火炬蓄電池在使用時，是由同一型號的電池按照規定數量和一定的方式連接成電池組來使用的。

單體電池組合成電池組時的連接，有螺栓連接和焊接連接兩種形式，其中螺栓連接可分為內

螺紋連接和外螺紋連接，焊接連接可分為軟線焊接和鉛連條焊接（又稱硬連接）。

誘發電動觀光車蓄電池單格落后。

(1) 電動觀光車蓄電池自放電的個體差異引起單格落后。

(2) 電動觀光車蓄電池的排氣壓力存在單格差異，引起蓄電池單格落后。

(3) 電動觀光車蓄電池硫酸液密度的差異，引起單格落后。

(4) 電動觀光車蓄電池失水的單格差異，引起蓄電池單格落后。

(5)電動觀光車蓄電池的單格制造工藝的差別，引起蓄電池落后。

電動觀光車蓄電池單格落后的防止方法：

(1)如果有條件，可單獨給每一組 電動觀光車蓄電池單獨充電，也就是采用并聯充電的方法進行充電。

(2)采用小電流恒流充電，好是采用0.03C~0.05C電流進行充電，在這樣小電流長時間的充電過程中，達到高電壓的電動觀光車蓄電池充入電量不多，充電電壓低的會逐步提升，隨后會慢慢接近平衡。

3-DG-180（3-EV-160）

火炬蓄電池3-DG-180（3-EV-160）是電動車專用蓄電池，6V180AH適用各種電動觀光車、高爾夫球車、電瓶叉車、洗地車、電動環衛車、游覽車等動力蓄電池。具備600次深循環能力，可持續工作5小時以上，壽命長，爬坡能力強。 電動觀光車蓄電池在出廠時均經過了嚴格的組配，但眾多的原因還是會導致串聯蓄電池組的單格差異。要保持電動觀光車蓄電池通氣孔通暢，避免堵塞。因為電動觀光車蓄電池在充放電過程中會產生氫氣和氧氣，特別是在電動觀光車蓄電池過充電狀態下，水被電解而產生大量的氫氣和氧氣，這些氣體通過通氣孔排出。電動觀光車蓄電池加液孔蓋上的通氣孔就是用來散發這些氣體的。如果通氣孔堵塞，這些氣體就會在電動觀光車蓄電池內積聚，造成電動觀光車蓄電池內部壓力急劇升高，嚴重時還會導致電動觀光車蓄電池爆炸

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.
