Description

technical field [0001] The invention relates to an intelligent storage battery management device, which is specifically applied to the intelligent charging of storage batteries and the monitoring and management of battery life for field disaster geological monitoring instruments. Background technique [0002] Ordinary field disaster geological monitoring instruments are powered by batteries. The particularity of field work makes the state of the batteries directly related to the performance of the instruments and the cost of testing. Therefore, how to ensure the long-term and stable power supply of the monitoring system is an extremely critical issue. This puts forward higher requirements for the charging method and life management of the battery. It is required to realize intelligent charging, power-off, and real-time Monitor the current life of the storage battery, so that the user of the instrument can grasp the use of the storage battery and improve the reliability of us...

AI Technical Summary

Problems solved by technology

[0003] However, existing storage battery charging equipment, including constant voltage charging and constant current charging, has a single charging mode and cannot control the charging voltage or charging current. For example, for constant voltage charging, the setting of the initial charging voltage is difficult. Important, if the initial voltage setting is too large or too small, the battery capacity and life will be reduced

Moreover, the existing battery chargers are less intelligent, unable to charge according to the different characteristics of specific batteries, have no battery maintenance function, and cannot dynamically display the charging voltage and current, and cannot understand the charging process and usage status of the battery. , after the battery is fully charged, it cannot automatically power off, which reduces the battery usage rate

Therefore, the existing battery charging equipment cannot meet the needs of field disaster geological monitoring

[0004] The battery life can be monitored by monitoring the battery capacity. The common method is to integrate the current and voltage during the charging and discharging process of the battery, but this method has a large error
