Description

The on-board energy storage device mainly includes a battery pack with multiple battery groups and an energy storage inverter, which can convert, protect, store energy, and control the battery pack through the energy storage inverter.

[0003] In the process of implementing the embodiments of the present application, the inventors found that: at present, the battery pack and the energy storage inverter of the vehicle-mounted energy storage device are placed in the same chamber, and the battery pack and the energy storage inverter are the main heat sources in the vehicle-mounted energy storage device. When the battery pack and the energy storage inverter are placed in the same chamber and dissipated by air cooling, the guide fan will drive the airflow to cover the battery pack and the energy storage inverter at the same time. Due to the dispersion of the airflow, the airflow cannot cover the battery pack and the energy storage inverter separately. Therefore, the airflow cannot dissipate the heat of the battery pack and the energy storage inverter separately, and thus cannot accurately dissipate the heat of the battery pack and the energy storage inverter, resulting in low overall heat dissipation efficiency of the vehicle-mounted energy storage device.

[0032] For the above energy storage devices, see Figures 1 to 3 The number of battery packs 31 and the number of first guide fans 32 are both several, and the number of battery packs 31 and the number of first guide fans 32 are the same. Several battery packs 31 and first guide fans 32 are all arranged in the first heat dissipation channel, and one battery pack 31 and one first guide fan 32 are installed and connected correspondingly, so that one battery pack 31 can achieve precise heat dissipation under the action of one first guide fan 32, and then as the number of battery packs 31 and the first guide fan 32 increases, not only the overall energy storage capacity of the energy storage device can be effectively improved, but also the overall heat dissipation efficiency of the energy storage device can be effectively improved, so as to increase the energy storage capacity of the energy storage device while avoiding reducing the heat dissipation efficiency of the energy storage device. In addition, as the number of battery packs 31 and first guide fans 32 increases, in order to save space in the shell 1 for installing the battery packs 31 and the first guide fans 32 and avoid the energy storage device from being too large, several battery packs 31 are installed in an array stacking manner, and several first guide fans 32 are installed in an embedded manner.

By providing the first air outlet 13 and the second air outlet 15 on the top panel 17, and the first air inlet 12 and the second air inlet 14 on the side panel assembly 16, the probability of hot air discharged from one heat dissipation channel entering another heat dissipation channel can be reduced, thereby avoiding mutual interference between the first heat dissipation channel and the second heat dissipation channel.

[0034] Further, for the above-mentioned flow guide component 2, please refer to Figures 3 to 5The guide assembly 2 includes a guide plate 21, the top of which is connected to the top plate 17, the bottom of which is connected to the bottom plate 18, the side of which is fixed to the side plate assembly 16, and the guide plate 21 is arranged in an arc shape. The guide plate 21 is used to guide the airflow in the first heat dissipation channel to be discharged obliquely upward along the first air outlet 13 and to guide the airflow in the second heat dissipation channel to be discharged obliquely upward along the second air outlet 15. In the above manner, the first air outlet 13 and the second air outlet 15 can reduce the dead angle encountered in the process of discharging hot air obliquely upward to reduce resistance, thereby making the first heat dissipation channel and the second heat dissipation channel more unobstructed, thereby reducing the retention of hot air in the first heat dissipation channel and the second heat dissipation channel, and effectively improving the heat dissipation efficiency of the first heat dissipation channel and the second heat dissipation channel. It can be understood that in addition to being arranged in an arc shape, the guide plate 21 also includes but is not limited to being arranged in an inclined or curved shape, and only needs to drive the first air outlet 13 and the second air outlet 15 to discharge hot air obliquely upward.

[0035] Further, for the side panel assembly 16, please refer to Figures 3 to 5 The side panel assembly 16 includes a first side panel 161, a second side panel 162, a third side panel 163 and a fourth side panel 164, which are connected end to end in sequence, the first side panel 161 and the third side panel 163 are arranged opposite to each other, the second side panel 162 and the fourth side panel 164 are arranged opposite to each other, the opposite sides of the guide plate 21 are respectively connected to the first side panel 161 and the third side panel 163, the first air inlet 12 includes a first sub-air inlet 121, a second sub-air inlet 122 and a third sub-air inlet 123, the first sub-air inlet 121 is arranged on the first side panel 161, the second sub-air inlet 122 is arranged on the second side panel 162, the third sub-air inlet 123 is arranged on the third side panel 163, and the second air inlet 14 is arranged on the fourth side panel 164.

By providing the first gap 313 between any two adjacent battery packs 312, a plurality of first gaps 313 can be formed, so that the flowing airflow inside the first heat dissipation channel flows through the plurality of first gaps 313, and the flowing airflow can at least contact one side of each battery pack 312, thereby increasing the contact area between the battery pack 312 and the flowing air, thereby achieving accurate heat dissipation of the plurality of battery packs 312, improving the heat dissipation efficiency of the battery pack 31, and helping to improve the overall heat dissipation efficiency of the energy storage device.

[0038] Furthermore, for the above battery pack 31, in order to further improve the heat dissipation efficiency of the battery pack 31, please refer to Figure 3 , and please also refer to Figures 6 to 8The watch case 311 includes a first side wall 3111, a second side wall 3112, a third side wall 3113 and a fourth side wall 3114 which are connected end to end in sequence.
