Abstract

The invention discloses a device for actively adjusting a battery voltage to an open circuit voltage, which comprises a charging and discharging adjustment mechanism, a voltage source, a battery, a current meter for measuring battery current changes, a voltmeter for measuring a battery voltage change direction and judging an over voltage state or a voltage drop state, an analog to digital signal converter, a logic controller for calculating and acquiring a region where the open circuit voltage is and giving a hedge current value, and a digital to analog signal converter. Through the above mode, according to the device for actively adjusting the battery voltage to the open circuit voltage provided by the invention, the open circuit voltage can be restored in a short time when a load is removed for the battery, the battery can be measured and used conveniently, the measurement precision is improved, and the measurement time is shortened.

Description

technical field [0001] The invention relates to a voltage regulating device, in particular to a device for actively regulating the open-circuit voltage of battery voltage. Background technique [0002] Batteries are affected by their internal impedance and can experience overvoltage (charging) or voltage drop (discharging) under a current load. In this case, the state of charge of the battery cannot be determined by measuring the voltage. Even after the current load is removed, depending on the temperature and the performance of the battery itself, it is necessary to wait 1 to 2 hours for the measured voltage to return to the open circuit voltage. Long waiting times are often unrealizable in practical applications of batteries. Contents of the invention [0003] The technical problem mainly solved by the present invention is how to provide a method to restore the battery to the open circuit voltage in a short time after the load is removed, so as to facilitate the measur...
