How does the smart nickel-metal hydride battery charger discharge and measure the battery?

During the operation of the smart Ni-MH battery charger, a small part of the smart battery charger has the function of discharging. So how does the smart Ni-MH battery charger discharge? In all cases, is the working mechanism of the smart Ni-MH hydride charger the same? The discharge process of the smart Ni-MH charger is balanced during operation. In theory, attention should be paid to the discharge rate and depth of the smart Ni-MH charger. To put it simply, how to do the discharge rate (discharge current) and the cut-off voltage of the discharge, the charger discharge depth is more scientific? The general standard is: the smart Ni-MH charger can charge the battery between 0V and 1.4V. Conventionally, when the voltage of the Ni-MH battery is lower than 0.9V, the battery should not be used because it is lower than 1V. 'Excessive discharge' will lead to excessive evaporation of the electrolyte, followed by the excessive reaction of the negative electrode of the Ni-MH battery, which leads to the formation of a dielectric film. Change and reduce de-embedding capabilities. Loss of capacity. For example, if a 1800mAh battery is discharged at a rate of 0.1C, the discharge current is 180mAh, and the discharge current is usually small. Therefore, in the discharging of the smart nickel-metal hydride charger, from the perspective of the depth of discharge, the battery manufacturer should pay attention to the supplementary power; from the perspective of the discharge current, pay attention to the long flow of water. Under normal circumstances, nickel-metal hydride batteries have the possibility of reactivation, so you don’t have to mind the smart charger, the battery can be activated during the discharge process. This situation is most obvious on nickel separator batteries. When the smart nickel-metal hydride battery is placed for a long time, the battery itself also has a discharge phenomenon called self-discharge. So, how to discharge the Ni-MH battery during the self-discharge process? Mainly related to the ambient temperature. Generally speaking, at a temperature of (55°C), the monthly self-discharge rate is 10%, and at room temperature, the monthly loss is only 2-3%. Under normal circumstances, the smart discharge process of the Ni-MH battery charger usually uses a resistance short circuit to convert the power into heat, or the MOS tube is used to consume the battery power, and on some battery chargers with higher performance , The discharge efficiency can be constant and set, and the total energy stored in the battery can be measured by the constant discharge efficiency (discharge current) and discharge duration (discharge time) to identify the current state of the battery. These chargers have been industrialized and mass-produced for a long time. The measurement performance of individual chargers almost reaches the performance of professional equipment, such as RYDBATT's IC99, which has high capacity recognition accuracy.
