Three important methods of battery detection Battery monitoring management is designed for measuring the operating conditions of the battery and the condition of detecting the battery itself. The battery monitoring is important as the following three methods: 1 of the whole group monitoring, 2 single-storage battery voltage monitoring, 3 storage battery Exhaust surveillance and monitoring. 1 The whole group monitoring: The whole set of battery monitoring is generally designed to measure the voltage, current and temperature of the battery pack, charging and discharging, especially according to the ambient temperature change to adjust the floating charge voltage of the battery pack.
Comparison Ok, the battery pack voltage is low to a lower limit when the battery is discharged. It is difficult to find the slow change of a single battery, including the aging battery itself, the accumulation effect of the single battery itself and the accumulation of single-battery consistency, if only one battery is deteriorated The signal of its voltage change will be sinkable by other 23 batteries. Battery-end voltage and battery pack bine voltage have nothing to do with battery capacity.
The whole group monitoring cannot monitor the actual capacity of the battery and battery pack, which cannot screen the aging battery. 2 Single-storage battery voltage monitoring: The purpose of battery monitoring standards announced by my country Post and Telecommunications Department in 1997 is to standardize battery monitoring products and technologies. Clear requirements in standards to monitor each single battery.
Most of the products used in telecommunications departments are based on the standard design and processing. After the development of standards, the telecom operation and maintenance department expects to monitor the equipment to play an important use, and the actual situation is in the floating state, the monitoring equipment can only find poor individual performance, and the floating voltage is exceeding battery. The difference monitoring of the small amplitude of the floating voltage, there is no way to deal with the performance, that is, the performance of the battery performance deteriorates, the battery capacity has fallen sharply, then if the battery floating voltage variation is not obvious, monitor The system will not issue a police.
Instead, it is found that the discharge voltage of a battery is warned when discharging. But it is generally too late. Conclusion: Practice confirms that the warning and prospective pre-directional performance of single-storage battery voltage is unable to accurately determine the internal resistance and capacity of the battery, and find the aging battery in time.
3 Battery internal resistance monitoring and monitoring: in USALBéR company represented battery monitoring equipment manufacturers launched a series of products for internal resistance detection of battery invested by DC discharge law in recent years. It is the quality of battery monitoring technology, namely the passive monitoring battery voltage to active precise test of the internal state and monitoring of the battery. Battery pack dynamic changes.
