Golf cart battery according to its exhaust mode is divided into exhaust type and valve control type two. Implementation standard: GB/T 32620.1-2006. There are significant differences in the structure and maintenance of the two batteries. Exhaust batteries are rich liquid batteries. Water refill is required during use. The valve-controlled battery is maintenance-free, and no water refill is required during use. In the valve-controlled battery charging process, the gas generated by electrolytic water is regenerated by oxygen recombination reaction, so as to realize the battery in use without water refill. However, because the valve-controlled battery is designed for lean liquid, it is more sensitive to temperature in the process of use, and the battery is prone to thermal runaway swelling, which leads to battery failure.

The necessity of replenishing golf battery:

Golf batteries are exhaust rich liquid batteries. After a period of use, the electrolyte inside the battery will gradually decrease with the evaporation of water vapor during use and the electrolytic water reaction during charging. When the liquid level is lower than the height of the plate inside the battery, the plate will be exposed to air and oxygen in the air contact resulting in plate oxidation, which will greatly reduce the discharge performance of the plate. At the same time, after the electrolyte is reduced, the proportion of sulfuric acid inside the battery will be high, and too high proportion of sulfuric acid will aggravate the corrosion of pole and plate grid, and shorten the service life of the battery. So the golf DT battery must be regularly added water.

Golf battery refill method:

Manual water refill: When adding water, open all the liquid hole plugs on the battery and add water one by one. It takes a long time to add water and the level of the liquid level is uneven after water is added. Uneven liquid level will cause the proportion of sulfuric acid in the battery to be inconsistent, which will directly affect the discharge performance and service life of the battery. Batteries are installed under the seat of the vehicle or in other hidden locations, making it more difficult to add water.

Automatic water refill: Golf automatic water refill system is that pure water will enter into each battery automatically after the water inlet pipe is connected. As the liquid level rises, the float will be jacked up. At the same time, the water injection port will be blocked until the buoyancy pushes up to the top and the liquid injection port will be closed, so as to achieve the purpose of automatic water addition. The automatic water adding system uses water pipes to connect all batteries in series, and water inlet ports are provided at easily accessible locations. During water refill, you only need to connect the water inlet ports to the water supply system. There is no need to expose batteries or unplug liquid holes one by one.

Intelligent water adding system for battery is an automatic water replenishing device developed for liquid rich battery, which can comprehensively replace manual water adding maintenance operation of battery, real-time monitoring of battery water shortage status, automatic water replenishing, induction stop when full of water, after installation, the electrolyte level can be kept in a healthy state throughout the whole process to ensure stable and balanced characteristics of battery electrolyte and optimize the use efficiency of battery equipment. Prolong the battery life.
