Problems solved by technology

However, the limitation of battery capacity leads to high manufacturing cost, long charging time, short battery life, and low redundancy. It is still difficult to meet the actual needs at present.
Moreover, due to the influence of power generation methods, power density and energy storage technology, pure electric ships at this stage cannot achieve high-performance speed, acceleration and self-control, and their battery life is also restricted by their battery capacity. Provide continuous energy output, but the traditional power grid diesel generator sets have low power generation efficiency at a constant speed, and they are in low-load conditions for a long time, resulting in serious waste of fuel
[0004] The reduction of petroleum resources makes it difficult to meet the needs of traditional diesel engine propulsion. On the other hand, diesel engine propulsion has the disadvantages of high emissions and high pollution. Although measures such as installing after-treatment devices and optimizing fuel injection can improve emissions, it will be difficult to meet more stringent requirements in the future. Although the pure natural gas engine or dual-fuel engine propulsion can greatly reduce the emission of sulfur and nitrogen compounds, it is still difficult to solve the problem of CO 2 Emissions problems, and natural gas engines have shortcomings such as poor low-working conditions and insufficient torque loading, and there are obvious deficiencies in power performance. Traditional ship waste heat utilization can improve part of the efficiency, but the waste heat system for the hybrid power field has not been studied, and integration is difficult. No mature technical solution
