Tips for protecting golf cart batteries from the cold
Storage in the greenhouse: In order to prevent the battery of the four-wheeled electric golf cart from being cold, the battery must be stored in a room temperature above 0°C when not in use, and cannot be placed directly on the ground. Before storage, the outside of the golf cart battery should be cleaned first, and then the lithium manganate battery should be filled up. The battery should be fully charged, and then the oil plug should be tightened.
Lifting liquid volume preparation: Lithium manganate battery is composed of water and hydrochloric acid. The greater the content of hydrochloric acid in lithium manganate battery, the higher the proportion of lithium manganate battery, and the lower the freezing temperature of lithium manganate battery. Therefore, All parts of the country can choose the ratio of lithium manganese oxide battery that suits them according to the local lowest winter temperature, so as to avoid freezing of lithium manganese oxide battery. If the lithium manganate battery is frozen, it will also cause battery damage.
Environmental temperature of electrolysis method: The temperature of the battery electrolyte has an impact on the capacity of the four-wheeled electric golf cart battery. For every 1°C decrease in the storage operating temperature, the battery power will also decrease by about 1%-2%. Therefore, in order to increase the ambient temperature of the electrolytic solution of the four-wheeled electric golf cart, the four-wheeled electric golf cart should be placed in the room, and the battery should be moved into the room above 0°C.
Maintenance methods of electric golf carts
Do not store and discharge without electricity. The situation of electricity shortage refers to electric golf carts. The battery of the battery sightseeing car is not charged in time after use, and sulfation is easy to occur. Lead sulfate crystals adhere to the pole piece and block the calcium channel. , resulting in insufficient charging of the battery and a decrease in battery capacity. The longer the battery is idle without power, the more damage the battery will be. When the battery is not in use, the battery should be charged once a month, which can also increase the service life of the battery.
Regular inspection is required. In use, if the mileage of the electric golf cart suddenly drops by more than ten kilometers in a short period of time, it is likely that a rechargeable battery in the battery pack has broken, the pole piece has become soft, and the pole piece has become active. Short-circuit faults such as components falling off. At this time, it is necessary to go to a professional battery repair organization for inspection, repair or assembly in time.
Do not charge and discharge at high voltage, try to reduce the momentary high voltage charge and discharge. High-voltage charging and discharging are likely to cause lead sulfate crystals, which will endanger the process performance of battery pole pieces.
Grasp the charging time. Generally, the battery is charged at night, and the average charging time is more than 8-10 hours. If shallow charging and discharging, the golf cart battery will be full soon, and it will be prone to overcharging when recharging the battery, causing the battery to lack water, heat up, and shorten the battery life. Therefore, it is better to charge the battery once when the depth of discharge is 60%-70%. In actual application, it needs to be converted into cycling mileage, and the battery should be charged according to the actual situation to prevent harmful battery charging.
Avoid continuous high temperature exposure, and golf carts cannot be exposed to the sun. The living environment with too high temperature will increase the working pressure of the internal structure of the battery, so that the battery pressure relief valve has to be opened automatically, and the immediate result is to increase the water loss of the battery, and the excessive water shortage of the golf cart battery will definitely reduce the battery vitality and speed up. The pole piece becomes soft, and the shell becomes hot, bulged, deformed and other serious damages during charging.
