company news about 3. Safety and maintenance of lithium batteries for yachts

Lithium batteries are a new type of energy storage device with advantages such as high energy density, high charging and discharging efficiency, long lifespan, and environmental protection. They have been widely applied and promoted in the field of yachts. However, lithium batteries also have some safety hazards, such as overcharging, discharging, short circuit, impact, puncture, etc., which may cause thermal runaway or combustion of the battery, and even lead to serious accidents such as boat fires or sinking. Therefore, when using lithium batteries on yachts, the following points must be noted:
Choose the appropriate type and specification of lithium battery. According to the power demand and space conditions of the yacht, select the appropriate type and specification of lithium battery, such as lithium iron phosphate battery, ternary lithium battery, polymer lithium battery, etc. Different types of lithium batteries have different performance and characteristics, and need to be matched according to the specific situation of the yacht. For example, lithium iron phosphate battery has high safety but low energy density; Ternary lithium batteries have high energy density but low safety; Polymer lithium batteries have a small volume, but their energy density is also 1% lower.
Use a qualified charger and charge and discharge management system. In order to ensure the safe charging and discharging of lithium batteries, it is necessary to use a qualified charger and charging and discharging management system (BMS), and correctly connect and operate according to the instructions. The charger should match the type and specifications of the lithium battery to avoid overcharging or undercharging. BMS should be able to monitor the temperature, pressure, voltage, current and other parameters of lithium batteries in real-time, and timely balance, protect, and alarm.
Avoid mechanical or environmental damage to lithium batteries. Lithium batteries should avoid mechanical damage such as impact, puncture, compression, and twisting during use or storage to prevent internal short circuits or liquid leakage. At the same time, lithium batteries should be avoided from being exposed to environments such as high temperature, high humidity, strong light, and strong magnetism to prevent affecting their performance or safety.
Regularly inspect and maintain lithium batteries. In order to extend the service life of lithium batteries and ensure their safety performance, regular inspections and maintenance of lithium batteries should be carried out. During inspection, attention should be paid to whether there are abnormal phenomena such as deformation, cracks, and expansion on the appearance of the lithium battery, as well as whether the connecting wires are loose, broken, or oxidized. During maintenance, the surface and connectors of the lithium battery should be cleaned, and necessary charging and discharging operations should be carried out according to regulations.
In short, when using lithium batteries on yachts, attention should be paid to selecting the appropriate type and specification, using qualified equipment and systems, avoiding damage and impact, and conducting regular inspections and maintenance. Only in this way can safety and comfort be ensured on the yacht.
