Charging notification arrangement in underground mining vehicle

An underground mining vehicle comprising:

• an electric motor for driving the vehicle;
• a rechargeable battery for supplying electric energy to the electric motor;
• a charging system including a charging circuit and a charging connection connected to the charging system for supplying electric energy to the charging system from an electric power source external to the vehicle for recharging the rechargeable battery;
• a battery cooling system including at least one cooling circuit having a cooling agent for cooling the battery;
• a measuring element for measuring cooling agent temperature in the at least one cooling circuit;
• a control unit configured to control an operation of the charging system for controlling the recharging of the battery, the control unit being configured to have a number of different, selectable recharging modes, wherein each selectable recharging mode has unique recharging parameters that affect at least one of a recharging voltage, a recharging current, a recharging power and a duration of the recharging, and to control the recharging of the battery according to the selected recharging mode, wherein the control unit is configured to perform an automatic change from one selectable recharging mode to another selectable recharging mode in response to the cooling agent temperature in the at least one cooling circuit exceeding an overheating limit;
• and
• a transmitter controlled by the control unit at least for sending a status notification about an automatic change from one selectable recharging mode to another selectable recharging mode to an operator remote terminal device of an operator of the underground mining vehicle.
