摘要： A charging device includes: a connection portion; charging means; and control means. A first type battery pack and a second type battery pack are connectable to the connection portion. The first type battery pack is configured to control charging itself to determine whether charging is feasible. The second type battery pack is configured to provide information to the charging device for determining whether charging is feasible and controlling a charging operation. The charging means supplies charging current to a secondary battery included in a battery pack connected to the connection portion. The control means is configured to control a charging condition based on a type of the battery pack connected to the connection portion.

摘要： In a cleaning machine provided with a main body which discharges cleaning liquid by a pump and a cleaning gun which is connected to the main body, the cleaning machine has: an electric motor which receives electric power supply from a battery pack and which drives the pump; and a control circuit which changes a rotating speed of the electric motor so as to increase/decrease the discharging pressure of the cleaning liquid. When the voltage of the battery pack is decreased down to a predetermined second voltage higher than a predetermined first voltage at which the electric power supply to the electric motor is stopped, the largest discharging pressure of the cleaning liquid is decreased to be lower than a current-state discharging pressure thereof.

摘要： A rechargeable system includes: a charger (4); a battery pack (1); an adapter (3) configured to be electrically connected between the charger (4) and the battery pack (1), a cable (58) configured to be electrically connected between the battery pack (1) and the adapter. A battery-side microcomputer (526) controls the shutdown circuit (523) such that the shutdown circuit (523) disconnects the at least one of the positive terminal (5a) of the battery pack and the negative terminal (5b) of the battery pack (1) from the rechargeable battery (51) when detection of the battery-side microcomputer (526) indicates occurrence of at least one of two following events: one event is such that the rechargeable battery (51) is fully charged. Another event is such that the rechargeable battery (51) has some errors.
