  "textContent": "Provided is a charging system (50) for an electrically driven operation machine, comprising a charger (51) which charges a battery (41) by using electrical 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) and the like are stopped, 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) exceeds a predetermined temperature (for example -2°C), or if the temperature of the battery is equal to or less than a predetermined temperature, the battery (14) is charged, resulting in the battery (41) being made to generate heat, and when the late night time frame is reached, starts charging the battery (41).",
