3.0.1 Storage Battery
Equipment adopting the conductor to connect two or more single battery as the energy source;
3.0.2 Acidspray-proof Lead-acid Battery
The compartment between the battery well and the battery is sealed so that the gas generated in the battery is discharged from the acid protection plug. The pole is mainly made of lead. The electrolyte is a kind of sulphuric acid solution. It can be divided into the acidspray-protection and exploration-prevention lead-acid battery and the acidspray-proof and hydrogen-eliminating lead-acid battery and is called acidspray-proof lead-acid battery for short.
3.0.3 Valve Regulated Sealed Lead-acid Battery
During the regular operation, the battery keeps the airtightness and fluid tight state. When the internal gas pressure exceeds the preset value, the relief value can be opened automatically and release the air. When the internal gas pressure is reduced, the relief value can be closed automatically to prevent the external air entering the inside of the battery so that it is sealed. Within the service life of the battery, under the regular service conditions, no additional electrolyte is needed.
3.0.4 Nickel-cadmium Battery
The anode active materials are mainly made from the nickel and the cathode active materials are the alkaline battery made of cadmium.
3.0.5 System
System herein refers to the combination of the equipment and lead (circuit) working under a common nominal voltage.
3.0.6 Nominal Voltage
The voltage set to the system.
3.0.7 Rated Voltage for Equipment
According to the stated working conditions of the electric equipment, the voltage decided by the manufacturer.
3.0.8 Floating Charge
Under the regular operation, the charging equipment is responsible for the regular load and charging the storage battery to supplement the self discharge of the battery so that the battery can be in the backup state under the full-capacity state.
3.0.9 Equalizing Charge
To compensate the uneven voltage generated in the service process and to make the voltage restored to the stated range, the charge needed and the additional charge after the large-capacity discharge are called the equalizing charge.
3.0.10 Terminal Battery
Batteries except the basic batteries in the storage battery.
3.0.11 Checking Discharge
To check the actual capacity of the storage battery under the normal operation, the constant current discharge is made at the stated discharging current. As long as the battery reaches the stated discharge finish voltage, the discharge will be stopped. Then, according to the discharging current and time, the actual capacity of the storage battery shall be calculated and called the checking discharge.
3.0.12 Finish Voltage
During the selection calculation of the accumulator capacity, the finish voltage refers to the power consumption load in the DC system. Within the stated discharge time, the battery shall keep the lowest discharge voltage. As far as the battery is concerned, the finish voltage refers to the permissible lowest discharge voltage within different discharge times and under different discharge conditions of different discharge ratios. Generally, the former is a little higher than the latter.
3.0.13 Electromagnetic Compatibility (EMC)
The capability of the equipment or system able to make them work normally under the electromagnetic environment and not generate unallowed electromagnetic interference in the environment. |
