Suspended battery drivetrain as an example of advanced control and safety system of li-ion battery pack technology in mining industry

Description of special design of large 160kWh battery pack with its unique advanced battery management and thermal management system destined for suspended drivetrain for coal mine operation is presented in this paper. Battery has to be designed to meet strict rules and standards of mining industry and fit into antiexplosion tight enclosure without possibilities of liquid cooling circuits. A special active cooling based on Peltier heat pumps has been designed and implemented. Together with battery a special underground charging station has been design with additional safety circuits allowing additional redundancy of supervision during charging process.
