Systems and methods for voltage-based current limiting

Abstract

A system and method of controlling voltage in a power system by automatically manipulating current with a power conversion device (204) in response to a measured voltage value within the power system meeting or exceeding at least one predetermined threshold. The power conversion device (204) may also automatically disconnect from the power system when the measured voltage value meets or exceeds an over-voltage protection threshold. Current manipulation and disconnect from the power system may occur without receiving a command from a supervisory controller (206). 20 26 20 17 59 09 M ar 2 02 6 0 9 M a r 2 0 2 6 2 0 2 6 2 0 1 7 5 9 Charge Controller Powertrain System Differential Transmission Motor I / O Battery Management Unit Powertrain Controller Subsystem(s) Reporting Accessory 110 113 115 112 135 132 166 115 164140 115 150 122 168 120 114 115 162 100 160 134 1 / 41 / 4 134 160 100 113 115 Motor 115 Differential 114 Transmission 112 135 120 I / O 132 122 168 150 115 Powertrain Controller 115 140 164 FIG. 1 20 26 20 17 59 09 M ar 2 02 6 1 / 4 2 0 2 6 2 0 2 6 2 0 1 7 5 9 0 9 M a r 1 1 0 1 0 0 1 1 5 M o t o r 1 1 5 1 1 4 T r a n s m i s s i o n 1 1 2 1 3 5 1 2 0 1 3 2 1 2 2 1 6 6 1 6 8 1 5 0 1 1 5 P o w e r t r a i n C o n t r o l l e r 1 1 5 1 4 0 1 6 4 F I G . 1
