      <abstract xml:lang="ru">
        <p> Проблема энергетики вспышечной активности звезд-карликов в нижней части Главной последовательности диаграммы Герцшпрунга – Рассела актуальна в связи с обнаружением мощных вспышек (супервспышек) и возможностью оценки таких явлений на Солнце в прошлом и будущем. В статье приводится краткий исторический обзор оригинальных исследований EV Lac и описаны современные базы данных, содержащие информацию о фотометрических наблюдениях звезды. Основное внимание уделяется наблюдениям EV Lac обсерваторией TESS. 
 Приведены результаты анализа вспышечной активности звезды по данным проекта TESS. Продемонстрированы наиболее типичные вспышки. Исследована зависимость вспышечной активности EV Lac от фазы осевого вращения звезды. Проиллюстрирована зависимость числа вспышек от фазы и их энергии. Обозначен участок фазы кривой блеска EV Lac, содержащий вспышки с наибольшей энергией. </p>

        <p> The problem of energetics of flare activity of dwarf stars in the lower main sequence of the Hertzsprung-Russell diagram is relevant in the context of the detection of powerful flares (superflares) and the possibility of assessing such phenomena on the Sun in the past and in the future. A brief historical review of the EV Lac original researches is presented and modern databases containing information on photometric observations of the star are described. The main attention is paid to the observations of EV Lac made by the TESS observatory. 
 Results of the analysis of flare activity of the star according to the data of the TESS project are presented. The most typical flares have been demonstrated. The dependence of flare activity of EV Lac on the phase of its axial rotation has been studied. The dependence of the number of flares on the phase and their energy is illustrated. The segment of the phase of the EV Lac light curve, which contains flares with the highest energies, is indicated. </p>
