Description
Technical field
The present invention relates to marine battery technical field more particularly to a kind of ship power supply units comprising iron liquid galvanic battery.
Background technique
Ship shipping is mostly important one of the mode of transportation of the mankind, is the prevailing traffic side of bulk supply tariff Foreign Transactions
Formula.It also brings a series of problems while shortening time, space and people is made to benefit from convenient and quick, for example, driving
The dynamic long-distance operation of ship needs to expend mass energy.Department of Transportation's statistical data in 2015 shows to be caused by marine fuel oil
Atmosphere pollution be only second to after motor-vehicle tail-gas and industrial discharge, rank third.And it is used in China in continent bank ship
Standard in terms of fuel oil is lower, and most ship is still using diesel oil or heavy oil inferior as fuel.And one with sulfur content
Ordinary diesel oil for 3.5% is the ship for driving fuel, is run one day, is discharged in exhaust gas, only SO2 emissions are with regard to phase
More than as Yu Ershi and is polluted caused by ten thousand trucies.In addition, the driving fuel that ship is carried with ship, once it leaks, it will be to sea
Foreign ontology brings very big pollution.According to statistics during 1973 to 2014, oil spill accident 3,000 occurs altogether for China coast
Yu Qi, wherein great oil spill accident has nearly hundred, total oil spillage reaches more than 40,000 tons.Based on this, International Maritime Organization is the 59th
Secondary environmental protection can on propose new ship energy efficient design index, the energy efficiency index be according to the greenhouse gas emissions of ship come
It measures, this is also the discharge amount for limiting ship carbon dioxide using enforceable legal document for the first time in the world.According to text
Part requirement, all new shipbuilding oceangoing ships had to comply with this new energy efficiency index from 2013.Restricted by this new policy and
Current environment destroys, the dual-pressure of energy crisis, becomes crucial solution channel as the green ship of power using new energy
An and general orientation of the following ship development.Green, environmentally friendly, low energy consumption new energy industry also have become the global traffic energy
The developing direction of transition.

For ship backup power source, life lighting power supply, fuel oil driving bring noise pollution can be effectively reduced and to close
Land area bring atmosphere pollution is the application field for having very much development potentiality.
Existing electric ship mainly includes pure electric vehicle and two kinds of combination drive.The former with secondary cell be pure driving force,
Without other auxiliary drive Force systems, and the latter is to combine other conventional ADS driving power such as secondary cell and fuel oil, natural gas, the two
Mutually auxiliary provides energy source and power for ship.And the secondary cell of the ship of existing report mainly has ferric phosphate lithium cell, nickel
Hydrogen, fuel cell and all-vanadium flow battery etc..
Chinese patent CN207956016U discloses a kind of Ni-MH power cell Electrical Propulsion Ship, is made with nickel-metal hydride battery
For ship power, although nickel-metal hydride battery has the advantage of high current work, its own energy density and cost do not have simultaneously
Advantage.Nickel-metal hydride battery is developed from nickel-cadmium cell, although cycle-index can support high current charge-discharge up to 1000 times,
But have self discharge after there is full charge, there are memory effect, cryogenic property is good but high-temperature behavior is poor, at high cost
The shortcomings that.
Chinese patent CN102358412B discloses watercraft electric propulsion system and its implementation of a kind of multi-energy hybrid power
Method, uses multiple-energy-source combination drive ship, and the power source of use includes power battery, solar energy, fuel engines, and three
Person cooperates under the various process different situations of vessel motion, provides the energy for ship.Although using dynamic in patent use
Power battery, but which kind of battery system indefinite is, only constructs multi-energy hybrid power system and operating scheme.
Chinese patent CN104950718B discloses a kind of hybrid power ship electrical and mechanical comprehensive information monitoring method and device,
Ship is driven using hybrid power, hybrid power includes that power battery and liquefied natural gas generate electricity two kinds, coordinates work by the two
Driving force is provided as ship.The calculating of its real-time cruising ability for focusing mainly on two kinds of driving forces, and obtained by calculating
Information control effectively to the Mechatronic Systems of ship, more detailed discussion is not made to power battery.
Chinese CN106129444A discloses a kind of pure electric vehicle ship profession all-vanadium flow battery, protects the all-vanadium flow
Battery structure and main material.But is forbidden influencing of both the import of vanadium waste material, steel new standard by country in the recent period, cause complete
Vanadium redox flow battery electrolyte raw materials for production price rises, and stabilizing for cost of material needs a process.Therefore, cause full vanadium liquid
Galvanic battery cost reduces insufficient space.Although in addition, all-vanadium flow battery than lithium ion battery have higher safety,
When for ship driving force, there are still the risks that difficult recycling after V electrolyte leakage after accident occurs for ship, to water where ship
It is unfavorable that body generates.
But currently, and having no that any report applies iron liquid galvanic battery as ship power battery, backup power source etc..
