How to quickly select
marine lithium batteries.
Electric boats are an inevitable product of the intelligent and green development of ships. On the one hand, they are pollution-free and have positive significance in protecting water resources and air. On the other hand, they are clean for users in terms of storage, transportation, and use, with no unpleasant gasoline smell, oil pollution, or waste gas; The second is safety. Gasoline, liquefied gas, and diesel are all flammable and explosive, and there are risks during operation. Electric outboard engines do not need to worry about such risks at all; Thirdly, the propulsion efficiency is high, and the output characteristics of low speed and high magnification are very suitable for ship propulsion; Fourthly, the usage cost is low, and the cost of daily charging is much lower than the cost of purchasing fuel. Due to its simple structure, fewer rotating parts, and reliable operation, the maintenance cost is extremely low; The fifth is that storage, transportation, and use are all very convenient, and are widely used in fishing boats, electric ships, ferries, cruise ships, container ships, cargo ships, engineering ships, and other ships in China.
With the policy requirements for sustainable environmental development in China, it will become a trend for fishing vessels to switch from fuel powered to electric powered. From the current battery technology, it is most likely that lithium batteries will be used as fishing vessel batteries. So what kind of lithium battery is good for fishing vessels? Next, let's talk about which type of lithium battery is good for fishing boats based on its types?
Lithium batteries are classified according to raw materials, mainly including lithium iron phosphate batteries, polymer lithium batteries, and ordinary lithium-ion batteries. According to cell packaging, they are mainly divided into three types: cylindrical steel shell lithium batteries, soft pack
lithium batteries, and square aluminum shell lithium batteries
Lithium iron phosphate batteries have better performance than general energy storage lithium-ion batteries. They have high temperature resistance and the ability to discharge large currents at a certain rate. Ordinary lithium iron phosphate batteries have poor low-temperature performance, but improved lithium iron batteries have slightly better low-temperature performance than nickel hydrogen batteries and slightly worse than polymer lithium batteries, but their high-temperature performance will decrease. In terms of installation cost, lithium iron phosphate batteries are more expensive than nickel hydrogen batteries and lower than polymer lithium batteries. Therefore, most types of marine batteries currently used are lithium iron phosphate batteries, because using lithium iron batteries is more cost-effective in the same room temperature application.
Lithium iron phosphate batteries may vary in terms of performance and cycle life due to differences in production technology and materials used by manufacturers. Jinzhong Optoelectronics Factory has been producing and manufacturing lithium iron batteries for many years. The lithium iron phosphate batteries produced using proprietary patented battery formulas include three types: low-temperature lithium iron phosphate batteries, high rate lithium iron phosphate batteries, and conventional lithium iron phosphate batteries. A complete set of backup power systems can be designed and customized according to the actual application requirements of ship batteries.
After comparing the advantages and disadvantages of various types of lithium batteries used in ships, it is believed that many fishing boat owners should know how to choose the appropriate type of lithium battery based on their own ship's operating characteristics. Overall, lithium iron phosphate batteries are relatively good types of lithium batteries used in ships.
