Abstract

The predominant solution for charging lightweight EVs such as electric three-wheelers (ETW) and e-rickshaw has been a line frequency step-down transformer with rectifier due to its low cost and ease of use. This conventional charging system cannot regulate output voltage or current due to the lack of any feedback or sensing. Batteries charge inconsistency due to lack of control circuitry, resulting in overcharging, overheating, and, most significantly, energy waste and accelerated battery life degeneration over time. This paper presents the design, development, and transient response with performance analysis of a charging system based on high-frequency H-bridge DC-DC converter. The designed system has digital closed-loop control for individual regulation of output current & voltage while being small and lightweight. The charger allows batteries to be efficiently charged at preset voltage & current values depending on desired charging profile based on battery chemistry and SOC. A hardware prototype of 60V, 1.2kW is created for performance analysis and evaluation.

电网电压波动时轻型电动汽车连续充电的CC-CV集成充电器的瞬态响应

为轻型电动汽车(如电动三轮车和电动三轮车)充电的主要解决方案是带整流器的线频降压变压器，因为它成本低且易于使用。这种传统的充电系统不能调节输出电压或电流，由于缺乏任何反馈或传感。由于缺乏控制电路，电池充电不一致，导致过充电、过热，最重要的是，随着时间的推移，能源浪费和电池寿命加速退化。本文介绍了一种基于高频h桥DC-DC变换器的充电系统的设计、研制、暂态响应及性能分析。设计的系统具有数字闭环控制，可单独调节输出电流和电压，体积小，重量轻。充电器允许电池在预设的电压和电流值下有效充电，这取决于基于电池化学和SOC的所需充电配置文件。创建了60V, 1.2kW的硬件样机，用于性能分析和评估。
