火炬蓄电池3-DG-210（3-EV-180）是电动车专用蓄电池，6V210AH适用各种电动观光车、巡逻车、高尔夫球车、电瓶叉车、洗地车、电动环卫车、游览车等动力蓄电池。具备600次深循环能力，可持续工作5小时以上，寿命长，爬坡能力强。 电动观光车蓄电池在出厂时均经过了严格的组配，但众多的原因还是会导致串联蓄电池组的单格差异。要保持电动观光车蓄电池通气孔通畅，避免堵塞。因为电动观光车蓄电池在充放电过程中会产生氢气和氧气，特别是在电动观光车蓄电池过充电状态下，水被电解而产生大量的氢气和氧气，这些气体通过通气孔排出。电动观光车蓄电池加液孔盖上的通气孔就是用来散发这些气体的。如果通气孔堵塞，这些气体就会在电动观光车蓄电池内积聚，造成电动观光车蓄电池内部压力急剧升高，严重时还会导致电动观光车蓄电池爆炸。The torch battery 3-DG-210 (3-EV-180) is a special electric vehicle battery, 6V210AH is suitable for various electric sightseeing cars, patrol cars, golf carts, electric forklifts, washing cars, electric sanitation vehicles, tourist car battery. With 600 deep cycle capacity, sustainable work for more than 5 hours, long life, strong climbing ability. Battery electric sightseeing cars in the factory have to undergo a rigorous combination, but many reasons may lead to differences in single series storage battery. To maintain electric sightseeing car battery ventilation hole smooth, avoid blocking. Because the battery electric cars will produce hydrogen and oxygen in the process of charge and discharge, especially the overcharge state in the battery electric sightseeing cars, water electrolysis and produce large amounts of hydrogen and oxygen, the gas through the air vent. Vent electric sightseeing car battery cover on the liquid is used to distribute these gases. If the air hole is blocked, these gases will accumulate in the electric sightseeing car battery, resulting in the rapid increase of the battery pressure inside the electric sightseeing car, which will lead to the explosion of the battery.
When the torch battery is in use, the utility model is connected with a battery of the same type according to the specified quantity and a certain mode to be used in a battery pack.
The utility model is characterized in that the utility model is characterized in that the connection between the single battery and the battery pack is composed of two forms of bolt connection and welding connection
The connection between the thread and the external thread can be divided into two parts: the flexible wire welding and the lead welding.
The battery cell induced by electric sightseeing cars behind. These reasons are mainly:
(1) the individual differences of self discharge of battery electric sightseeing car caused by single backward.
(2) single difference exhaust pressure electric sightseeing car battery, the battery cell caused by backward.
(3) the difference of EV battery sulfuric acid density, caused by single backward.
(4) single difference electric sightseeing car battery water loss, causing the battery cell backward.
(5) electric sightseeing car battery cell manufacturing process difference caused by backward battery.
Method of preventing electric sightseeing car battery charging backward:
(1) if there are conditions, can be individually to each group of electric sightseeing car battery charging, that is, using parallel charging method for charging.
(2) the small current constant current charging, preferably using 0.03C~0.05C charging current, charging process in such a small current in the long time, high voltage electric sightseeing car battery charge capacity is not much, will gradually increase the charging voltage is low, then slowly close to balance.
火炬蓄电池在使用时，是由同一型号的电池按照规定数量和一定的方式连接成电池组来使用的。 诱发电动观光车蓄电池单格落后。这些原因主要有：  ?nid=489&lid=90
(1) 电动观光车蓄电池自放电的个体差异引起单格落后。
(2) 电动观光车蓄电池的排气压力存在单格差异，引起蓄电池单格落后。
(3) 电动观光车蓄电池硫酸液密度的差异，引起单格落后。
(4) 电动观光车蓄电池失水的单格差异，引起蓄电池单格落后。
(5)电动观光车蓄电池的单格制造工艺的差别，引起蓄电池落后。
电动观光车蓄电池单格落后的防止方法：
(1)如果有条件，可单独给每一组 电动观光车蓄电池单独充电，也就是采用并联充电的方法进行充电。
(2)采用小电流恒流充电，*好是采用0.03C~0.05C电流进行充电，在这样小电流长时间的充电过程中，达到高电压的电动观光车蓄电池充入电量不多，充电电压低的会逐步提升，随后会慢慢接近平衡。
