Design of Active Equalization Circuit and Management System for Lead-Acid Batteries
摘要
對於市面上高功率應用，如電動摩托車，利用電池串聯的方法來提供所需的電壓是相當普遍的。48V之電動摩托車為四顆鉛酸蓄電池串連而成。鉛酸電池在經過幾次充電與放電下，電壓通常會產生不平衡之情形。如果沒有適當的保護，可能會導致鉛酸蓄電池因為過度放電而提早損壞。因此，鉛酸電池串聯上需要一個簡單的平衡電路，以改善電池的壽命，以避免過電壓或欠電壓情況發生。能量平衡電路，以提高鉛酸電池模塊匹配的問題，使鉛酸電池的安全性和循環壽命提高。本研究擬完成的鉛酸電池平衡電路設計。 本文提出了一種主動式均衡電路使串聯連接的電池電壓均衡電路。此系統空間上並不大，並沒有佔空間的問題，可以讓使用者方便攜帶與安裝，此外，為了使系統更加完整。除了電池平衡上設計，另外還提到RLC電路上的改善、電壓估測手段、電池電壓通訊以及其他功能。最後一一驗證電路工作實現以及改善。

For high-power applications such as electric scooter, batteries in series to provide the required voltage is fairly common. The 48V is 12V connected four cells in series for lead-acid batteries of electric scooter. After charging and discharging of lead-acid batteries several times, the voltages are often imbalance. Without proper protection, may cause an excessive discharge of lead-acid batteries for early damage. Therefore, lead-acid battery module requires a simple balance circuit to improve battery life in order to avoid over-voltage or under-voltage condition occurs. Energy balance circuit to improve lead-acid battery module matching problems, make the safety and cycle life of lead-acid batteries to improve. This research intends to complete balanced circuit design of lead-acid batteries. This paper proposes a new active Equalization Circuit for voltage equalization in series connected battery cells. This system is the space is not great and there is no space problems, and allows users to install and easy to carry. In addition, Order for the system more complete. In addition to the battery balanced design, Improve the RLC circuit, voltage estimation methods, battery voltage communications and other functions. Finally, Verify circuit implementation and improvement.
