1. What is a discharge platform?
The discharge platform for nickel -metal hydride batteries usually refers to the voltage range of a relatively stable working voltage of the battery when the battery is discharged under a certain discharge system. The value is related to the discharge current. The larger the current, the lower its value.
2. What is the standard for battery?
The standard charging and discharge of the nickel -hydride battery specified in the IEC international standard is: first discharge the battery to 1.0V/support of 0.2C, then charging 0.1C for 16 hours, and put it for 1 hour, and put it to 1.0V/branch with 0.2C, with 0.2C to 1.0V/support. That is to charge the battery standard. In other words, the battery can be used to maximize and does not damage the battery.
3. What is charging efficiency?
Refers to the ratio of the capacity released by the battery under a certain discharge condition to a certain section voltage to the capacity of the battery capacity input; it can be calculated according to the following formula: charging efficiency = (discharge current* time of discharge to the dead voltage time/charging current* charging time )* 100%.
4. What is the power output of the battery?
The power output of the battery refers to the ability of the output power in the unit time. It is the P = U*I unit calculated based on the discharge current i and discharge voltage. The smaller the internal resistance of the battery, the higher the output power. The internal resistance of the battery should be less than the internal resistance of electrical appliances, otherwise the power consumption of the battery itself is greater than the power consumed by electrical appliances. This is not economical and may damage the battery. The increase in the increase in work temperature rises, and vice versa.
5. What is the self -discharge of the secondary battery? What is the self -discharge rate of different types of batteries?
The self -discharge indicates that the battery is putting for a period of time after the battery is put on hold for a period of time. After a period of time, the amount of electricity reserved accounted for a percentage of the capacity before shelving.
Generally speaking, self -discharge is mainly affected by the manufacturing process, materials, and storage conditions. Self -discharge is one of the main parameters to measure battery performance. The self -discharge of nickel -metal hydride batteries is usually because the hydrogen from the negative metal hydrogen is separated from the hydrogen storage alloy in the negative metal hydrogen, which is relieved from the negative electrode to the surface of the positive electrode and restored NIOOH to Ni (OH) 2, causing the loss of power.
Generally speaking, the lower the storage temperature of the battery, the lower the self-discharge rate, but it should also be noted that the temperature is too low or too high may cause the battery damage and cannot be used. The conventional battery requires the storage temperature range of -20 ~ 45 ° C. After the battery is fully charged and the road is put on hold for a period of time, a certain degree of self -discharge is normal. In addition, high -power batteries usually have large self -discharge, and the characteristics of the diaphragm also affect the self -discharge of the battery.
After the IEC standard stipulates that the nickel -metalized battery is fully charged, at the condition of 20 ± 5 ° C humidity of 65 ± 20%, the opening of the road is put on hold for 28 days, and the 0.2C discharge time reaches 3 hours and 15 minutes, respectively. (The self -discharge rate of nickel -metal hydride batteries is 30%/monthly)
