ISOLATED BATTERY MANAGEMENT SYSTEMS AND METHODS THEREOF |
摘要 |
Systems and methods of the invention relate to circuitry that isolates low power circuitry of a battery management system. One or more circuits can be utilized with a battery management system to provide isolation of low power circuitry from at least one of a high voltage, noise interference from a battery, noise interference from a high voltage, sensor signals, control signals, among others. The circuitry further provides high voltage from a grid to be stepped-down to a voltage level usable by circuitry, port(s), and/or a processor. |

1. A system, comprising:
a first circuit configured to convert a first voltage of a DC bus to a lower second voltage and isolate the second voltage from the first voltage; a processor; and at least one of the following:
a third circuit operatively connected to an output of the first circuit and configured to convert the second voltage to a lower fourth voltage, isolate the fourth voltage from the second voltage, and condition at least a first monitoring signal related to a battery module to form a first conditioned monitoring signal, wherein at least a signal conditioning portion of the third circuit is powered by the fourth voltage; ora fourth circuit operatively connected to the output of the first circuit and configured to convert the second voltage to a lower fifth voltage, isolate the fifth voltage from the second voltage, and condition at least a second monitoring signal related to the battery module to form a second conditioned monitoring signal, wherein at least a signal conditioning portion of the fourth circuit is powered by the fifth voltage; wherein the processor is configured to receive at least the first conditioned monitoring signal or the second conditioned monitoring signal. |
