Abstract

The present disclosure relates to a system (200), method, control unit and computer program product for battery charge management of one or more battery operated mining machines (210a, 210b). The system for battery charge management comprises one or more batteries (220a-f), at least one battery management systems, BMSs (230a-f), arranged to gather battery data representative of an operating stateof a respective battery, one or more battery chargers (240a-b), and a battery charge control unit (250). Each battery is configured for use in a respective battery operated mining machine configured to operate in a predetermined mining cycle and each BMS is configured to provide the battery data to the battery charge control unit. The battery charge control unit is configured to generate at leastone charge model based on the battery data and to schedule charging of respective batteries of the one or more batteries via the one or more battery chargers based on the at least one charge model.

Description

technical field [0001] The present disclosure relates to systems, methods, control units and computer program products for battery charge management of one or more battery powered mining machines. Background technique [0002] Work is underway to adapt mining machines to operate on electric power, and more specifically, to operate at least partially in a battery-powered mode. In addition to mining machinery, there are other electrically driven devices such as ventilation fans, cranes, lighting, etc. These other devices may also be at least partially battery powered. Switching from fuel driven machinery (and devices) to electric drive and battery powered machinery increases the electrical energy consumption in the mine, and the charging of the batteries will have a significant impact on the electrical consumption in the mine. Conventional battery charging solutions for mine applications disclose the use of battery management systems / energy management systems (BMS / EMS) for o...
