An apparatus comprises a first energy storage device (12, 100) configured to output a DC voltage, a first bi-directional voltage modification assembly (14, 102, 104, 106) coupled to the first energy storage device (12, 100), and a charge bus (16) coupled to the first energy storage device (12, 100) and to the first bi-directional voltage modification assembly (14, 102, 104, 106). The apparatus also comprises high-impedance voltage source (62) coupleable to the charge bus (16) and a controller (56) configured to monitor a transfer of charging energy supplied from the high-impedance voltage source (62) to the first energy storage device (12, 100). The controller (56) is also configured to compare the monitored transfer of charging energy with a threshold value and, after the threshold value has been crossed, control the first bi-directional voltage modification assembly (14, 102, 104, 106) to modify one of a voltage and a current of the charging energy supplied to the first energy storage device (12, 100). |
