Electric boat batteries, especially those from Hunan CTS, operate based on the principles of lithium - ion battery technology. At the core of these batteries are lithium - ion cells, carefully selected by CTS's experienced R & D team for their high energy density. When the electric boat is in operation, during the discharge process, lithium ions move from the negative electrode (anode) to the positive electrode (cathode) through an electrolyte medium. Simultaneously, electrons flow through the external circuit, generating an electric current that powers the boat's electric motor, enabling it to move through the water. A crucial component of CTS's electric boat batteries is the Battery Management System (BMS). The BMS acts as the control center of the battery, constantly monitoring and regulating various aspects of its operation. It ensures that the lithium - ion cells operate within safe voltage, current, and temperature ranges. For example, the BMS prevents overcharging, which can cause damage to the cells and reduce the battery's lifespan, and over - discharging, which can also degrade the battery's performance. When it's time to recharge the battery, an external power source, such as a shore - power connection or an onboard charger, supplies electrical energy. This energy causes the lithium ions to move back from the cathode to the anode, reversing the discharge process and replenishing the battery's energy. CTS designs its electric boat batteries with advanced thermal management systems. Since the marine environment can subject the batteries to varying temperatures, the thermal management system works to maintain an optimal operating temperature. This ensures the efficient and safe operation of the battery, maximizing its performance and lifespan. With strict quality control measures following ISO9001 and IATF16949 management systems, and international certifications, CTS's electric boat batteries provide reliable and efficient power for electric boating.
