China launches a ship equipped with a hybrid installation with lithium-ion batteries

Shenhai 01 (Deep Sea 01) patrol and rescue vessel launched in China, the first ship in China with an electric power plant with lithium-ion batteries. The ceremony was held on April 28, 2020 in Guangzhou at the Chinese shipyard Huangpu Wenchong Shipbuilding Company Limited, reports the bmpd blog.


Reportedly, the ship was built by order of the Shenzhen Maritime Administration to ensure the safety of wiring gas carriers. The contract for the construction of the vessel was signed in 2018, the transfer of the vessel to the customer is scheduled for this year.

Among the tasks of the new ship are patrolling and pilotage, monitoring the safety of approaches to the port of Shenzhen, monitoring the sea and air conditions and emergency rescue operations.

The total displacement of the vessel is 1450 tons, length - 78 m, width - 12,8 m and draft - 5,5 m. Crew 60 people. The ship is equipped with underwater remotely controlled vehicles, there is a helipad. Speed ​​18 knots, cruising range - 1000 miles.

A hybrid electric power plant is installed on the vessel, which includes three diesel generators with a capacity of 2080 kW each and two propeller-thruster columns with electric motors, as well as two groups of lithium-iron-phosphate batteries of the declared capacity of 750 kWh. Electric motors are powered by rechargeable batteries, which are charged from diesel generators.

    What's the point? Save fuel in traffic jams?

      ========
      Rather, the development of new technologies. The Japanese are already building diesel-electric submarines with lithium-ion batteries - they have 4 times more capacity than lead-acid ones, but there are problems - they are fire hazardous - they are prone to spontaneous combustion. The Japanese seem to have somehow solved this problem ..... Now it seems that the Chinese are trying to catch up with them, but they didn’t dare to put the LIA on the submarine - so they decided to try it first on a surface ship.
      But this is just my personal guess ....

      Apparently, to prevent sparks from the exhaust pipe to the gas carrier.

    Only capacity is not measured in kilowatt hours, but in ampere * hours.

      In ampere hours it’s like in parrots ... It does not carry any information.

        If it had not carried information, then it would not have been measured in amperes / hours. But, for some reason, they measure it.

      Yes, in ampere * hours, but then it will be necessary to write voltage. And here they have already moved from separate values: current strength and rated voltage to their product, i.e. to power.
      The author of the article himself did not come up with the characteristics, but took them from somewhere, so he put what was.

        Yes, you are probably right. Only 750 kWh it turns out about 1000 hp in an hour? And then all the batteries? And why is this necessary? I think in a German submarine of the PMV model, batteries were better.
        So there is clearly something wrong with the units. Probably 750 megawatts.

    and what's the point of such a strange power plant
    OK, the PLO ship would be, the electric ship when searching for the submarine, but for such a patrolman, why?
    They are not cheap.

      Yes profit shaft:
      1) It will monitor the atmosphere = this is best done when you do not smoke with your diesel engine.
      2) He needs the maneuverability of the tug, so instead of the valines, he has 2 helical columns + a steering column in the nose, all on electric motors.
      3) Development of technologies for the new generation of 056 corvettes and new frigates with 8 nodal strokes under electricity, without diesel engines. Like all Koreans, French and others.

        1. And before that, how was it monitored? Is the price too much for this “better”?
        2.
        he has 2 helical columns + a steering column in the nose, all on electric motors.

        Batteries are not needed for this.
        3. The electric ship for the PLO is the right thing. Only this is not PLO.
        And who prevents you from doing this on the corvette right away, which is much more logical
        He will perform his functions with batteries and without, and you can actually check the result.
        And here are completely different modes.

        Perhaps for maneuvers it is necessary to give out high power for a short time (many times more), but in the rest of the time such power is not needed?
        Then they saved on the power of the main unit and on fuel consumption at the twentieth.

        Again, this all makes sense with active use, but for the Chinese this is probably not a problem.

    Meaning? The only thing is to work out such a technique for the interaction of equipment for use in submarines. To use electric motors as the main ones in the box, batteries are needed. Next up are the chargers, the electronics that will track the modes. Further. Batteries are not current sources. These are drives. That is, first they need to be charged. And this is a multiple conversion of energy, which reduces the overall efficiency of the system. And seriously. A battery having its own efficiency of 80% is inserted into the system. If you take into account the charging efficiency, this is another 90%. General, already 80 * 90 = 70% And this is without taking into account ICE, gearboxes and other mechanisms. The traditional ones have no such losses. Well, and cherry- PRICE. Here, perhaps, you need to double the cost of the propulsion and charging installation.

    Tractors with a diesel-electric drive have some advantages - there is no battery, but a smooth ride under load does wonders. The start is much more gentle, without violence over the structure.

      do you think now on the submarines otherwise somehow?

      Why is it needed for a ship of this purpose?

    The Chinese have developed a new technology. Blade Battery. When driving nails into the case, the temperature of the LIAB reached 400 degrees C, then the temperature of the above battery did not exceed 60 degrees.
    Other tests (for bending, sawing, heating to 300 degrees Celsius, reloading by 260%,) also failed to ignite the battery.

      When driving nails into the case, the temperature ... of the above battery did not exceed 60 degrees.
      Other tests ... also failed to ignite the battery.

      In the old part we had a "mushroom of honor", to which hundreds of phones, smartphones and other non-standard gadgets were pinned. And for some reason, none of them caught fire.
      And the Chinese are still bouncers in attributing to themselves achievements and discoveries from scratch.

    Well, well done, everything about the case, approval, although, for China, adequacy is rare.request

    Do you think that such issues have already been resolved, and there is no longer room for perfection? There are attempts to use, but China is new. Sometimes you have to work it yourself, you can smoke, but it doesn’t work out.

    They have nothing there. Go to another chemistry, well known to everyone .... All questions on the use of one type or another, to an accountant, these are price questions. FOR UNIQUE SYSTEMS YOU CAN GO FOR COSTS.

    But within the rules of electrical engineering. If there is a desire to measure in elephants, then you need to measure in them. And this is another unit of measure - talking about the energy stored in the battery. But, not capacity. Here it is, dear, measured in kilowatt hours.

    Interesting idea. But it’s not clear where the gain is? Short-term afterburner. For a rescue ship. Have on board a mass that doubles the main engine, using parallel operation in exceptional cases. Synchronizing devices, loading both ICE and electric motors equally. For such work, it is always necessary to identify and install devices that play the role of master and slave, so that they do not overtake each other. This is almost the same thing I just wrote about. Although, their role is different. Have you tried to work under the leadership of two team leaders at the same time? Or two directors? And How? Why do you suggest the steamer do this?

    You are mistaken. It is not possible to believe that this was in the original source. Most likely, YEGESHNIKI-parcharchi with incomplete secondary education and not begun higher education write such nonsense.

    What are you? This is the power of the nuclear reactor of the Chernobyl nuclear power plant. And even more.
