Problems solved by technology
Mine power supplies are widely used. At present, most mining equipment uses lead-acid battery mine power supplies. When mine lead-acid batteries are used, they will produce hydrogen gas, which is an explosive gas. In the environment where the explosion risk rate is extremely high in mines Extremely unsafe; in addition, mining lead-acid batteries are large in size, small in capacity, heavy, and inconvenient to transport and place; and mining lead-acid batteries have short service life, low activity, and poor low-temperature performance, which greatly affect the use of mining lead-acid batteries The environment and conditions of use bring many uncertainties to the use of mining equipment, resulting in losses

The invention discloses a mining explosion-proof type lithium ion storage battery power supply. The power supply comprises a lithium ion battery module, a battery management system, a charging relay,a discharging relay and a DC / DC converter. The positive electrode of the lithium ion battery module is connected with the charging interface through a main contact of the charging relay. The positiveelectrode of the lithium ion battery module is connected with the discharge interface through the main contact of the discharge relay. The battery management system is respectively connected with coilanodes and cathodes of the charging relay and the discharging relay. A main contact of the charging relay and a main contact of the discharging relay are respectively controlled to be opened and closed. The positive input end of the DC / DC converter is connected with the positive electrode of the lithium ion battery module, the positive output end and the negative output end of the DC / DC converterare connected with the battery management system, and the negative electrode of the lithium ion battery module and the negative input end of the DC / DC converter are connected with the total negativeelectrode of the vehicle. The mining explosion-proof lithium ion storage battery power supply does not generate harmful combustible gas in the use process, and is safe to use.
Description
technical field [0001] The invention relates to a mining power supply, in particular to a mining explosion-proof lithium-ion storage battery power supply. Background technique [0002] At present, with the improvement of coal mining technology level, my country's large mining height fully mechanized caving face has developed rapidly. Mine power supplies are widely used. At present, most mining equipment uses lead-acid battery mine power supplies. When mine lead-acid batteries are used, they will produce hydrogen gas, which is an explosive gas. In the environment where the explosion risk rate is extremely high in mines Extremely unsafe; in addition, mining lead-acid batteries are large in size, small in capacity, heavy, and inconvenient to transport and place; and mining lead-acid batteries have short service life, low activity, and poor low-temperature performance, which greatly affect the use of mining lead-acid batteries The environment and conditions of use bring many un...
