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。

Torch Energy Co., Ltd. (State-owned 481 Factory) was founded in January 1944 and is a wholly-owned subsidiary of China Shipbuilding Heavy Industry Group Corporation. It is one of the earliest producers of lead-acid batteries in China. It is a high-tech enterprise. It is also one of the manufacturers of special batteries for JUN. It is a qualified supplier of CNPC. The company is mainly engaged in the development, design and production of lead-acid batteries for traction, fixed, electric vehicles and lithium-ion power batteries. It now has the ability to produce 6 million KVAh lead-acid batteries annually. The company has six wholly-owned subsidiaries, covering the production and sales of battery manufacturing equipment, shell, partition, connection line, box, etc., to help the development of "torch" batteries.



The company has a comprehensive laboratory approved by the National Laboratory Accreditation Committee, provincial enterprise technology center, Shandong Power Battery Engineering Technology Research Center and Zibo Battery Product Performance Testing Center of China Shipbuilding Industry, and has established a civil-military integrated quality management system. It has passed IS09001 quality system certification, occupational safety and health management system and environmental management successively. System certification.

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.
