CHARGING SYSTEM FOR OPERATION MACHINE

WIPO Patent Application WO/2011/093037

A1

A charging system (50) for an electrically driven operation machine comprises a charger (51) which charges a battery (41) by using electric power supplied from an outside commercial power supply (55), a charging control section (52) which controls the operation of the charger (51), and a thermometer (53) which measures the temperature of the battery (41). When the operations of a pump-driving electric motor (33) etc. are at a stop, the charging control section (52) controls the operation of the charger (51) in such a way that outside of a late night time frame, the charging of the battery (41) is stopped if the temperature of the battery (41) is in excess of a predetermined temperature (-2OC for example), or the battery (41) is charged, resulting in the battery (41) being made to generate heat, if the temperature of the battery (41) is not higher than the predetermined temperature, and that when the late night time frame is reached, the charging of the battery (41) is started.
