The advantages of Lithium ion batteries for floor cleaning machine
As the price of lithium batteries continues to fall, lithium batteries have begun to be used in scrubbers. By comparison, lithium batteries already have great advantages. The application of lithium batteries to replace lead-acid batteries in scrubbers is becoming more and more popular. There advantages as follows: ·Cycle life more than 3000 cycles, long service life, and do not need change battery during the entire service life of ground clean machine. ·Flexible charge is available, such as charge during change water or rest. Don't worry about forgetting to charge or running out of battery. ·Maintenance free, Don't worry about charging during long time of storage. ·The price of the lithium ion battery is more competitive in the entire service life of the ground clean machine. Comparison of lead-acid and lithium batteries Item Lead acid battery Lithium ion battery（LFP） Service life 300-500 cycles, about 2 year in average 3000 cycles, same service life with machine Charge 8-10 hours needed to full charge. Usually charge for whole night after end of work. Frequent charge will shorten it`s service time. Only 1-2 hours needed to full charge. Flexible charge is available, such as charge during change water or rest. Frequent charge does not affect its service time. Working The voltage gradually decreases, the motor power gradually decreases, and the work effect will decrease in the later stage, such as the cleaning is not clean. The voltage is stable and the working effect will not decrease. Energy output efficiency About 75% About 98% Unit price Assume 1 About 2 Total price of battery in whole service life of the machine Generally change the battery 3 times, the price is 3 Solution 1. The capacity is 50% of the lead-acid battery capacity, which is equivalent to 65% of the energy output of the lead-acid battery. It can be charged at any time and without affecting actual use, the price is 1. The entire life cycle cost is 1/3 of the lead-acid battery. Solution2. The capacity is 80% of the lead-acid battery capacity, which works the same as a lead-acid battery, and the price is 1.6. The entire life cycle cost is about 50% of the lead-acid battery. Maintenance Maintenance is necessary. Charge every 1-3 months is necessary under long time of storage. Maintenance is unnecessary. Self-discharge less than 15% one year, and do not need charge during storage for one year. We designed and produced LFP batteries for floor cleaning machine, and got perfect feedback from the users. 24V 60Ah Technical parameter Model: BP2460 Electrical Specification Nominal Voltage 25.2V Nominal Capacity 60Ah Capacity @20A 3HR Energy 1536Wh Resistance ≤10mΩ Efficiency ≥98% Self Discharge ＜3% per month Cycle life ＞3000 cycles @80% DOD Charge specification Standard charge Constant current 15A.
