Description

technical field [0001] The present disclosure relates to the technical field of power battery testing, and in particular to an intelligent battery testing device, system and method for a power monitoring device. Background technique [0002] With the development of the power grid, more and more smart terminals are used in the production, operation and maintenance of the power grid. As the energy source of the whole terminal, the battery is the basic condition for the normal operation of the whole terminal. The stability of the battery and the actual capacity that can be supplied to the load during the discharge process are of great significance to ensure the safe operation of power equipment. [0003] At present, the most widely used high-power battery charging technology is realized by phase-controlled rectification of thyristors. The AC side current waveform is seriously distorted, the power factor is low, and the power grid is seriously polluted. Moreover, the degree of ...

Problems solved by technology

[0003] At present, the most widely used high-power battery charging technology is realized by phase-controlled rectification of thyristors. The current waveform on the AC side is severely distorted, the power factor is low, and the power grid is seriously polluted. Moreover, the degree of automation is low, the operation is complicated, and it is prone to failure and reliable. The performance is not high; the discharge process usually passes through a first-level electric energy conversion device, which consumes electric energy in the form of heat energy through resistance, resulting in a great waste of energy, and the high temperature affects the working environment

Although the traditional test method can easily realize the charging and discharging equipment of the equipment, the heat generated by the discharge will cause energy waste, and the environmental stability and safety during the battery test process cannot be guaranteed
