Lithium Ion Golf Cart Batteries VS Lead-acid Battery

Golf is a sport that many people yearn for and fascinate. On the golf course, everyone, every movement, every grass, and every air molecule are very pleasing to the eye. Every action is required to be perfect on this sports field, including driving a golf cart.

Golf carts, also known as tour buses, patrol cars, and electric off-road vehicles, are environmentally friendly passenger vehicles designed and developed for golf courses. With the battery as the traction force, this type of car has a long design life and sufficient power to climb hills.

Kinds of Golf Cart Batteries

Golf carts have different functions in different scenes. Golf carts can also be used in resorts, villa areas, garden-style hotels, tourist attractions, etc.From golf courses, villas, hotels, schools to private users, they will all be short-distance transportation. Because they have different functions in different scenarios, their configurations will be different. As more and more people take advantage of its versatile performance, the golf cart market is developing. The batteries used in golf carts are generally divided into three types, namely maintenance-free lead-acid batteries, water-added lead-acid batteries that need to be maintained, and lithium batteries.These batteries have their own advantages.

Lead-acid maintenance-free battery

The biggest advantage of lead-acid maintenance-free batteries is that they do not require maintenance, as long as they are charged regularly in accordance with the usage regulations. Save time and effort, but also save maintenance costs. As long as the circuit is checked regularly during use and not used violently, the service life of maintenance-free lead-acid batteries is still considerable.

Lead-acid battery with water

Adding water to lead-acid batteries is relatively troublesome to maintain, and you need to pay attention to the amount of distilled water in the battery from time to time. If you do not add water in time, it will easily cause the battery to dry out and cause damage to the battery. Therefore, the battery condition needs to be checked regularly in daily use. In some scenic spots with slightly higher slopes, lead-acid batteries with water are more powerful, which is its advantage.

Lithium Battery

Lithium batteries are very simple. There are many advantages and one disadvantage. Compared with the other two types of batteries, the price has no advantage.

Golf Cart Battey: Lithium ion Battery VS Lead-acid Battery

For decades, deep-cycle submerged lead-acid batteries have been the most cost-effective means of powering electric golf carts. But with the rise of lithium batteries in many high-power applications, many people are now studying the advantages of lithium batteries. Generally speaking, golf cart batteries are mainly divided into lithium batteries and lead-acid batteries. Next, let’s analyze the difference between lithium batteries and lead-acid batteries in detail.

Carrying capacity

Loading lithium batteries into a golf cart can significantly increase the weight/performance ratio of the car. The volume of lithium golf cart batteries is half that of traditional lead-acid batteries, but the weight of lead-acid batteries is reduced by two-thirds of the normal use of golf carts. The lighter weight means that the golf cart can reach higher speeds with less effort and carry more weight without feeling sluggish.

The difference in weight and performance allows the lithium-powered stroller to carry two adults of average height and their equipment before reaching its carrying capacity. Since the lithium battery maintains the same voltage output regardless of how the battery is charged, the trolley continues to run after its lead-acid battery lags behind the battery pack. In contrast, lead-acid and absorbent glass felt (AGM) batteries will lose voltage output and performance after using 70% to 75% of the rated battery capacity, which will have a negative impact on the carrying capacity and become more complicated over time.

Battery charging speed

Whether you use lead-acid batteries or lithium-ion batteries, any electric car or golf cart faces the same defect: it must be charged.

A good golf cart needs to maintain consistent strength and speed on any course terrain. Lithium-ion batteries can solve this problem without problems, but lead-acid batteries will reduce the speed of the trolley when the voltage drops. In addition, after the power is dissipated, it takes about eight hours for an ordinary lead-acid battery to be fully charged. The lithium-ion golf cart battery can be charged to 80% of its capacity in about an hour and fully charged in less than three hours.

In addition, partially charged lead-acid batteries will suffer from sulfate damage, which greatly shortens their service life. On the other hand, lithium-ion batteries will not produce adverse reactions after they are fully charged, so golf carts can be charged for pit stops at lunch.

Energy density

The current energy density of lithium batteries is generally 200~260wh/g, and lead-acid is generally 50~70wh/G. Then the weight energy density of lithium batteries is 3~5 times that of lead-acid, which means that under the same capacity, the weight of lead-acid batteries is 3~5 times that of lithium batteries, so lithium batteries occupy an absolute advantage in the lightweight of energy storage devices.

Volume energy density

The volumetric capacity density of lithium batteries is usually about 1. 5 times that of lead-acid batteries, so under the same capacity, lithium batteries are about 30% smaller than lead-acid batteries.

Cycle Life

At present, the more popular material system is ternary lithium iron phosphate. The number of cycles of ternary power lithium batteries is usually more than 1,000 times, the number of cycles of lithium iron phosphate batteries is more than 2,000 times, and the number of cycles of lead-acid batteries is usually only about 300~350 times, so the service life of lithium batteries is about 3-6 times that of lead-acid batteries.

Price

At present, lithium batteries are more expensive than lead-acid in terms of price, which is about 2-3 times, but combined with the service life analysis, the same cost is invested, and the service cycle of lithium batteries is still longer.

Environment Pollution

Because the harm caused by lead-acid batteries in the production process or waste batteries to the environment is quite serious, from the perspective of national policies, the expansion and reinvestment of lead-acid batteries are already being restricted, or the use of lead-acid batteries is restricted in certain fields. In the future, the trend of lithium batteries replacing lead-acid batteries will become more obvious, and the progress will gradually accelerate.

How to Charge Golf Cart Battery? How to use Golf Cart Battery?

(1) The patrol car battery should be charged in time after discharge to avoid charging for more than 24 hours, otherwise the battery life will be shortened.

(2) In summer, after the vehicle is driving, the battery temperature is high, so it is not advisable to charge it immediately. Wait for the battery to cool down before charging, and do not charge it in the sun.

(3) The temperature in winter is very low, and the charge and discharge performance of the battery will be reduced when it is in a low temperature state. Charging should be carried out as close to room temperature as possible.

(4) Use the special charger equipped with the vehicle to charge the battery, otherwise it will affect the battery life and life of the battery pack.

(5) During driving, drivers should pay attention to the power indication of the instrument, and charge it in time when the power is exhausted.

(6) Vehicle storage and maintenance: If it is not used for a long time, the battery should be stored after it is fully charged, and the battery should be recharged once a month, and the full battery should be replenished once.

(7) Maintain wide-spread air circulation in the charging place.

(8) When the life of the lead-acid battery reaches the end of its life, the capacity of the battery drops sharply and cannot meet the requirements of power supply. At this time, a new battery needs to be replaced. Batteries of the same brand, the same specification, the same capacity, and the same voltage (full voltage difference <0. 1V) should be used as a group. The new battery pack should be charged evenly before use.

(9) The surface, connecting wires and bolts of the battery should be kept clean and dry for a long time. Avoid the appearance of liquid on the surface of the battery, please erase it in time if necessary.

(10) The battery connection must be maintained well. Always check the poles of the battery for oxidation and loosening of the fastening bolts to avoid heating, ignition, and burning out of the poles due to poor contact.

How to protect Golf Cart Battery? Or How to PROLONG driving mileage?

The power saving of electric golf carts can increase the driving range. The power saving of electric golf carts needs to pay attention to the following points´╝Ü

1. Avoid the rapid acceleration of the electric golf cart to start

If you start with a rapid acceleration, the current in the high-voltage circuit will be very large. Frequent rapid acceleration will affect the life of the motor controller and power battery, while shortening the driving range.

2. Avoid rapid parking of electric golf carts

Sudden braking and parking should be avoided as much as possible, because sudden braking will not only accelerate the grinding of the brake lining, but also the current feedback caused by emergency braking has an impact on the motor controller, affecting the driving range and the life of the motor controller.

3. Maintain the stable driving speed of the electric golf cart

When road and traffic conditions permit, the vehicle should maintain a stable driving speed. After the vehicle starts and accelerates to a certain speed, the accelerator pedal can be relaxed appropriately to maintain the current speed.

4. Maintain the normal tire pressure of the electric golf cart
