Embodiment

[0033] Such as Figure 1~3As shown, a vehicle battery-powered detection system disclosed in the present invention includes a main control MCU, and a current input signal detection circuit, a current output signal detection circuit and a battery detection circuit connected to the main control MCU. It mainly uses the STM32F103C8T6 single-chip microcomputer control chip as the main control MCU. The current input signal detection circuit and the current output signal detection circuit detect whether the vehicle battery is in the charging state or the power supply state, so that the battery detection circuit is activated by the main control MCU to detect the single cell in the battery, and through the independent detection of the single cell of the battery , which can feed back the state of the battery more efficiently, thereby protecting the battery and the vehicle.

[0034] In this embodiment, the battery detection circuit includes a plurality of voltage comparators 2 connected ...

Abstract

The invention discloses a vehicle battery power supply detection system which mainly solves the problem that an existing vehicle power supply detection system cannot achieve single battery cell detection of a battery pack. The detection system comprises a master control MCU, and a current input signal detection circuit, a current output signal detection circuit and a battery detection circuit which are connected with the master control MCU. The battery detection circuit comprises a plurality of voltage comparators connected to the two ends of each cell of a battery, a control circuit connected with the output ends of the voltage comparators, and a change-over switch connected with the control circuit and used for switching on and off between the battery and a load. The current input signal detection circuit and the current output signal detection circuit are arranged to detect whether the vehicle battery is in a charging state or a power supply state, so that the battery detection circuit is started to detect a single cell in the battery, and the state of the battery can be fed back more efficiently through independent detection of the single cell of the battery; therefore, the battery and the vehicle are protected.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle batteries, and in particular relates to a vehicle battery power supply detection system and detection method. Background technique [0002] At present, electric vehicles are generally regarded as an important means of transportation in the 21st century by scientists and industries all over the world due to their advantages of energy saving, zero pollution and high efficiency. Electric vehicles use unconventional vehicle fuels as power sources, or use conventional vehicle fuels, adopt new vehicle power devices, and integrate advanced technologies in vehicle power control and drive to form advanced technical principles, new technologies, and new technologies. A pure electric vehicle is a vehicle that uses a single battery as the energy storage power source. It uses the battery as the energy storage power source, supplies electric energy to the motor through the battery, and drives the motor...
