Pacific Automotive Network uses ternary lithium batteries for motorhomes. If you are often parked without mains power, it is recommended to install 600-1000AH, which can basically guarantee 6-9 kWh of electricity every day. Coupled with rooftop solar, it is recommended to have 400-600W (provided that the roof area is sufficient), which can convert about 1 kilowatt hour of electricity and recharge the auxiliary battery for a long time. period.
Electricity is one of the sources of water and electricity necessary for the lifespan of motorhomes. Although motorhomes have batteries with some reserve capacity when they leave the factory, they usually come standard with 1-2 batteries to store electricity. , generally 100Ah-200Ah, which can basically meet the needs of simple electrical appliances such as lighting and rice cookers in thes motorhomes. It can only be said that it is barely enough. If you want to use it a little more "intentionally", many people usually "grow" the battery after purchasing a new car.
At present, batteries used in motorhomes are generally equipped with lead-acid batteries or gel batteries when they leave the factory, but their defects are also obvious, that is. is why many people choose to use lithium iron batteries when modifying. circuits However, the safety of lithium iron batteries needs improvement, and other defects are also a major shortcoming that limits their large-scale application.
As a traditional energy storage device, lead-acid batteries are currently more common, especially RV manufacturers are more willing to use them. Its advantages and disadvantages are equalement obvious: Lead-acid batteries are favored by RV manufacturers for their high safety, low price and stable performance. They have become the preferred product of major RV companies and are currently the most commonly used batteries in RVs. .
Disadvantages The biggest drawback of lead-acid batteries is their heavy weight. Take the example of a 100 Ah lead-acid battery. Its single weight is about 30 kg, and that of 200 Ah is about 60 kg. It is relatively bulky and large.
Lithium batteries With the development of new energy, great progress has been made in the research, development and use of lithium batteries, and many motorhome modifications have begun to use lithium batteries. Currently, the most common lithium batteries on the market include lithium batteriesIron phosphate and lithium iron phosphate batteries are mainly used in motorhomes because they are safer and more stable.
Advantages Compared with lead-acid batteries, lithium iron batteries have obvious advantages in charging and discharging efficiency, energy storage, volume and weight. The volume of a lithium-iron battery with the same specifications is basically only half that of a lead-acid battery, and its volume is only about one-third. Lithium-ion batteries have higher charging and discharging efficiency and longer life.
Disadvantages The disadvantages of lithium batteries mainly lie in two safety aspects: on the one hand, the price of lithium batteries is almost twice or more than that of lead-acid batteries, and the cost of usage is higher, however, the quality of lithium batteries is not very stable andsecurity needs to be improved.
However, as the advantages of lithium batteries are more obvious, more and more people choose to install lithium batteries to store electric energy. However, lithium iron phosphate batteries are generally preferred due to their greater stability. Many new energy vehicles that ignited spontaneously before were all ternary lithium batteries.
