The invention discloses a battery charging and discharging device and a management circuit, wherein electrical parameters on the whole circuit are collected by an electrical parameter collecting unit, collected data is transmitted to a micro control unit, according to received electrical parameters and / or preset switching frequency, the micro control unit controls a drive circuit to output driving signals to a first switching circuit and a second switching circuit, thereby controlling the through-current directions of the first and second switching circuits and shifting charging and discharging of the battery to be managed, because the charging circuit is in series connected with an inductance coil, current cannot be suddenly increased so as to protect the whole charging circuit and ensure its security, besides, through an external power supply, the battery can be charged and the inductance coil can be gathered with electric energy, at some point, the inductance coil can release the gathered electric energy to charge the battery and to recycle the energy.
Description
technical field [0001] The invention relates to the technical field of batteries, in particular to a battery charging and discharging device and a management circuit. Background technique [0002] With the wide application of power electronic devices, there are various unnecessary losses in the process of electric energy transmission of stationary batteries. For example, when charging a battery system, the battery is often burned because the voltage of the power supply system is higher than the rated voltage of the battery. In addition, when the battery starts to be charged externally, the current will increase instantaneously, which inevitably has some impact on some circuit components. It is likely to reduce the life of the components or even burn the components, and there is also some damage to the battery itself. [0003] At the same time, as the energy crisis becomes more and more serious, and people's awareness of energy conservation and environmental protection becom...
