Car engine oil can be used for gasoline generator oil.
1. Let the generator run until the body warms up, then drain the used oil.
2. After draining the used oil, plug the oil drain hole and add gasoline into the body to clean the remaining used oil inside the body.
3. If possible, you can place the generator on the vibrating pump and vibrate it for a while to clean it completely. If there are no conditions, you can let the gasoline soak in the fuselage for a while.
4. Release the gasoline at the end until the gasoline is drained. Add new engine oil up to the mark on the oil dipstick.
Generator maintenance methods:
After the operation of the new generator or sealed generator (the first 50 hours), the following maintenance work is carried outwho:
< p>1 . Clean or replace the air filter.2. Replace the engine lubricating oil.
3. Replace or clean the filter element of the lubricating oil filter.
4. Tighten all bolts and nuts.
New generators should try to avoid sudden load increases or high speed operation, and use the manufacturer's recommended lubricating oil whenever possible. Do not mix lubricating oils from different brands. Lubricating oils contain various additives. . Mixing lubricating oil will reduce lubrication performance and cause abnormal wear of moving parts.
Hello, the range extender should be more efficient
The voltage generated by the generator is 220v If you are charging a vehicle electric, you need to use an electric vehicle charger. Electric vehicle charger steps down from 220V to uvoltage suitable for charging the battery. For example, if the electric vehicle battery is 48 V, the output voltage of the charger should be 54-56 V. There is an efficiency problem between reducing the voltage from 220 volts to 54-56 volts. Generally, the efficiency of a switching power supply charger is around 80%, which means that the final utilization rate of a 3000 watt generator is around 2400 watts (the theoretical value calculated is actually less than this), of which 600 watts of power are lost during the conversion process! And because the output current of a home electric vehicle charger is relatively low, it takes more than four hours or even longer for a full charge. That is, the energy supplied by the motor during charging is still wasted (the electricity generated by the generator is stored there and the charger cannot use as much. This is equivalent to the generatorator is a one-inch water pipe that is constantly dripping. of water, and the charger is equivalent to A quarter point faucet is installed on the one inch water pipe of the generator When fully opened, it can only use a quarter of the water) < /p>
But the range extender is different and charges the same (48V battery), the range extender only needs to output 54 to 56 voltage. It automatically adjusts the speed according to the voltage of the battery (so it is more efficient) and the charging current is also higher than that of a home charger. Charging is also faster. However, it is not recommended to use the range extender in place of a home charger for a long period of time. Because the charging current is higher than that used at home. This will damage the battery for a long time. (Different types of range extenders have different functionstes) For example, a 3,000 watt range extender has In terms of wattage, 3,000 divided by 54 volts is about 55 amps. Therefore, you should pay attention to this issue when choosing to use a repeater. However, with a rated power of 3000 watts, it is impossible to produce 3000 watts continuously under full load, and the safe power for a long time is only about 1500-2000 watts. But the current reached about 20 amps! Compared to batteries with a capacity of more than 150 amps, this is possible and will not be overcharged. The battery capacity of small electric vehicles is basically 20 to 40 amps. Then the safe charging current of this battery is around 2-4 amps, and charging with a total current of 20 amps will definitely shorten the lifespan.
When using the range extender to stop and charge, you should pay attentionion to the charging current and avoid overcharging.
Which is better, the gasoline range extender for electric vehicles or the 220v gasoline generator with rechargeable bottle?
No matter how you calculate it, the extended runtime gasoline generator is better, because the output voltage of a 220V gasoline generator is 220 V, while the output voltage of electric vehicles is not lower than This voltage is higher than this voltage. Electric motorcycles will be lower than this, typically 48V-96V, while electric cars are much higher than 220V, and they all use DC. Electricity generated by gasoline generators must use switching power. Foods or liters. The voltage conversion circuit is then rectified to the applicable voltage before charging, and the loss in this process is relatively large. LThe conversion efficiency of commercially available switching power supplies is generally 80% to 90%, and there are also more. these, like more than 99%, but these The price is extremely high, and electric vehicles will not use such expensive power supplies!
Therefore, this loss of 10 to 20% is very considerable. Additionally, due to the relationship between the windings and the fuel tank, the volume and weight of the 220 V gasoline. The generator is significantly larger than the extended range motor. This extra weight also uses energy! So if you choose, there is nothing to say!
The extended range type seems relatively simple and straightforward
The 220V type has various accessories such as output management
If you choose dual-use, if the extended range is used occasionally and is generally used most of the times in a 220 V environment, choose the 220 V type! If it is used with extended range, then the extended range model has no choice, otherwise it will be difficult for itself!
The range extender only needs to output a voltage of 54 to 56. It automatically adjusts the speed according to the battery voltage (so it is more efficient) and the charging current is also higher than that of a home charger. Charging is also faster. However, it is not recommended to use the range extender in place of a home charger for a long period of time. Because the charging current is higher than that used at home. The voltage output by the battery generator for a long time is 220V. If you charge an electric car, you must use an electric car charger. The electric car charger reduces the 220V to a suitable voltage to charge the batlaugh. the electric car battery is 48V, then the charger output. The voltage should be 54-56 V. There is an efficiency issue between reducing the voltage from 220 volts to 54-56 volts. Generally, the efficiency of switching power supply charger is about 80%. Exactly, it means that the final utilization rate of the 3000 watt generator is about 2400 watts (the theoretically calculated value is in reality lower than that), of which 600 watts of power are lost during the conversion process! And because the output current of a home electric vehicle charger is relatively low, it takes more than four hours or even longer for a full charge. That is, the energy supplied by the motor during charging is still wasted (the electricity generated by the generator is stored there and the charger cannot use as much. This is equivalent to the generator being a leaking one inch water pipeconstantly fighting. water, and the charger is equivalent to A four-point faucet is installed on the one-inch water pipe of the generator. It can only use a quarter of the water when fully opened)
Gentlemen who use electric vehicle range extenders a lot There are misunderstandings in use. In other words: only start the range extender when the electric vehicle battery is almost exhausted. This is highly undesirable. If the range extender is turned on at this time, it will charge the battery on the one hand and run the engine on the other. This will cause the range extender to be overloaded and easily damaged. . I recommend charging the electric vehicle with mains electricity before departure (mains electricity is cheaper) and then starting the range extender. If the journey is not far, it is not recommended to usea range extender (it is not recommended to increase the cost by 20%). more than four times).
To put it simply, the voltage symmetrical range extender is a straight path, and the 220 volt generator comes back in a big circle, so it's always about 'a range extender. GOOD.
One kilowatt motor with one kilowatt generator, 80 to 85 percent conversion efficiency. A charger with a good conversion rate, which can reach 85%, consumes between 15% and 200-30% more during the journey. Because some mediocre charging equipment can't even reach 70%, let's go straight.
Range extenders are an illusion.
It seems like it might extend the reach, but in reality it doesn't do any good.
Cars generally require 30 to 50 kW of power to maintain normal driving.
Find an electric group30 kW gasoline trogen, which is a gasoline car with an additional generator.
The 3 kW gasoline generator can be used for automobile lighting,,,,
It n It's not flexible enough to charge the power bank.
Hello, the efficiency of the electric range extender is higher. The 220 volt generator is very inefficient when recharged from the battery via a charger. In fact, so is the effectiveness of the electric range extender. very weak. It is best used in an emergency. Yes, no motorcycle is more efficient when driving directly with wheels, because it converts mechanical energy into electrical energy, the battery discharges and the mechanical energy is transferred to the motor. In this way, a lot of losses are lost, so there are a lot of electric vehicles now, and some places do not check electric vehicless. The fatal weakness of electric vehicles is their short range, so now people are forced to install boosters in the city!
The use cost of the range extender fuel generator is high, and the electricity output is converted into electric energy.The utilization rate is low. In comparison, of course, installing photovoltaic panels on the roof for basking in the sun to supplement electric power and increase the mileage of electric vehicles is more efficient and has a low running cost.
(1) Now the voltage of electric vehicles is DC: 48 V, 60 V, 72 V.
(2) Gasoline generators Ordinary ones generate 220 V AC, which must pass through a charger (rectifier transformer) to charge the electric vehicle battery. Constant voltage and low current charging.
(3) The gasoline range extender for electric vehiclesiques is a direct current gasoline generator. It directly produces DC power corresponding to electric vehicles.
The propulsion circuit allows the electric vehicle to move; at the same time, there is also a charging circuit (protection and regulation function) which can charge the electric vehicle battery; .
(4) As long as the electric vehicle, generator, charger and range extender are of good quality. Their application effects are all ok.
Of course, this saves money more directly. The electricity generated by the engine range extender is used directly. The electricity produced is charged with a charger, and there are problems such as loss and conversion rate.
