Description

Technical Field

[0001] The utility model relates to the field of power storage cabinets, in particular to a power storage cabinet for a range-extended vehicle. Background Art

[0002] There are two main cooling methods for existing battery boxes: air cooling and water cooling. Air cooling mainly uses flowing cold air to take away the heat of the battery. This solution does not pose a safety risk to the energy storage cabinet, but the cooling effect is poor and the heat dissipation is uneven. It is suitable for energy storage cabinets with less heat generation. Water cooling mainly uses water flow to take away the heat of the battery to achieve the purpose of cooling. This solution has uniform and stable cooling and good cooling effect. It can be applied to energy storage cabinets with large heat generation, but water flow is a huge safety hazard for energy storage cabinets. In particular, the rupture of the water cooling pipe or the leakage of the pipe interface will cause serious harm to the energy storage cabinet. The existing battery box waterproofing methods mainly include improving the protection level of the battery box and reducing the possibility of pipe rupture and leakage. Improving the protection level of the battery box is difficult to design and has high cost. The general method to reduce the possibility of pipe rupture and leakage is to increase the strength of the water cooling pipe and reduce the number of pipe connectors. This solution cannot completely eliminate the possibility of pipe rupture causing harm to the battery and will increase the difficulty of installing the energy storage cabinet.

[0003] In the existing technology, such as the "energy storage cabinet" with Chinese authorization announcement number: CN210136925U, which includes multiple battery boxes, heat dissipation pipes connected to the heat dissipation interface of the battery box, and a protective component arranged outside the battery box, the protective component includes: an inner protective plate, which is buckled on the outside of the battery box, and the inner protective plate is penetrated with a perforation for penetrating the heat dissipation interface, so that the heat dissipation interface can pass through the perforation to connect to the heat dissipation pipe; an outer protective plate, which is connected to the inner protective plate, and the outer protective plate and the inner protective plate are enclosed to form an isolation cavity for accommodating the heat dissipation pipe. The inner protective plate and the outer protective plate form an isolation cavity, and the heat dissipation pipe is located in the isolation cavity, which can effectively reduce the impact range of water spray caused by damage to the heat dissipation pipe; the heat dissipation interface passes through the perforation and is connected to the heat dissipation pipe, that is, the connection part of the heat dissipation interface and the heat dissipation pipe is located in the isolation cavity, which prevents water leakage from the connection part from flowing into the battery box. Therefore, the protective component can provide double protection for water leakage, thereby improving the waterproofness of the energy storage cabinet.

[0004] In the prior art, when a power storage cabinet is used, since there are a large number of batteries inside the power storage cabinet, when a single battery fails, multiple batteries need to be disassembled and tested at the same time, which leads to the problem of inconvenient maintenance of the power storage cabinet.

[0005] Therefore, it is necessary to provide a range-extended vehicle power storage cabinet to solve the above technical problems. Utility Model Content

[0025] The input end of the voltage detector 5 is electrically connected to the output end of the battery stick 6, and the number of the voltage detectors 5 is several. By setting the voltage detector 5, when performing maintenance on the power storage cabinet, the voltage detector 5 can detect the voltage inside a single battery stick 6, and then display it in real time, thereby achieving a real-time detection effect of a single battery stick 6, avoiding the problem of needing to disassemble and detect the entire battery when a single battery fails, thereby improving the convenience of detection during battery troubleshooting, that is, improving the convenience of maintenance and repair of the power storage cabinet.

[0026] The limiting mechanism 7 includes a limiting plate 71, which is fixedly sleeved inside the box body 1, and a limiting hole 72 is provided inside the limiting plate 71. By setting the limiting mechanism 7, when the battery rod 6 is installed and fixed, the limiting plate 71 can limit the position of the battery rod 6 through the limiting hole 72, thereby avoiding the problem of position displacement when the battery rod 6 shakes, thereby improving the stability of the position of the battery rod 6.

[0027] The front shape of the conductive belt 8 is L-shaped, and the material of the conductive belt 8 is metal aluminum material; by setting the conductive belt 8, when the power storage cabinet is used, the conductive belt 8 can connect multiple panels of the box 1 in series, so that a current sealing effect can be formed inside the box 1, thereby achieving a shielding effect of static electricity inside the box 1, thereby avoiding the problem of electrical components being interfered with when static electricity is generated inside the box 1.

[0032] The working principle of the range-extended vehicle power storage cabinet provided by the utility model is as follows:

[0033] Step 1: First, when performing maintenance on the power storage cabinet, the voltage detector 5 can detect the voltage inside a single battery rod 6, and then display it in real time, thereby achieving the real-time detection effect of a single battery rod 6, so as to avoid the problem of disassembling the entire battery for detection when a single battery fails, thereby improving the convenience of battery troubleshooting detection, that is, improving the convenience of power storage cabinet maintenance and repair. When installing and fixing the battery rod 6, the limit plate 71 can limit the position of the battery rod 6 through the limit hole 72, thereby avoiding the problem of position displacement when the battery rod 6 shakes, thereby improving the stability of the position of the battery rod 6.

At this time, the closing plate 101 is lifted so that the closing plate 101 can be removed from the inside of the box 1, so that the box 1 can be opened, thereby facilitating the repair of the electrical components inside the box 1. When the battery rod 6 inside the box 1 generates a large amount of heat after working for a long time, the delivery pump 151 is started so that the delivery pump 151 can absorb the coolant inside the cooling box 14 and then deliver it to the cooling box 14 through the delivery pipe 152. Inside the box body 1, the coolant can quickly absorb the heat inside the box body 1 and then discharge it to the inside of the cooling box 14, thereby greatly improving the heat dissipation speed of the box body 1, that is, improving the heat dissipation speed of the battery rod 6, avoiding the problem of reduced working efficiency when the temperature of the power storage cabinet is high, thereby greatly improving the working efficiency of the power storage cabinet. When the coolant absorbs heat and discharges it to the inside of the cooling box 14, a plurality of heat sinks 16 can absorb the heat inside the cooling box 14 and then discharge it to the outside of the cooling box 14, thereby improving the heat dissipation speed of the cooling box 14.
