    摘要: A battery management apparatus includes an SOC calculation unit to calculate an SOC of a battery module by using at least one of voltage, current, or temperature measured for the battery module in which a plurality of battery cells are connected in parallel, an SOH calculation unit to calculate an SOH of the battery module based on at least one of the SOC calculated by the SOC calculation unit and the voltage, current, or temperature of the battery module, and a diagnosis unit to calculate a change rate of an SOH using the SOH, and diagnose a state of the battery module using the calculated SOH change rate. The state of the battery module is any one of a normal state, a state including a degenerate battery cell, or a state including a current interrupt device (CID) open battery cell.

    摘要: 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.

    摘要: A measurement system for determining a status of a high-voltage power system in a vehicle, the measurement system comprising: a first voltage measurement unit and a second voltage measurement unit, each of the first and second voltage measurement units being connected between a positive pole and a negative pole of the power system; a measurement system control unit connected to the first and second voltage measurement unit and configured to: control the first and second voltage measurement unit to simultaneously measure a voltage to determine a respective first and second pole-to-pole voltage; compare the first pole-to-pole voltage with the second pole-to-pole voltage, and if a voltage difference is higher than a voltage threshold value, provide an indication that the voltage measurement is not reliable.
