Abstract

The invention provides a pre-charging circuit fault diagnosis method, a device thereof and an MCU. When the pre-charging circuit starts to work, an initial voltage value of a battery pack and an initial current value of a resistor are acquired; after a preset period of time, the current current value of the resistor and the loaded current voltage value are obtained; and fault diagnosis is carriedout on the pre-charging circuit according to the initial voltage value, the initial current value, the current current value and the current voltage value, and whether pre-charging succeeds or not canbe known in time, and fault diagnosis on the pre-charging circuit is carried out in time to obtain possible faults of the pre-charging circuit when pre-charging fails, thereby facilitating maintenance of the pre-charging circuit.

Description

technical field [0001] The present application relates to the field of new energy vehicles, in particular, to a precharging circuit fault diagnosis method, device and MCU. Background technique [0002] With the development of technology, new energy vehicles or motorcycles are becoming more and more popular. When a new energy vehicle or motorcycle is working, it is necessary to load the system with high voltage. If the voltage of the load itself is low, the load may be damaged if the system is loaded with high voltage. [0003] The prior art proposes a pre-charging circuit through which the load can be pre-charged so that the voltage of the load is close to the high voltage of the system, thereby avoiding damage to the power supply circuit when the high voltage of the system is loaded. When the pre-charging circuit fails, it will lead to unsuccessful pre-charging. At this time, the pre-charging circuit needs to be repaired. For the maintenance of the pre-charging circuit,...
