Description
Technical field the utility model relates to a kind of charging device of valve controlled sealed lead-acid accumulator, especially the luffing of valve controlled sealed lead-acid accumulator intelligence pulse charger.
Background technology is low because of valve controlled sealed lead-acid accumulator (VRLA) price, and easy the recovery so obtained using widely, disposed the storage battery of this type with regard to major part as current commercially available electric bicycle.But this storage battery has short deficiency in useful life, general only one year about.Through learning that to the research of accumulator charging/discharging process with to the valve controlled sealed lead-acid accumulator analysis of scrapping the main cause of its inefficacy has three kinds: the first is owing to undercharge, and positive/negative plate forms very thick white lead sulfate deposition; It two is prolonged and repeated overcharging or floating charge, and the storage battery dehydration is serious, and internal resistance increases and can't recharge; It three is to cause the battery performance deterioration because the internal resistance discreteness strengthens the voltage inconsistency that causes in many storage batterys series connection uses.The charge mode that to cause these three kinds of failure cause causes of valve controlled sealed lead-acid accumulator are charging devices is unreasonable.
Summary of the invention is at above-mentioned deficiency, technical problem to be solved in the utility model is exactly the charge mode that will change the charging device of valve controlled sealed lead-acid accumulator, cause the reason of battery malfunction with elimination, and a kind of charging device of valve controlled sealed lead-acid accumulator is provided.
