Abstract: An underground mining vehicle includes an electric motor for driving the vehicle and a rechargeable battery for supplying electric energy to the electric motor. A charging system is connected to an electric power source external to the vehicle for recharging the at least one rechargeable battery. A cooling system is connected to a cooling agent source external to the vehicle for cooling the rechargeable battery. At least one detection element for detecting the cooling system is connected to the external cooling agent source.
