FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering, namely to a device for safe charging of accumulator batteries. Charging unit and storage battery are placed in sealed container with dielectric liquid, where temperature control means are installed, made in the form of thermal modules with maintenance of liquid temperature in the range specified on the control unit, as well as temperature and pressure sensors connected to the control unit, which supports automatic control of operating modes of the charging unit and the state of charge of accumulator batteries. Dielectric liquid temperature set on control unit is maintained by thermal module made in the form of Peltier element, and selection of fluoroketones as dielectric liquid provides electric and fire safety of accumulator batteries charging.
EFFECT: increased safety of accumulator batteries charging by control over condition of cooling liquid.
