智能燃气表中复合电池的应用评价

Evaluation of hybrid battery for smart gas meter

随着市场需求的发展,要求智能燃气表可在-25^+55℃的条件下工作10年,但是锂亚硫酰氯电池自身钝化的缺点导致其不能满足智能燃气表放出大电流和长寿命工作的需求;复合电池由锂电池并联一个大电容组成,电池负责给电容充电而电容即可放出大电流,同时也克服了锂电池钝化的缺点。为了更好地在智能燃气表领域应用复合电池,首先分析了复合电池特点,最后总结出基于智能燃气表的复合电池的电性能、安全性能的评价方法。

With the development of market demand, smart gas meter requirements work between-25 ℃ and ＋ 55 ℃for more than 10 years. But the voltage delay of lithium batteries leads to that the smart gas meter can＇t release a large current and meet a long working life. The hybrid lithium battery consists of a large capacitors and a battery. The battery is responsible for charging the capacitor and the capacitor can release high current which can overcome the shortcomings of the voltage delay of lithium battery. In order to apply the hybrid battery to the smart gas meter better,the characteristics of hybrid battery were analyzed, and the evaluation method of electrical performance and security performance based on the smart gas meter was concluded.
