Description
Technical field [0001] The invention relates to the field of UPS controllers, in particular to a UPS battery life control system. Background technique [0002] UPS is an uninterruptible power supply, which can connect the battery and mains to the host. When the mains is normally supplied, it is directly connected to the mains and the mains. When the mains cannot be supplied normally, the DC of the battery is converted to AC through the inverter circuit. The voltage is boosted by the transformer to supply power to the host, and the battery is charged through the rectifier when the mains is normally supplied. A transformer is generally set up in the UPS to boost the inverter voltage. The transformer will generate a lot of heat during the working process to increase the internal temperature of the UPS, which will lead to the problem of reduced battery performance and shortened service life. The existing technology generally uses The fan integrated inside the UPS dissipates heat, an...
