文档介绍：长春理工大学本科设计 I 电动助力车快速充电站设计摘要: 针对电动车行驶距离短、充电时间长、补充点能慢等特点,设计一款专门用于电动车快速充电的智能快速充电站。我国的电动车用动力蓄电池大多为铅酸蓄电池,但常规的充电时间过长,快速充电技术至今仍未能完全解决,严重地制约着电动车的发展。基于此,本文结合电动车充电的实际要求,给出快速充电的整体方案,并就方案中的主电路,及单片机控制电路具体分析,提出一种可对铅酸蓄电池实现四段式慢脉冲充电的智能充电设计方案。控制开关电源的脉冲频率和占空比,从而调节充电电流和电压,实现对蓄电池的分级慢脉冲充电。这个方案不仅可实现快速充电,同时可以减少析气,消除硫化,进行均衡充电,从而大大地延长了铅酸蓄电池的使用寿命。关键词: 快速充电,单片机,分级慢脉冲,蓄电池长春理工大学本科设计 II An electric moped fast charging station design Abstract : For electric vehicles with short range and long charging time, added point can slow wait for a characteristic, design a special intelligent fast charging stations for electric vehicles quick charge. Most of China's electric vehicle power battery for lead-acid batteries, but the normal charging time is too long, fast charging technology has failed to pletely, seriously restricts the development of electric vehicles. Based on this, this bining the actual requirement of electric vehicle charging, rapid charging of overall scheme are given, and the scheme of the main circuit, single-chip puter control circuit and a detailed analysis, put forward a kind of can implement four-paragraph slow pulse charging of lead-acid battery intelligent charging design scheme. Control pulse frequency and duty ratio of switch power supply, so as to adjust the charging current and voltage, to realize hierarchical slow pulse charging of battery. This scheme not only can realize quick charge, can reduce the gas chromatography at the same time, eliminate sulphide, equalizing charge, thus greatly extend the service life of the lead-acid battery.
