Take the example of a 12v800ah lithium battery, which represents approximately 10 kilowatt hours of electricity. Lithium batteries are batteries that use non-aqueous electrolytes. they have no memory effect and can be charged instantly. Ready to use and does not require long-term charging or activation. Lithium batteries are available in different categories and can be selected based on usage requirements.
Notes on the use of electrical appliances:
1. Electric vehicles and other equipment cannot be charged. It may be necessary to use a special AC adapter for charging.
2. Rechargeable batteries for household appliances cannot be used and must be handed over to specialist recycling agencies.
Main advantages:
The 26650-3AH lithium iron phosphate battery has been overchargedchanged to 3C10V and the battery exploded. The test was repeated with similar results. When a lithium battery is charged and discharged with high current, the temperature inside the battery continues to rise and the gas generated during the activation process expands.
As the internal pressure of the battery increases and the pressure reaches a certain level, if the outer shell is damaged, it will burst, causing leakage, fire or even explosion. Therefore, everyone should pay attention to safety when using it.
What is the appropriate size of the camper battery?
If the voltage of a 600 Ah lithium battery is 3.7 V, 600 × 3.7 = 2220 Wh, 2220÷1000=2.22, the voltage is 3.7 V and can store 2.22 kilowatt hours of electricity.
Battery refers to a cup, tank or other container or part of a composite container thatcontains an electrolyte solution and metal electrodes to generate electric current. This is a device that can convert chemical energy into chemical energy. electric energy. It has positive and negative poles. With the advancement of technology, batteries generally refer to small devices capable of producing electricity. Like solar cells. Battery performance parameters mainly include electromotive force, capacity, specific energy and resistance.
Using the battery as a power source can achieve stable voltage, stable current, stable power supply for a long time and little influence from the outside world. In addition, the battery structure is simple, easy to carry. and charging and discharging operations are simple and easy. It is not affected by external climate and temperature, has stable performance andreliable and plays a big role in all aspects of modern social life.
In a chemical battery, the direct conversion of chemical energy into electrical energy is the result of spontaneous chemical reactions such as oxidation and reduction inside the battery. This reaction takes place on two electrodes. The negative active material consists of negative potential and stable reducing agents in the electrolyte, such as zinc, cadmium, lead and other active metals and hydrogen or hydrocarbons. The positive active material consists of positive potential and stable oxidants in the electrolyte, such as manganese dioxide, lead dioxide, nickel oxide and other metal oxides, oxygen or air , oxygen-containing acids and their salts, etc.
Electrolytes are materials with good ionic conductivity, such as aqueous solutions of acids, alkalis and salts, solutionsnon-aqueous organic or inorganic products, molten salts or solid electrolytes. When the external circuit is disconnected, although there is a potential difference (open circuit voltage) between the two poles, there is no current and the chemical energy stored in the battery is not transferred. Replaced by electrical energy. When the external circuit is closed, current flows in the external circuit due to the potential difference between the two electrodes.
RV batteries on the market are generally 200 Ah, 12 V standards, using lithium batteries, and the most extreme can even reach 800 Ah. Compared with traditional batteries, lithium batteries have higher charging efficiency and can be fully charged within a few hours; they have high energy storage and can be used for several months on a single charge, they are small in size andt lightweight, making them easy to use. easy to carry and replace.
Looking back at the demand, the general cooling power consumption of air conditioners is about 800W, the heating power consumption is about 2500W, the power consumption of refrigerators is about 800W, about 50 W, the power consumption of televisions is about 200 W., water heaters are about 1000 W, and induction cookers are about 800 W. As for lighting and electronic equipment, power consumption is relatively low. Of course, there are relatively few extreme situations in which these devices are used at the same time. Take as an example the use of air conditioners for refrigeration in summer.
If there is no external AC power or there is no generator, you can only rely on battery storage to provide energy. DuringIn hot summers, air conditioning is naturally necessary for sleeping. If it is turned on for 8 hours per night and calculated based on a cooling power of 800 W, the power consumption per night is 6400 W, or 6.4 kWh.
Common RV batteries on the market now include 240 Ah, 400 Ah and even 800 Ah in extreme cases. As for lead acid batteries or lithium batteries, that's a matter of opinion, so I won't go into detail here. However, since the battery cannot discharge electricity, the lead-acid battery is generally 60% of the rated capacity, the lithium battery is generally 80%, and the RV battery is generally 12V. Calculated on the base with a capacity of 800 Ah, lead. -the acid battery has a storage capacity of 800*12*0.6=5760, or 5.67 kilowatt hours of electricity; the storage capacity of lithium battery is 800*12*0.8=7680,or 7.68 kilowatt hours of electricity.
The above calculation shows that just using the air conditioner, even if the car battery uses a large capacity of 800 Ah, it can be used for 8 hours . one night, and it still does. Other electrical equipment cannot be taken into consideration. As for factors affecting usage such as environment and temperature, they will not be considered here for the time being. As for battery mitigation under long-term saturated use, the cost increase caused by the early battery replacement cycle is an extra-budgetary expense.
