Intelligent charging system and working method thereof

Abstract

The invention relates to the field of intelligent charging, and particularly discloses an intelligent charging system and a working method thereof, which extract correlation characteristics among charging data such as voltage, current, temperature, pressure and the like of a battery monomer which are acquired in real time through a characteristic encoder, and meanwhile, store the correlation characteristics among the charging data, such as the voltage, the current, the temperature, the pressure and the like, of the battery monomer. In addition, a convolutional neural network model based on a deep learning technology is adopted to mine high-dimensional implicit features of the electrolyte surface image, and a Gaussian density map is applied to fuse the charging feature vector and the surface feature vector, so that the classification result is more accurate. Therefore, a more accurate control type of the charging current can be obtained to judge whether the charging current needs to be increased, decreased or maintained, so that the charging effect can be better.

Description

technical field [0001] The present invention relates to the field of intelligent charging, and more specifically, relates to an intelligent charging system and a working method thereof. Background technique [0002] Due to economic development and social needs, electric bicycles have developed rapidly and become the main means of transportation. The electric bicycle charger is a device for charging the battery of the electric bicycle. It realizes the conversion of the mains power into the direct current for charging the battery. The quality of its design is directly related to the service life of the battery. Generally speaking, the electric bicycle charging device is the most critical and important component of the electric bicycle. [0003] At present, the lead-acid batteries used in electric bicycles are almost all valve-regulated sealed lead-acid batteries. VRLA battery is a kind of lead-acid battery developed forward, it overcomes the disadvantages of regular water ad...

VRLA battery is a kind of lead-acid battery developed forward, it overcomes the disadvantages of regular water addition and troublesome maintenance of traditional open lead-acid battery

However, in actual situations, there will be electrolysis of water, especially in the later stage of the charging process. When the lead sulfate reaction in the battery is about to end, if the charging continues, water will be electrolyzed, and oxygen will be released from the positive electrode, and oxygen will be released from the negative electrode. Hydrogen gas is released and bubbling occurs
