Lead-acid battery is one of the 21st century green energy, since the battery was invented to be applied to all walks of life to their years, researchers have not given up on its performance from improvements and enhance research, while, in order to meet the new lead-acid batteries the charge requirements, charging technology innovations has never been stopped. In this paper, fast, secure, low cost and other factors into account, the proposed three-stage lead-acid battery fast charging methods, and associated with this rapid charging system is studied and implemented. Meanwhile, the paper established a groundbreaking real-time detection and feedback sensor lead-acid battery charging process temperature and internal pressure parameters, make up the traditional fast charging device handle fast charging performance impact factor deficiency. In the lead-acid battery fast charging system design, including the charging and discharging two main circuit and control circuit part. Charge and discharge the main circuit includes a pulse waveform generation and charge-discharge circuit implementation; control loop mainly refers to the microcontroller core, through the A / D real-time acquisition of lead-acid battery terminal voltage, the internal pressure and temperature information, and feedback to microcontroller for analysis and processing, to obtain the corresponding control signals to control the charge and discharge circuit of the MOS tube off and charge-discharge pulse waveform output, to achieve the lead-acid battery smart charger; and through the RS232 serial interface bus SCM and PC inter-point transmission, the sampling data monitoring and preservation. In the fast charge control technology, using a lead-acid battery terminal voltage control-oriented, temperature and internal pressure supplemented by a comprehensive control method for judging whether the full conditions. Finally, hardware circuit design, software programming and design and simulation platform, simulation results fast red charging control algorithm is feasible, and rapid charging system for the testing and validation. As the system is controllable, therefore, the charging system is not only able to complete the lower cost of the lead-acid battery of fast, safe, and healthy charging, the charging device can be used in lead-acid batteries of different sizes charging; while using a sensor sampling due to feedback, so this method can be applied to the battery manufacturers for the same volume, with the specifications of the battery charging parameters of the test experiments, and even can be extended to large-scale power battery charging.
