Is it safe if the motorhome uses lithium batteries?

Is it safe to use lithium batteries on trailers? Lithium batteries are still safer than lead-acid batteries. Have you ever seen the spontaneous combustion of lithium batteries? Have you seen the spontaneous combustion of lead-acid batteries? Even if the gas explodes, lead-acid batteries will not spontaneously ignite. Taking a step back, traditional big-brand RV manufacturers have not given up lead-acid batteries. Lead-acid batteries have a history of 150 years, and its advantage is safety and stability. Traditional RV manufacturers do not like to use lithium batteries. Because even if there is a one-millionth risk, big brands dare not take this risk, perhaps because a single incident destroyed a brand. On the contrary, some new small manufacturers, in order to meet the needs of customers, can choose batteries on lithium batteries. Lithium batteries have too many advantages over lead-acid batteries! For example, lithium batteries have higher energy density, smaller size and lighter weight. Lithium batteries have a larger capacity than batteries of the same size. High capacity density, lithium battery can choose 48V power supply system, lithium battery can choose high current discharge characteristics, can choose 48V lithium battery + 48V inverter, can supply larger capacity 220V power supply, can choose high-power electrical appliances. This is undoubtedly the biggest temptation for RV fans: large capacity and large output power! From many new energy vehicle fires and spontaneous combustion accidents, people know that lithium batteries spontaneously ignite under certain conditions. This is the biggest disadvantage of lithium batteries, especially ternary lithium batteries. The lithium iron phosphate battery is slightly more stable and is the first choice for lithium battery RVs. The disadvantage of lithium ternary or lithium iron phosphate is that once thermal escape occurs, the battery burns violently and is difficult to extinguish. Therefore, it is necessary to equip this kind of battery with a high-precision battery maintenance board. Electric vehicles are specially equipped with a battery processing system. The purpose is to prevent battery thermal runaway as much as possible, maintain the battery, and control accidents to the greatest extent. Tesla’s battery handling skills are recognized as NB, but some time ago there was a Tesla in the parking lot and it ignited spontaneously without warning! It is neither impacted by the outside nor in a charging state, which shows that no matter how good the power processing software is Neither can 100% guarantee the safety of the battery. The batteries are assembled manually by the seller, and battery maintenance boards have also been purchased. It can be sold in a stainless steel box! It is difficult to conduct a safety test! As can be seen from the above data, the lithium battery is indeed very small. It is also lighter and larger in capacity than lead-acid batteries. In theory, the danger of low-voltage lithium batteries is much lower than that of high-voltage lithium batteries in electric vehicles. Low-voltage batteries are made up of a small number of single batteries, most of which use 4 in series to achieve 12V voltage, and N batteries in parallel to expand capacity. The 12V voltage is far safer than the 500V battery pack. The stainless steel shell has better safety factor. Once the battery is found to be abnormal, throw the battery box out of the car. This battery is suitable for players and electronic enthusiasts. It is best to have a short-term maintenance talent. Monitor the size of discharge current and charging current, know what balance is, how many strings and how many in parallel, charging voltage, maintenance voltage, maintenance circuit principle, after the battery is damaged, you can find out the shortcomings of the monomer and have the talent to replace it. The advantage of lead-acid batteries is that they are cheap. Even if they die within two years, their price is only one-third of a new battery. Lithium batteries are claimed to be usable for 8 years, but the problem is that the capacity will decline. Lithium battery, our mobile phone choice, the general capacity can have a certain attenuation. After two years, the battery is not destroyed, and the standby time is greatly shortened. I want to change this time, even if the battery is not broken, or change a new mobile phone. , This is the life of lithium battery. It is not necessarily impaired, but decline in capacity is normal.
