Problem of Reduced Driving Range
Difficulty: As the usage time increases, the driving range of the lithium battery gradually decreases, making it difficult to meet the daily operation requirements of the golf cart. This is mainly because the active substances inside the battery gradually wear out, and the structure of the electrode materials changes, leading to a reduction in battery capacity. In addition, frequent deep charging and discharging, as well as use in high or low temperature environments, will accelerate the degradation of battery performance. For example, in the hot summer, when the temperature on the golf course is too high, the chemical reaction speed of the lithium battery accelerates, the internal impedance increases, and the driving range is significantly shortened. In the cold winter, the fluidity of the electrolyte deteriorates, the ion diffusion speed slows down, and the available capacity of the battery drops substantially.
Solution Process: Firstly, optimize the usage habits and avoid excessive discharging and prolonged overcharging. It is recommended to charge the battery when the remaining power is around 20% - 30%, and unplug the charger in a timely manner after it is fully charged to prevent damage to the battery caused by overcharging. Secondly, improve the usage environment of the battery. Equip the golf cart with a sunshade to avoid exposing the battery to direct sunlight in high temperatures. In cold weather, try to park the cart indoors or in a place with a relatively high temperature, or install a thermal insulation device for the battery. At the same time, conduct deep charging and discharging maintenance on the battery regularly. Perform a complete charge and discharge 1 - 2 times a month to activate the active substances inside the battery and restore part of the battery capacity. In addition, battery repair technology can be adopted. Utilize professional battery repair equipment, and through specific charging and discharging procedures and pulse repair technology, repair the battery, improve its charging and discharging performance, and extend the battery's service life.
