The liquefied gas engine belongs to the internal combustion engine, which converts the chemical energy in the fuel into the mechanical energy that drives the vehicle forward by pushing the piston in the cylinder to make a round trip movement after burning the fuel, and the battery
forklift is in the form of chemical energy into mechanical energy. The main difference between liquefied gas and battery is the difference in the ignition mode caused by the physical characteristics of the fuel, which shows their different thermal efficiency, economy and so on. A simple comparison is as follows:
Features: the battery group itself weight is large; The acceleration and starting ability of the motor is poor, and the whole vehicle is subject to the design of the battery group is not suitable for the occasion of poor road conditions.
Standard 8 hours of daily fuel: assuming the use of 80V520AH battery pack, three-phase charger input power 8.9kVA, charging time of about 10 hours, is expected to consume 100 degrees of electricity, according to the price of March 10, 2009 1.25 yuan/kilowatt calculation, need 125 yuan.
Sustainable working time: According to the amperage of the battery group, it generally takes 10 hours to charge for 8 hours of work, that is, only one shift a day can be worked.
Later procurement cost: the battery group needs to be replaced every 3 years, the cost is roughly 28,000, based on the international standard 1000 times charge and discharge calculation, the average additional cost per day: 35 yuan, in addition to the need to increase the depreciation cost of smart charger is 12 yuan per day.
The cost comparison of 250 days of work a year: 3 tons of battery
forklift, 80V520AH battery pack, charging time of about 10 hours, 250 days of work: 250 days *125 yuan/day =31250 yuan
Features: small size, light weight, good starting, cheap price, high speed when the maximum power; Low vibration and noise.
Standard 8 hours of daily fuel volume: according to the calorific value equivalent to 5.15 liters per hour, at the price of March 10, 2009 2.61 yuan/liter =4.93 yuan/kg calculation of 41 liters per day for 8 hours, about 107 yuan.
Sustainable working hours: Replace LPG cylinders for sustainable working.
Later procurement cost: the gas system is generally attached to the engine, and the user only needs to purchase a certain number of LPG vehicle cylinders according to the production situation, and the market price of each is from 150 to 200 yuan.
Comparison of the cost of 250 days of work a year: The K25 engine works 250 days on a 3-ton
forklift truck: 250 days *107 yuan/day =26750 yuan.
