of the temperature-control water tank 4. The top ends of the air ducts 10 all penetrate the temperature-control water tank 4 and extend to the top of the temperature-control water tank 4, so that during the operation of the automobile, the air flow blown into the battery pack installation position through the air holes of the chassis can pass through the temperature-control water tank 4 through each air duct 10, thereby cooling the temperature-control water tank 4 itself, thereby ensuring the cooling effect of the temperature-control liquid inside the temperature-control water tank 4. By arranging a micro-water delivery pump 6 and a micro-water pump 7 to cooperate with each other to transport the temperature-control liquid, it is possible to prevent a single micro-water delivery pump 6 or a micro-water pump 7 from being insufficiently powered, thereby affecting the transport speed of the temperature-control liquid in the circulating temperature-control pipe 8, thereby affecting the temperature-control effect of the side protective shell 1. Two protective shells 29 are installed on one side of the side protective shell 1, and the micro-water delivery pump 6 and the micro-water pump 7 are respectively located inside the two protective shells 29.

[0060] In the embodiment, during the charging and discharging process of the vehicle, when the charging and discharging of the battery pack body 3 reaches a threshold, the backup battery 14 is switched to be charged and discharged, thereby preventing the battery pack body 3 from being over-discharged or over-charged, affecting the service life and operation safety of the battery pack body 3, the first socket 15 and the second socket 16 are respectively locked with the side protective shell 1 and the battery accommodating compartment 13 by the fastening bolts 19, and the external terminal 17 is locked with the battery box 11 by the fastening bolts 19, so that the adapter structure can be quickly disassembled, thereby facilitating the replacement of the backup battery 14, and at the same time, it can prevent the first socket 15 and the second socket 16 from loosening during the operation of the vehicle, affecting the stability of the output current.

[0061] In the embodiment, the thermal insulation cover 20 is provided so that the thermal insulation cover 20 can provide thermal insulation protection for the backup battery 14 to prevent the output current of the backup battery 14 from being difficult to reach the specified current intensity in a low temperature environment.
