Title:
VOLTAGE CONVERSION MODULE
Document Type and Number:
Japanese Patent JP2023072910
Kind Code:
A
Abstract:
To make it possible to, in the occurrence of an abnormality in one of two DC-DC converters, use the entire power of a battery with the other DC-DC converter.SOLUTION: A voltage conversion module includes a first battery, a second battery, an intermediate wire connecting between a negative electrode of the first battery and a positive electrode of the second battery, an auxiliary machine, a first DC-DC converter that converts voltage between a positive electrode of the first battery and a negative electrode of the second battery, a second DC-DC converter that converts voltage between a first input terminal and a second input terminal, a first switch provided between the positive electrode of the first battery and the first input terminal, a second switch provided between the intermediate wire and the first input terminal, a third switch provided between the intermediate wire and the second input terminal, and a fourth switch provided between the negative electrode of the second battery and the second input terminal.SELECTED DRAWING: Figure 1
