It first cuts AC power into high frequency, then transforms and rectifies it. The intermediate link is fast, and the loss is reduced. It is not uncommon to achieve an efficiency of over 85%, and the volume is only one-third of that of a transformer of the same power. Every inch of land is valuable on a motorhome, and every kilogram must be saved. More importantly, its output voltage can be adjusted and its current can be limited; Lithium batteries are most afraid of overcharging, while lead-acid batteries are afraid of undercharging. The two types of batteries have different requirements for charging curves, and ordinary power sources cannot serve them. Switching power sources can. The car environment is bumpy, dusty, and subject to significant temperature changes. Industrial grade switch mode power supplies are also stronger than civilian plug-in power supplies. So, it&#8217;s not that the switch power supply is too advanced, it&#8217;s that the RV environment forces you to use it.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_to_Charge_RV_Batteries_With_a_Switching_Power_Supply\"><\/span><span style=\"font-family: georgia, palatino, serif;\"><strong><b>How to Charge RV Batteries With a Switching Power Supply<\/b><\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Step_1_Verify_Battery_Specifications\"><\/span><span style=\"font-family: georgia, palatino, serif;\"><strong><b>Step 1: Verify Battery Specifications<\/b><\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-family: georgia, palatino, serif;\">Before starting, make sure to understand the battery. How many volts, how many ampere hours? Lead acid, colloid, etc AGM\uff0c It&#8217;s still lithium iron phosphate, which determines all the parameters later on. There is a label on the battery casing, but there is no instruction manual written on the label. The 12V system and 24V system cannot be mixed, and the full voltage point is also different. Lead acid is about 14.4 volts, lithium iron phosphate is about 14.2 volts, and the float charging voltage needs to be even lower. Capacity determines the charging current, and it is more reliable to choose one tenth to one-fifth of the capacity based on experience; A 100 ampere hour battery with a current of ten to twenty amperes is sufficient. Don&#8217;t turn on the current all at once, as the battery heats up and its lifespan drops quickly.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Step_2_Select_a_Power_Supply_with_Current_Limiting\"><\/span><span style=\"font-family: georgia, palatino, serif;\"><strong><b>Step 2: Select a Power Supply with Current Limiting<\/b><\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-family: georgia, palatino, serif;\">Choose a power supply with an output voltage range that can cover the fully charged voltage of the battery and leave enough current margin. The restriction of flow cannot be omitted. If a power supply without current limiting function is connected, the current will rush out instantly, which can cause tripping or blackening of the wiring terminals. The best option is to have a constant current and constant voltage curve. First, charge the battery with a constant current, and once the voltage reaches the set value, it will automatically switch to a constant voltage. Then, slowly reduce the current to match the curve provided by the battery manufacturer. On the input side, it also depends on whether it is connected to the mains or the vehicle generator, and if the voltage level is selected incorrectly.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Step_3_Configure_Precise_Output_Voltage\"><\/span><span style=\"font-family: georgia, palatino, serif;\"><strong><b>Step 3: Configure Precise Output Voltage<\/b><\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-family: georgia, palatino, serif;\">Get the power supply, don&#8217;t connect the battery yet. Turn down the voltage knob in the unloaded state, use a multimeter to measure the output terminal, and turn the voltage to the full charge value given by the battery manufacturer. A difference of 0.1 volts will result in a different battery state after long-term use; Lithium batteries are particularly sensitive, with high bulges and insufficient charging. Temperature compensation also needs to be considered. When the battery is cold, the charging voltage should be raised, and when it is hot, it should be lowered. Some power supplies come with temperature probes that can be connected. Adjust the voltage, then tighten the current limit to the current calculated in the previous step, and test with a light load to see if the meter needle is stable.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Step_4_Connect_the_Battery_Safely\"><\/span><span style=\"font-family: georgia, palatino, serif;\"><strong><b>Step 4: Connect the Battery Safely<\/b><\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-family: georgia, palatino, serif;\">The wiring sequence is particular. Connect the positive pole first, then the negative pole, and finally power on; When disassembling, reverse the process by first disconnecting the power supply and then removing the negative pole. The wire should be thick enough, the wire diameter should be calculated according to the current, and the voltage drop should be controlled within 0.5 volts. Secure the terminal firmly and do not let the bare copper wire sway back and forth. The fuse cannot be missing. Connect it on the positive wire, closer to the battery, and it will disconnect instantly in case of a short circuit. The car is shaking, the connector is loose and heating up, and I have heard of the incident of a fire in the middle of the night. Don&#8217;t close the circuit after connecting, check the positive and negative poles again.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Step_5_Monitor_Charging_Performance\"><\/span><span style=\"font-family: georgia, palatino, serif;\"><strong><b>Step 5: Monitor Charging Performance<\/b><\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-family: georgia, palatino, serif;\">On the power line, keep an eye on the first half hour. Is the ammeter crawling near the current limit, is the voltage steadily increasing, and the battery feels warm to the touch, rather than hot to the touch. When the voltage reaches the set value, the current should slowly decrease; If the current does not decrease continuously, it indicates that there is a problem with the battery or the power supply is not entering a constant voltage. Install a coulomb meter or Bluetooth module, and you can check the voltage and current on your phone, which is more convenient than squatting by the car and staring at the meter. Record data once a week, including how many volts it has been charged to, how many hours it has been used, and how high the battery temperature is. Save it up for a month, and you can tell at a glance whether the battery is healthy or not.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_to_Choose_the_Best_Switching_Power_Supply_for_RV_Battery_Charging\"><\/span><span style=\"font-family: georgia, palatino, serif;\"><strong><b>How to Choose the Best Switching Power Supply for RV Battery Charging<\/b><\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-family: georgia, palatino, serif;\">There are many switch mode power supplies on the market, don&#8217;t just focus on power. Let&#8217;s first look at efficiency. A higher efficiency can save a considerable amount of electricity in the long run; Looking at the ripple again, a large ripple is not friendly to lithium batteries, and the car TV screen will also be interfered with. Wide voltage input, isolation type structure, it is best not to save on isolation in the vehicle environment, so that the battery will not be dragged down together in case of failure. The working temperature range should cover the driving season, from minus 20 degrees Celsius to over 70 degrees Celsius, and the specifications should be written in the specification book. Fan noise, volume, installation method, these things that deal with you every day, the parameter table is not conspicuous, it is all a matter of use. If possible, ask the manufacturer for samples for testing, don&#8217;t just look at the e-commerce page.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Why_WEHO_is_the_Right_Solution\"><\/span><span style=\"font-family: georgia, palatino, serif;\"><strong><b>Why WEHO is the Right Solution<\/b><\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-family: georgia, palatino, serif;\"><a title=\"C1000 \u0936\u0941\u0926\u094d\u0927 \u0938\u093e\u0907\u0928 \u0935\u0947\u0935 \u092f\u0942\u092a\u0940\u090f\u0938 \u0938\u094d\u0935\u093f\u091a\u093f\u0902\u0917 \u092c\u093f\u091c\u0932\u0940 \u0915\u0940 \u0906\u092a\u0942\u0930\u094d\u0924\u093f\" href=\"https:\/\/www.wehopower.com\/hi\/product\/c1000-pure-sine-wave-ups-switching-power-supply\/\" target=\"_blank\" rel=\"noopener\"><span style=\"color: #0000ff;\"><strong><b>\u0935\u0947\u0939\u094b<\/b><\/strong><\/span><\/a>\u00a0has been producing industrial power supplies for some years, with product line widths ranging from tens of watts to over kilowatts.

After the voltage reaches the set value, the power supply automatically limits the current, and the current decreases as it charges. Finally, it floats on the float voltage and does not continue to rise. The model with temperature compensation moves the voltage point when the ambient temperature changes, so it is not necessary to charge the battery in summer.<\/span><\/p>\n<p><span style=\"font-family: georgia, palatino, serif;\">Q3:What power supply size is required for RV battery charging applications?<\/span><\/p>\n<p><span style=\"font-family: georgia, palatino, serif;\">Look at the battery capacity, and also at how quickly you want to fully charge it. A 12 volt battery with 100 ampere hours requires around 120 watts at 0.1C and 240 watts at 0.2C. To run fast, increase the current and power accordingly; Choosing too much power is wasteful, choosing too little is slow to charge, just reverse according to daily electricity habits.<\/span><\/p>\n<p><span style=\"font-family: georgia, palatino, serif;\">Q4:Are industrial switching power supplies suitable for RV systems?<\/span><\/p>\n<p><span style=\"font-family: georgia, palatino, serif;\">Can be used, but choose. Industrial models are usually fixedly installed and do not rely on portability. The fan noise may be too loud, and the protection level of the casing should be sufficient. The interface form should match the distribution panel on the car. Just take it and install it, occasionally encountering problems such as incorrect size and noisy noise; Choosing a customized car version will save a lot of trouble.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span><span style=\"font-family: georgia, palatino, serif;\"><strong><b>\u0928\u093f\u0937\u094d\u0915\u0930\u094d\u0937<\/b><\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-family: georgia, palatino, serif;\">Switching the power supply to charge the<span style=\"color: #0000ff;\"> <a style=\"color: #0000ff;\" title=\"C1000 \u0936\u0941\u0926\u094d\u0927 \u0938\u093e\u0907\u0928 \u0935\u0947\u0935 \u092f\u0942\u092a\u0940\u090f\u0938 \u0938\u094d\u0935\u093f\u091a\u093f\u0902\u0917 \u092c\u093f\u091c\u0932\u0940 \u0915\u0940 \u0906\u092a\u0942\u0930\u094d\u0924\u093f\" href=\"https:\/\/www.wehopower.com\/hi\/product\/c1000-pure-sine-wave-ups-switching-power-supply\/\" target=\"_blank\" rel=\"noopener\"><strong><b>RV battery<\/b><\/strong>\u00a0<\/a><\/span>is not just about plugging it in. Confirm the battery specifications, select the correct model with current limiting, adjust the voltage under no-load, connect the wires in sequence, and then focus on the data from the first half hour. By taking these steps, the battery can be used for several more years. Don&#8217;t compromise on parameters, don&#8217;t save on margin, and don&#8217;t save on fuses. I really don&#8217;t want to tinker with it myself. Finding a manufacturer that can customize the curve according to your battery is more reliable than asking for advice on forums for a long time.

Many people have encountered this before. The mains power cannot be connected, and the generator is noisy. How to replenish the electricity? You need to think carefully before going out. Switching power supplies have been increasingly installed in cars in recent years, with small size, low heat generation, and higher efficiency than old-fashioned transformers. They can be used with lead-acid and lithium batteries. But every step of wiring, voltage regulation, and current limiting must not be taken lightly; If connected incorrectly once, the battery may become useless. Below, we will explain the entire process step by step, from confirming specifications to daily monitoring.<\/p>","protected":false},"author":4,"featured_media":18732,"parent":0,"menu_order":76,"comment_status":"closed","ping_status":"closed","template":"","format":"standard","meta":{"_acf_changed":false,"_joinchat":[],"footnotes":""},"news_category":[149,148],"class_list":["post-18368","news","type-news","status-publish","format-standard","has-post-thumbnail","hentry","news_category-blog","news_category-industry-news","entry"],"acf":[],"post_mailing_queue_ids":[],"_links":{"self":[{"href":"https:\/\/www.wehopower.com\/hi\/wp-json\/wp\/v2\/news\/18368","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.wehopower.com\/hi\/wp-json\/wp\/v2\/news"}],"about":[{"href":"https:\/\/www.wehopower.com\/hi\/wp-json\/wp\/v2\/types\/news"}],"author":[{"embeddable":true,"href":"https:\/\/www.wehopower.com\/hi\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/www.wehopower.com\/hi\/wp-json\/wp\/v2\/comments?post=18368"}],"version-history":[{"count":4,"href":"https:\/\/www.wehopower.com\/hi\/wp-json\/wp\/v2\/news\/18368\/revisions"}],"predecessor-version":[{"id":18733,"href":"https:\/\/www.wehopower.com\/hi\/wp-json\/wp\/v2\/news\/18368\/revisions\/18733"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.wehopower.com\/hi\/wp-json\/wp\/v2\/media\/18732"}],"wp:attachment":[{"href":"https:\/\/www.wehopower.com\/hi\/wp-json\/wp\/v2\/media?parent=18368"}],"wp:term":[{"taxonomy":"news_category","embeddable":true,"href":"https:\/\/www.wehopower.com\/hi\/wp-json\/wp\/v2\/news_category?post=18368"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
