A control system is programmed for monitoring the health and charge of batteries used to power a battery electric machine (BEM) or other heavy equipment and determining when maintenance, service, or replacement should be performed for the batteries as a function of data related to travel route segments over which the BEM or other heavy equipment is operated. The control system is programmed to receive historical information mapping the performance and energy consumption of a BEM or other heavy equipment, such as battery state-of-charge, power usage, battery state-of-health, and number of charge cycles for a battery supplying power to the BEM or other heavy equipment operating over a travel route segment, and instruct an operator to replace or perform maintenance on the batteries if the difference between present and historical performance exceeds a threshold level.
