New energy vehicle battery state remote monitoring method

Abstract

The invention discloses a new energy vehicle battery state remote monitoring method, comprising the following steps of: initializing battery state monitoring, judging whether the ON position of an ignition switch is on; when the ON position of the ignition switch is on, sampling and recording the voltage before the ON position is on, the instantaneous voltage of a battery when the ON position is on, and the voltage of the battery after the ON position is on; when the ON position of the ignition switch is off, sampling and recording the voltage of the single battery after the OFF position of the ignition switch is stabilized; judging whether the voltage of the single battery recorded in step 2 is greater than the conventional value, if not, going to step 2, or otherwise going to step 4; repairing the battery, after the repair, detecting the terminal voltage of the battery again; and repairing the battery, and after the repair, detecting the battery capacity of the battery again, if thebattery capacity is greater than the nominal value, completing online maintenance, or otherwise, discarding the single battery.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to a method for remotely monitoring the battery status of new energy vehicles. Background technique [0002] With the increasing popularization and widespread use of automobiles, the comfort, convenience and safety of automobiles have become more and more concerned by users. The automatic start-up of comfort equipment in the car puts forward an urgent demand for real-time monitoring of battery power. At the same time, as customers have higher and higher expectations for vehicle quality, and the number of vehicles increases, urban traffic jams and other situations often occur. Users also hope to have on-board equipment to monitor the capacity and life of the battery and give an early warning under certain circumstances. . [0003] For most of the vehicles currently on the market, the balance of the power supply system is matched in advance according to the p...

Problems solved by technology

[0003] For most of the vehicles currently on the market, the balance of the power supply system is matched in advance according to the power consumption of the equipment on the vehicle, the power generation capacity of the generator, the preset common working conditions and the overall capacity of the battery. Overall balance, in order to prevent the occurrence of special circumstances, generally a certain margin will be left, resulting in a certain amount of waste

At the same time, in some extreme situations, such as bad weather and long-term traffic jams, it will destroy the overall electrical balance, making it difficult to restart the vehicle after the engine is turned off, and even damage the battery, bringing unnecessary safety risks and economic losses to users.
