Mains smart charger for storage battery of diesel generator set and its control method

Abstract

The invention relates to a commercial smart charger for a storage battery of a diesel generator set and a control method thereof. Including the control module, the control module is based on the ATMEGA32 single-chip microcomputer, which is used to control the whole charger; the power supply module is used to provide electric energy for the whole charger; the power conversion main module is used to convert AC power into DC power for The battery of the diesel generator set is charged; the communication module is used to communicate with the upper computer; and the sensor detection module is used to detect the ambient temperature, the temperature of the battery of the diesel generator set, the charging current, the charging voltage and the mains voltage signal. The charger of the present invention can effectively prolong the service life of the storage battery, has wide adaptability to the input voltage range and frequency range, and can adapt to a wider range of ambient temperature and air humidity, and can intuitively display various parameters of the storage battery and commercial power, and The fault information can be sent to the management personnel for timely fault handling.

Description

technical field [0001] The invention relates to a commercial smart charger for a storage battery of a diesel generator set and a control method thereof. Background technique [0002] Diesel generator sets are used in various sectors of the national economy due to their high power, compact structure, and high reliability. [0003] At present, the commercial high-speed land-use diesel generator sets are all started by lead-acid batteries. The lead-acid batteries are discharged during the start-up process of the diesel generator set. During the operation of the diesel generator set, the charger of the diesel engine is the lead-acid battery for floating charge. In the diesel generator set as a backup power supply, the unit needs to be started quickly when the mains power fails. At present, the power supply in my country is stable, and the diesel generator set does not need to work in 95% of the time. In order to maintain the self-consumption of lead-acid battery power , The lead...
