诱发电动观光车蓄电池单格落后。

(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。

3-DG-180（3-EV-160）

火炬蓄电池3-DG-180（3-EV-160）是电动车专用蓄电池，6V180AH适用各种电动观光车、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

Torch batteries are used by connecting the same type of batteries into batteries in a specified number and manner.

There are bolt connection and welding connection when single battery is assembled into battery pack. The bolt connection can be divided into two parts.

Thread connection and external thread connection, welding connection can be divided into soft wire welding and lead bar welding (also known as hard connection).

Induce electric sightseeing car battery lag behind.

(1) Individual differences in self-discharge of batteries in electric sightseeing vehicles result in backwardness of single cell.

(2) There is a single cell difference in the exhaust pressure of the storage battery of the electric sightseeing vehicle, which causes the lagging of the single cell of the storage battery.

(3) The difference of sulfuric acid density of batteries in electric sightseeing vehicles causes the lagging of single cell.

(4) The single cell difference of water loss of storage battery in electric sightseeing vehicle causes the single cell lagging behind.

(5) The difference of battery cell manufacturing technology of electric sightseeing vehicle causes the battery lagging behind.

Preventive methods for lagging battery cells of electric sightseeing vehicles:

(1) If conditions permit, the batteries of each group of electric sightseeing vehicles can be charged separately, i.e. in parallel.

(2) Low current constant current charging is better than 0.03C~0.05C current charging. In such a long time charging process with low current, the charging capacity of batteries for high voltage electric sightseeing vehicles is not enough, and the charging voltage will gradually increase, and then it will gradually approach the balance.




3-DG-180 (3-EV-160)

Torch battery 3-DG-180 (3-EV-160) is a special battery for electric vehicles. 6V180AH is suitable for all kinds of electric sightseeing cars, patrol cars, golf carts, battery forklift trucks, floor washers, electric sanitation vehicles, touring cars and other power batteries. It has 600 times deep circulation ability, can work for more than 5 hours, long life and strong climbing ability. The batteries of electric sightseeing vehicles have undergone rigorous allocation when they leave the factory, but many reasons still lead to the single cell difference of series batteries. To keep the battery vent of the electric sightseeing car unobstructed and avoid blockage. Because the battery of electric sightseeing car will produce hydrogen and oxygen in the process of charging and discharging, especially when the battery of electric sightseeing car is overcharged, water is electrolyzed to produce a large amount of hydrogen and oxygen, which are discharged through the ventilation hole. The air vents on the cover of the charging holes of the batteries of electric sightseeing vehicles are used to emit these gases. If the air vent is blocked, these gases will accumulate in the battery of the electric sightseeing vehicle, which will cause the internal pressure of the battery of the electric sightseeing vehicle to rise sharply, and even cause the battery explosion of the electric sightseeing vehicle in serious cases.
