Abstract

The invention discloses an ASIC photovoltaic MPPT battery pack charger, which utilizes an ASIC as a main control chip, and the main control chip ASIC comprises four different forms of adjustment: an output current, an input current, an input voltage and an output voltage. When powered by a solar cell panel, the MPPT function provided by the main control chip ASIC uses input voltage regulation to locate and track the maximum power point of the solar cell panel. The input current regulation is used for limiting the maximum current extracted from the input power supply to a safety level; the output current is adjusted to set the maximum charging current of the battery, and the output voltage is adjusted to set the maximum charging voltage of the battery. By means of the mode, the photovoltaicbattery pack charger which is low in cost, small in size and high in efficiency can be manufactured, the charging power of the battery pack is guaranteed to be stable in local cloudy days, and the photovoltaic utilization efficiency is improved.

Description

technical field [0001] The invention belongs to the fields of new energy technology and electronic technology, and in particular relates to an ASIC photovoltaic MPPT battery pack charger. Background technique [0002] MPPT, the abbreviation of Maximum Power Point Tracking, is "maximum power point tracking" in Chinese, which means that the photovoltaic charger adjusts the output power of the photovoltaic array according to the characteristics of different external ambient temperatures and light intensity, so that the photovoltaic array always outputs the maximum power. MPPT algorithm is a very core technology of photovoltaic chargers, and MPPT voltage is a very critical parameter in the design of photovoltaic power plants. However, in the prior art, when it is cloudy, the charging power of the battery pack is unstable, and the efficiency of photovoltaic utilization is low. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, an A...
