Abstract

A system for controlling high voltage devices. The system includes a battery, a DC-DC converter, and an electronic processor. The electronic processor is configured to, in response to determining a partial startup condition is met, operate the system in a partial system mode and perform a full shutdown of the system in response to a failure requiring a full shutdown. The electronic processor is configured to, in response to determining a full startup condition is met, operate the system in a full system mode and, in response to a failure occurring, determine whether the full shutdown or a partial shutdown is required. The electronic processor is configured to perform the full shutdown of the system in response to determining the full shutdown is required, and, in response to determining the partial shutdown is required, perform the partial shutdown and operate the system in the partial system mode.

Claims17

Dependent claims

A system for controlling high voltage devices, the system comprising:

a battery;
a DC-DC converter;
and
an electronic processor, the electronic processor configured to:
determine whether a full startup condition or a partial startup condition is met;
in response to determining that the partial startup condition is met,
operate the system in a partial system mode, wherein, in partial system mode, the battery does not provide power to a motor included in a vehicle, is not charged via regenerative braking, and is charged, discharged, or both via the DC-DC converter;
and
in response to a failure that requires a full shutdown occurring, perform a full shutdown of the system;
and
in response to determining that the full startup condition is met,
operate the system in a full system mode, wherein, in full system mode, the battery provides power to the motor, is charged via regenerative braking, and is charged, discharged, or both via the DC-DC converter;
and
in response to a failure occurring,
determine whether the full shutdown or a partial shutdown is required;
in response to determining that the full shutdown is required, perform the full shutdown of the system;
and
in response to determining that the partial shutdown is required, perform the partial shutdown and operate the system in the partial system mode.
