Abstract: A charger control apparatus includes a total current acquisition unit and a setting unit to control a plurality of chargers connected in parallel with each other and supplied with a current from a common wiring line. An upper limit value of a current flowing through the wiring line is described as a first upper limit value. The total current acquisition unit acquires a total value of a current flowing through the plurality of chargers. The setting unit sets, for each of the plurality of chargers, a second upper limit value being an upper limit value of a current flowing through the charger by using the first upper limit value. When a difference between the total value and the first upper limit value satisfies a reference, the setting unit updates the second upper limit value for each of the plurality of chargers by distributing the difference according to a first rule.

Abstract: The present disclosure suppresses a spread of a fire occurring outside an outdoor unit of a refrigeration apparatus to a board in an electric component box and suppresses reduction of a cooling function of a heat sink mounted to the board due to a measure against the fire spread to the board.

The support piece (41g, 41h, 41i) is formed such that an area in a top view of a portion of the support piece (41g, 41h, 41i) positioned directly below the heat sink (51) is less than 10% of an area in the top view of the heat sink (51).
