Abstract

The invention relates to the technical field of battery detection, in particular to a constant-current and constant-power discharge device. The device comprises a microprocessor and a battery, wherein the microprocessor is electrically connected with a D / A (digital / analog) circuit, the D / A circuit is electrically connected with a V / I (voltage / current) circuit, the V / I circuit is respectively and electrically connected with an I / V (current / voltage) circuit and the battery, the I / V circuit is electrically connected with an AD (analog-digital) chip electrically connected with the microprocessor, the battery is electrically connected with the A / D (analog / digital) circuit and the A / D circuit is electrically connected with the microprocessor. With the adoption of the invention, the real-time collection and the adjustment of current value are realized; in order to adapt to wider current range and improve the precision and a 3-gear V / I and I / V conversion circuit is adopted; meanwhile, after one path of AD is added to collect battery voltage, the whole device can realize the function of constant-power discharging, that is the discharging current can be adjusted in a real-time manner according to the voltage value of the battery. Therefore, the requirements of the detection standard of battery discharging performance can be comprehensively satisfied.
