Embodiment Construction

[0033] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered by the claims.

[0034] see figure 1 and figure 2 Freighters generally have a double bottom 1, which is used to ensure safety when the bottom of the ship is damaged, and its space is mostly used for ballast and fuel tanks, so a part that does not affect the navigation of the freighter can be used to store vanadium battery electrolyte 2. Part 1 of the double bottom used to store the electrolyte is lined with PE, that is, a protective layer is made on the inner wall of the ballast area as the electrolyte storage area with anti-corrosion polyethylene material to prevent the electrolyte from corroding the bulkhead. The part of the double bottom used to store the vanadium battery electrolyte is separated by multiple watertight bulkheads. If one of the bottom of the ship is da...

Abstract

The invention provides an electricity storage system of a vanadium battery cargo ship and a charging method. The system comprises a vanadium battery collocation room, a vanadium battery electrolyte storage area, a pump-in pipeline and a pump-out pipeline, wherein the vanadium battery electrolyte storage area comprises anti-corrosion buckets for separate storage of anode and cathode electrolytes; the anti-corrosion buckets are communicated with a double bottom ballasting area at the bottom of a cabin; an extraction opening of the pump-out pipeline is communicated with the bottommost part of theballasting area; the other end of the pump-out pipeline conveys the electrolytes to a shore-based liquid exchanging and charging platform through a connecting pipe; one end of the pump-in pipeline isconnected with a shore-based charging station; a liquid outlet is connected into an electrolyte bucket; the vanadium battery collocation room comprises a magnetic pump connected to the double bottomballasting area storing the electrolyte, and a vanadium battery pile set connected with the other end of the magnetic pump; an outlet pipeline of the vanadium battery pile set is communicated with theanti-corrosion buckets. The system makes full use of an idle space in the ballasting area; the influence of the electricity storage system on the carrying capacity of the cargo ship is reduced to thefull extent; a vanadium battery is adopted as an energy storage means for stable energy storage; quick charging is achieved in a manner of replacing the electrolyte of the vanadium battery.

Description

technical field [0001] The invention relates to the technical field of ship power supply, in particular to a vanadium battery freighter power storage system and a charging method. Background technique [0002] In order to meet the large power demand of cargo ships, the power of diesel engines continues to increase, and the fuel consumption continues to rise. The use of high-power diesel engines has caused increasingly serious environmental problems, such as the discharge of oily wastewater and fuel exhaust gas, which has deepened marine and air pollution. Serious environmental problems limit the further development of shipping, and the emergence of new energy ships is gradually solving the problem of ship fuel pollution. Ship power storage equipment is indeed a big problem: the charging time of lead-acid batteries is long, and the number of charge and discharge times is small; the price of lithium batteries is high, there are safety hazards, and it is not suitable for large-...
