Abstract

The invention discloses an efficient and energy saving type environmentally-friendly battery detection device. The device comprises an electric supply input, a two-way AC / DC, a two-way DC / DC, a two-way DC constant-current and constant-voltage module converter and a load battery which are sequentially connected; the two-way DC constant-current and constant-voltage module converter comprises a capacitor, an inductor and a switching tube; the switching tube comprises a voltage increase switching tube and a voltage decrease switching tube; the inductor is connected in series with the voltage decrease switching tube; the voltage increase switching tube and the capacitor are connected in parallel to two ends of a circuit; the control ends of the switching tubes are respectively connected with MOSFET driving circuits which are connected to a PWM pulse modulation module. According to the efficient and energy saving type environmentally-friendly battery detection device, the PWM pulse modulation module controls the charging voltage and current during charging and keeps the voltage and current constant, so that the adjusting loss can be reduced; when in discharging, the electricity energy released from the load battery is inverted through the two-way AC / DC into sine alternating AC current to be returned to a power grid, and therefore, the electricity energy can be saved, no heat is generated, the investment of radiating devices can be reduced, and the environment can be protected.

Description

technical field [0001] The invention relates to secondary battery charging and discharging equipment, in particular to a high-efficiency power-saving type environmental protection battery detection device. Background technique [0002] During the production process, the battery needs to be activated after several times of charging and discharging, and the capacity of the battery is detected at the same time. The traditional practice is to connect a power tube in the charge and discharge circuit for linear amplification. When the battery is charging, it requires constant current charging, and the power tube is used to adjust the charging current to maintain a constant current. Because the charging voltage is unstable, the voltage margin and adjustment range set by the power tube are large, and the loss is large; when the battery is discharged, the The power tube is used to convert electric energy into heat energy for heat dissipation, which not only wastes electric energy, b...

Problems solved by technology

When the battery is charging, constant current charging is required, and the power tube is used to adjust the charging current to maintain a constant current. Because the charging voltage is unstable, the voltage margin and adjustment range set by the power tube are large, and the loss is large; when the battery is discharged, The power tube converts electric energy into thermal energy for heat dissipation, which not only wastes electric energy, but also causes the temperature of the surrounding environment to rise. In order not to affect the work, the detection equipment must also be equipped with a powerful cooling device, which wastes resources and increases costs.
