First, long service life, environmental protection and safety Lithium iron phosphate (LiFePo4) battery cycle times: 3000>2000 (ternary lithium) >450 (lead-acid battery) For example: driving a golf cart every day to charge and discharge once, the service life of lead-acid batteries is about 1~2 years, ternary lithium is about 3~5 years, and lithium iron phosphate is more than 5~8 years. The lead in the lead-acid battery is a heavy metal, which is easy to cause pollution and environmental protection, and is large in size and weight under the same parameters. Ternary lithium batteries are flammable and explosive, and their safety is poor. The driving mileage under the same parameters is 20% more than that of lead-acid. Lithium iron phosphate batteries are used a lot in E-Z-GO, CLUB CAR, and Yamaha brand cars, and the three major brands have a utilization rate of more than 85% in golf courses in the United States. At present, 48V100AH, 48V125AH, 48V150AH lithium iron phosphate batteries are used to replace the previous lead-acid batteries. There are also a large number of new cars that use lithium iron phosphate batteries as environmentally friendly new energy.
Specification of Battery
1. Battery cell + BMS (battery protection board) + shell (outer packaging) + printing 2. The battery cell A+ (CATL) is used more than 4000 times of deep discharge, and the price is about 1350 yuan per kWh. The use of battery cells (EVI, Guoxuan, BYD, etc.) cycle more than 3000 times deep discharge, the price of 1250 yuan per kWh. The core BMS of technology can not only protect the battery, but also intelligently manage and maintain each battery cell, prevent overcharge and overdischarge of the battery, extend the service life, and monitor the status of the battery. The BMS battery management system is connected to the server side via a wireless communication module (Bluetooth). Our company has 8 years of golf cart battery manufacturing experience, stable and reliable technology, long warranty time. (Battery cells are guaranteed for 3 years, accessories are guaranteed for 1 year.) Counting from the date of shipment)
confirm how much power (KW) the motor is, how much voltage (V), and the motor voltage is consistent with the battery voltage
Customer's previously used battery parameters
Confirm the customer's previously used battery capacity (AH) for selection
Installation location of golf cart battery
Know the installation location and size of the customer's battery, and whether our battery needs to be adjusted
Ask customers if they need to bring a charger
Each battery must have its own charger and cannot be shared (chargers sold separately)
Customer charging time for golf cart
How long do you plan to charge it? Normal 4~5 hours full charge, 0.2C rate, can speed up 0.5C

the parameters that need make confirm
1. The brand and model of the golf cart (this optional question, appear professional) 2. The voltage and power of the motor (voltage is to determine the voltage of the battery, and the power can determine the use of the maximum current) 3. The location size of the battery needs specific size (the basis for structural engineers to design the size of the battery) 4. Whether to connect the communication (if the customer needs, need to provide the communication protocol, our engineers cooperate with the program, if not needed, we can bring our own SOC instrument on the battery) 5. Whether a Bluetooth link is required. (It is convenient to observe the battery parameters on the mobile phone, and the cost increases by about 300 yuan) 6. Is it necessary to equip a charger (what kind of plug is the charger?) The length of this warranty is best distinguished from the battery) 7. How far does this golf cart battery have to run? (48V100AH about 60-80km .48V120AH about 70-100km 48V150AH about 90-130km)
Installation: The size of the customer's battery compartment is larger than the size of the battery can be installed (the battery compartment refers to the location where the battery is installed, and in the case of general lead-acid replacement, our battery is about one-third smaller than the lead-acid battery). Figure 1 There will be a 4*10mm screw hole on our battery box, which can be fixed by locking screws or fixed in other ways (without loosening and not harming the battery). Domestic common red for positive interface, black for negative interface. The upper right is the battery switch button, and the upper left is the communication interface. The general communication interface is connected to the instrument and then the data cable is connected to the keyhole switch of the golf cart, which is set to linkage (when the battery switch is started), and the customer can use the golf cart normally as soon as he starts.
Warranty: The battery itself does not have many wearing parts. If there is damage such as buttons, our factory will give priority to online guidance for maintenance. The battery cell is not easy to be damaged (Ningde, Yiwei, Guoxuan and other standard products), if the quality of the product itself is a problem, our factory will replace it.
Battery life: Now most of the foreign golf cart battery voltage is 48V, and there is a small amount of 36V battery. Most of the voltage of sightseeing cars exported from China to foreign countries is 72V. Our company counts the approximate cruising range, such as: (48V100AH about 60-80 km .48V120AH about 70-100 km 48V150AH about 90-130 km) The endurance is determined according to the load, driving conditions, driving habits, wind speed, slope, temperature and other factors of the car. Whether the customer drives to buy vegetables or play golf, try to complete the task and charge, so you need to design the margin for the customer. For example, play a golf (18 holes) round trip about 20 kilometers (the length of golf courses in each country is different), the number of uses is one in the morning and one in the afternoon, and the customer intends to charge once a day (because the charging time is 2~5 hours), then it is necessary to design a minimum of not less than 50 kilometers. The battery can not be fully discharged, and if you need to keep a little margin, it is designed for about 55 kilometers. If you can run a little more distance, there will be no range anxiety.
intelligent controlBuilt-in intelligent battery management system, and can communicate with any controller system via Bluetooth, CANbus, RS485, RS232 to monitor the working status of the lithium battery in real time. high discharge capacityLithium batteries can withstand 80% DOD and maintain good battery life (more than 2500 times). This means more time for your ships to perform tasks and less time "wasting" recharging.fast chargingIn the same volume, lithium batteries have more energy available. In other words, the same power and lighter weight, or the same weight and more power, the energy density of lithium batteries is 3 times that of lead batteries. long lifeLithium batteries have longer charge and discharge cycles, so they have a longer lifespan. Under the same DOD conditions, the cycle life of lithium batteries is about 3 times that of lead-acid batteries. more efficientThe efficiency of lithium batteries is close to 95%, while the efficiency of lead-acid batteries such as AGM or gel is only 80-85%. Conversely, lead batteries lose 15-20% anytime their age increases, which means you need more time to top up an AGM or GEL battery.cut costsThere is no need for engine maintenance, fuel costs, fuel storage costs, and workshop supply costs, greatly reducing training costs.Increased safety: zero fuel emissions, no need to store flammable fuels on site, low dBa sound level.Improve working time: meet the needs of the whole work without refueling or changing the fuel tank
