摘要： A catalyst temperature control apparatus includes: a calculation part calculating an amount of heat transfer obtained by adding together i) an amount of heat that transfers from a wall surface of a catalyst to exhaust based on an exhaust temperature, exhaust flow rate, and catalyst wall surface temperature of an upstream side of the catalyst, and ii) an amount of heat that transfers from the wall surface of the catalyst to the outside air around the catalyst based on the catalyst wall surface temperature, the outside air temperature, and a vehicle speed; and a heater control part causing a heater provided upstream of the catalyst to generate heat if an estimated catalyst wall surface temperature of the catalyst after a first predetermined time period, which has been estimated on the basis of the amount of heat transfer and the catalyst wall surface temperature, is lower than a threshold.

摘要： A charging system, a management terminal, a vehicle, a charging method, and a non-transitory computer-readable recording medium capable of vehicles to be properly operated are provided. The charging system controls a plurality of vehicles and at least one charger that supplies charging power to the plurality of vehicles. The charging system includes a setting section that sets, for the plurality of vehicles, a charging plan indicating charging start times and charging end times and a control section that controls charging of a battery of each of the plurality of vehicles based on the charging plan. Even when one of the plurality of vehicles and the charger are connected to each other in a period for which the charging plan is set, the control section does not perform charging with the charging power supplied from the charger when present time is within a charging stop period in the charging plan.
