At present, domestic RVs are only equipped with lead-acid batteries of about 200AH when they leave the factory. When the RV is traveling outside, the provision of water and electricity is very important. Just like at home, the electricity must not be stopped for a moment, otherwise, it will seriously affect the mood of traveling. The power of a lead-acid battery is about half of the marked amount in actual use. The power of a 12v200AH lead-acid battery is about 1200 watt-hours, which is 1.2 degrees. Lithium iron phosphate battery, nominal 12v400AH, theoretical power can reach 4.8 kWh, 1000AH power can reach 12 kWh, 4.8 or 12 kWh is all the power that can be used, unlike lead power, which can only use half. When the RV is parked, the TV, refrigerator, lighting, mobile phone, tablet computer, and rice cooker all need electricity. 1 kWh is seriously insufficient. Therefore, it is the general trend to equip large-capacity lithium batteries.
Many car users have installed large-capacity lithium batteries for RVs. When using electricity in an RV, the first thing to consider is the safety of electricity. There are several aspects of safety: one is the safety of the battery when the RV is driving, and the battery can withstand the bumps on the road. This is one aspect, and the other is the safety of electricity consumption when the RV is parked. Including high current discharge, the battery's high-temperature tolerance in summer, and the battery's low-temperature tolerance in winter. In addition, one of the most important aspects of the use of lithium batteries is to have an advanced power management system. Unlike our daily use of dry batteries or lead-acid batteries, this type of battery does not require power management, and the characteristics of lithium batteries determine During the use of lithium batteries, a reliable and advanced power management system must be provided to ensure the safety and stability of the lithium batteries. The mobile phones we use every day use a ternary lithium battery, which also has a power management system, and the lithium iron phosphate battery is no exception. If the lithium battery is not equipped with an advanced and reliable power management system, and the lithium battery is directly charged and discharged, it will cause disadvantages such as overcharge, over-discharge, and overcurrent. The direct result is that the lithium battery is quickly scrapped. In addition to preventing the occurrence of the above-mentioned undesirable conditions, the advanced power management system also has functions such as short-circuit protection and over-temperature protection.
At present, in terms of cost performance, lithium iron phosphate batteries are more suitable for deployment in motorhomes. First, it has higher safety and is safer than ternary lithium batteries. Lithium iron phosphate batteries will not burn or explode during a collision. , This ensures the safety of the battery of the RV in the process. The second is that the lithium iron phosphate battery has a higher power density. The same power is more than half lighter than a lead-acid battery, and it can be discharged at a large current. A single set of batteries can drive 2000 watts of electrical equipment, and the battery itself does not generate heat or produce There is very little heat. Now the so-called graphene battery is not cost-effective. For most RV enthusiasts, it is an ideal choice to install a suitable lithium iron phosphate battery on the RV.
For many RV players, there are many lithium battery manufacturers on the market, and the prices are different. They are worried about the quality of the battery, how long it can be used, whether it is safe, and the service life. It is understandable that although lithium iron phosphate batteries have many advantages, they are relatively similar. Compared with lead electricity, the price is more expensive. There are sellers in the market who use second-hand lithium batteries, that is, disassembled batteries to assemble. The price is definitely cheap, but the battery capacity and service life cannot be guaranteed. Second, batteries of the same capacity are used. Second-hand batteries are relatively heavy, and second-hand batteries are basically in use. The battery is in use without a protection board, and the service life is severely low again, which is incomparable with a brand new battery. Regarding the life of the lithium battery, what does it mean that the new lithium iron phosphate battery has more than 2000 cycles? That is to say, the battery is fully charged to the battery is fully discharged, it is counted once, as long as the battery is charged, it is not a complete cycle. After the lithium battery is equipped with a protection board (that is, the power management system), it is basically impossible for the battery to be completely discharged. The battery voltage is about 10v, the circuit board will disconnect the battery and no longer supply power, but the battery There is still voltage. After the protection board is added, the battery can theoretically be used for a long time without worrying about the service life. Generally, it is no problem to use 8 to 10 years, but the power will be slightly reduced as the life is extended.
