Battery pack charge and discharge detection equipment

Abstract

The invention discloses battery pack charge and discharge detection equipment, and solves the problem of poor heat dissipation of the existing modular charge and discharge detection equipment. The keypoints of the technical scheme are that the battery pack charge and discharge detection equipment comprises an isolation transformer, an AC side capacitive inductor module, an AC / DC module, a DC / DC module, a DC side capacitive inductor module and a battery pack which are electrically connected with an AC power supply in turn. The AC / DC module and the DC / DC module are fixed in the first space. TheAC side capacitive inductor module and the DC side capacitive inductor module are fixed in the second space. The isolation transformer is fixed in the third space. According to the battery pack charge and discharge detection equipment, modular installation of the equipment can be guaranteed to keep the cabinet clean and tidy and make the wiring clear and convenient for maintenance, and the heat dissipation performance can also be improved so as to ensure stable operation of the equipment; and different modules are arranged in different spaces of the mounting bracket so as to make the structural distribution of all the modules more reasonable and tidy.

Description

technical field [0001] The invention relates to battery charge and discharge technology, in particular to battery pack charge and discharge detection equipment. Background technique [0002] At present, there are two main methods of charging and discharging detection equipment for battery packs, one is the equipment installed in the component structure, and the other is the equipment with the modular structure of the overall components. [0003] Fragmented installation, the components are opened in the cabinet as a whole, the layout is messy, the structure inside the cabinet is not neat, it is difficult to give people an aesthetic feeling, and the wiring is not neat, the components in the cabinet are placed unevenly, the maintenance space is small, and it is difficult to It is convenient for installation and maintenance; but because the device is opened in the cabinet as a whole, the heat dissipation effect is better.

Problems solved by technology

[0003] Fragmented installation, the components are opened in the cabinet as a whole, the layout is messy, the structure inside the cabinet is not neat, it is difficult to give people an aesthetic feeling, and the wiring is not neat, the components in the cabinet are placed unevenly, the maintenance space is small, and it is difficult to It is convenient for installation and maintenance; but because the device is opened in the cabinet as a whole, the heat dissipation effect is better

[0004] As for the modular structure of the overall components, except for the main switch and the isolation transformer in the cabinet, the rest of the components are arranged in the module, the structure is neat, and it gives a good visual effect; usually the AC side capacitor inductor and AC / DC module are integrated into a One module, while the DC side capacitor inductor and DC / DC module are integrated into another module; however, the structural characteristics of electrical equipment, especially inductive components, make it impossible to dissipate heat through a radiator like a power module. Concentrated in the module, it is difficult to effectively discharge the module in time, so the longer the module is used, the higher the internal temperature of the module will be. Long-term use may even affect the normal operation of the module, and there are too many components in the module, which makes the overall weight of the module heavier, and installation and handling are extremely difficult. Inconvenient, deviates from the original intention of the modular structure to facilitate installation
