Description
Technical field
The present invention relates to a kind of replacement battery systems and method for changing on-vehicle battery capacity for electric car dynamic, will
It changes power mode to combine with charge mode, power mode will be changed and be used to dynamically change on-vehicle battery capacity, to adapt to personalization
Demand；And it is electrically separated by vehicle, accident risk is reduced, realizes to the irregular care and maintenance of battery, belongs to electric car
The technical field of system design.
Background technique
All the time, the electric energy supply of electric car is a stubborn problem.To improve service performance and promoting convenience
Property, the technological means used in existing application mainly includes two, i.e., rapid nitriding and changes power technology (replacement battery skill
Art, such as reference 1).Above two technological means has certain requirement for the construction of infrastructure；And its emphasis
It is all to be to promote the convenience of electric energy supply, do not solve the problems, such as individual demand fundamentally.
For the passenger car with strong individual demand feature/home vehicle field, major demands include:
1, routine short distance travels demand: average daily mileage travelled is shorter, and usually 50-100 kilometers；To the requirement of battery durable mileage
It is lower；
2, intermittent long-distance running demand: within the period of certain Relatively centralizeds, there is the demand of long-distance running, including go on business,
Travel, visit kith and kin etc.；It is more demanding to battery durable mileage；
It can be seen that the core of above two demand difference is that have different requirements to the capacity and characteristic of battery, therefore it is simple
The convenience for promoting electric energy supply can only treat the symptoms, and cannot effect a permanent cure.
With the development of power battery technology, perhaps can be equipped on electric car in the near future can continue a journey
500 kilometers of mileage or more of battery, it is shorter for average daily mileage travelled although mileage anxiety can be solved substantially in this way
For passenger car, great resources idle and waste will be also caused.Moreover, the environment of electric car is relatively complicated and dislikes
It is bad, therefore it is stored in the power battery among electric car for a long time, calendar life can also shorten very much, significantly lower than battery
In the theoretical service life, this also just necessarily aggravates the degree of the wasting of resources.When course continuation mileage increases, the charge frequency of vehicle mounted dynamic battery
It reduces, even if theoretically still thering is certain cycle-index can use using 8-10, but actually locating for electric car
External environment is complicated and changeable, if without reasonably conserving whether on-vehicle battery can adhere to using 8 years being all unknown, and retired
Remaining battery later can directly utility value also remain little.
There are also a bit, many accidents of electric car occur in the period of parking at night, especially carry out night
In the case where charging.Since night management difficulty is big and is not easy to find the problem in time, often lead to accident upgrading cause it is serious after
Fruit.When the quantity of on-vehicle battery increases, the probability for inducing accident is also increased.
Although there is many people to support " changing power mode ", the drawbacks of " changing power mode " still it is clear that
First is that " changing power mode " needs a large amount of battery reserve, it is more difficult that investment is high, industry size is huge, industrial chain is coordinated；
Second is that " changing power mode " will increase the unstability risk of battery Yu electric car connection structure, cause safety problem, and
And frequently dismounting cell can generate mechanically deform or damage.
Therefore, " changing power mode " is suitble to the group users such as taxi, bus and the unit that has fleet and in bus
There have been many successful cases in field；And " charge mode " is more suitable for the casual households such as passenger car/home vehicle, for the purpose of electric energy supplement
" changing power mode " be not appropriate for such application.
Reference:
1, Chinese patent: application number 2016108904412, for electric car chassis type electrical changing station and its change method for electrically.
Summary of the invention
In view of the prior art the problem of, the technical scheme is that, power mode and charge mode knot are changed by existing
Altogether, the purpose for replacing battery is no longer electric energy supplement but dynamic changes on-vehicle battery capacity, to adapt to personalized need
It asks；And it is electrically separated by vehicle, accident risk is reduced, is realized to the irregular care and maintenance of battery.
The replacement battery system for changing on-vehicle battery capacity for electric car dynamic of the invention, including fixed battery
Group, replaceable battery group, and the first reserved space corresponding with fixed battery pack, replaceable battery group and second are reserved
Space；It is specific:
First, the reserved space for installing battery is preset in electric car；
Second, battery is divided into fixed battery pack and replaceable battery group, reserved space is divided into first accordingly and is left a blank in advance
Between and the second reserved space；
Third, in the production process of electric car, by fixed battery pack (static state) be installed among electric car first in advance
Among spacing, then with electric car it connect and fixes；Second reserved space is idle state；At this point, being by fixed battery pack
Electric car provides electric energy, for meeting short distance traveling demand；
4th, when needing to meet long-distance running demand, replaceable battery group (dynamic) is installed among electric car
Among two reserved spaces, then with electric car it connect and fixes；At this point, being jointly electricity by fixed battery pack and replaceable battery group
Electrical automobile provides electric energy, for meeting long-distance running demand；
5th, after long-distance running demand, replaceable battery group is taken out among electric car；Second reserved space
Revert to idle state；At this point, electric energy is provided by fixed battery pack for electric car, for meeting short distance traveling demand.
It should be pointed out that the short distance traveling one way distance is associated with the fixed battery capacity of battery pack；It is described
Long-distance running one way distance it is associated with the battery capacity summation of fixed battery pack and replaceable battery group.
Further, the fixation battery pack uses iron phosphate lithium positive pole battery or lithium manganate cathode battery；Its advantage
Be security performance is higher, the complicated applications environment that is adapted to electric car, the disadvantage is that energy density is relatively low；Due to fixed battery pack
It is chronically within electric car, therefore should preferentially select the higher battery types of security performance.Also, fixed battery pack is only held
Lesser part in battery total capacity is carried on a shoulder pole, therefore the relatively low weakness of energy density is not to protrude very much.
Further, the replaceable battery group is using ternary material positive battery or the electricity of other high-energy densities
Pond；For meeting long-distance running demand.
It should be pointed out that replaceable battery group particularly may be divided into two kinds, one is reserve batteries, i.e. battery to be purchased by user
It buys and holds property right；Another kind is shared battery, is uniformly purchased by operator, and user, which leases, to be used.
The service that temporarily in commendam, maintenance, maintenance, charging are provided for reserve battery operator, when by keeping
Between valuate and by charge capacity valuate；The lease service provided for sharing battery operator, valuates by lease time；To shape
At two different profit models.
It further, include battery identity authentication module in replaceable battery group, for confirming the identity of battery and being used for
The use process of record and tracking replaceable battery group.
Advantages of the present invention:
1, the more selection schemes of user are given, is conducive to carry out shared battery mode, reduces the overall usage amount of battery, raising makes
With rate, reduce resources idle and waste；
2, significant for the short distance traveling higher passenger car/home vehicle of demand accounting；Accounting for about total kilometres 70-80%
Short distance driving mode under, the total weight of electric car mitigates, and is beneficial to energy conservation；The number of on-vehicle battery in most of the time simultaneously
It measures less, accomplishes that vehicle is electrically separated to a certain extent, reduce the risk that safety accident occurs；
3, fixed battery pack and replaceable battery group can more have the carry out type stressed and characteristic to select and carry out mashed up, fill
Divide the individual demand for meeting user；Short distance traveling uses the preferable phosphorus of comprehensive performance after exclusion energy density factor
Sour iron lithium positive battery or lithium manganate cathode battery, safety and durability are all protected；Long-distance running mainly uses energy
The higher ternary material positive battery of density, thus the performance of long-distance running also it is available ensure, simultaneously replaceable battery group
The regular carry out maintenance off-line of meeting, service life and safety will also be promoted；
4, user is released to a certain extent to the distrust problem of replacement battery mode, because occurring when to replaceable battery group
When failure or problem, system, which can alarm and be rapidly switched to relatively safer fixation battery pack, provides electricity for electric car
Power, and it is unlikely to the serious consequence that runs out of steam or cause completely；
5, electrically operated purpose of changing of the invention is to change on-vehicle battery capacity, the use less for most of long-distance running demands
Family, the frequency of replacement operation are usually less than 30 days/time；The lease intention of user is more clear as a result, can be by reserving in advance
Mode, improve the operational efficiency of operator；Also, the frequency that electricity is changed by reducing, so that operator and user can connect
It is changed the electric time by longer and (is not also repelled fast quick change power technology certainly), thus have more sufficient time to replaceable battery group
It carries out tightened up fixation and verification, realize safer and firm connection, and the mechanically deform after longtime running can be corrected
Etc.；
6, the major function as the electrical changing station of the dispersed placement of auxiliary facility is to carry out battery altering and change vehicle mounted electric pool capacity
Amount, is detected and is maintained to the battery replaced, and it is not absolutely required to battery electric energy supplement, therefore electrical changing station
Cost decline to a great extent, safety it is also higher.

It as shown in Figure 1, 2, is the batteries of electric automobile assembling scheme of existing scheme；Battery 10 is fixed on chassis 5.
As shown in Fig. 3,4,5,6, the technical solution of power mode is changed for chassis of the invention:
The structure type that the replacement of replaceable battery group 2 is replaced using chassis, the second reserved space 4 are set to electric car 9
The intermediate region on chassis 5, so that the position of centre of gravity of replaceable battery group 2 and the position of centre of gravity of electric car 9 essentially coincide；
Replaceable battery group 2 is fixedly mounted on detachable bottom plate 6, then is connect simultaneously by detachable bottom plate 6 with chassis 5
Position fixed, that replaceable battery group 2 is installed to the second reserved space 4 simultaneously；
As shown in Figure 3,4, when replaceable battery group 2 is taken out from electric car 9, in addition prepare the detachable of a blank
Bottom plate 6 is installed to the corresponding position of the second reserved space 4, plays the role of sealing；
It as shown in Figure 5,6, should be first by corresponding position when needing for replaceable battery group 2 to be installed among electric car 9
The detachable bottom plate 6 of blank takes out.
Embodiment 2:
The present embodiment introduces electric car and charges/change electric network system and its operation method.
Electric car charges/changes electric network system, is based on the replacement battery system for using dynamic to change on-vehicle battery capacity
The electric car of system and establish, be used to replace the electrical changing station 7 of battery including several, the process of the replacement battery is changing electricity
It stands and 7 completes, electrical changing station 7 includes the combination of one or both of centralized electric charging station 7a, distributing electrical changing station 7b, in which:
Battery charging/discharging center, battery replacement device, scheduling batteries device are included at least in centralized electric charging station 7a；
Battery replacement device, battery check device and battery maintenance device are included at least in distributing electrical changing station 7b.
Device used in above-mentioned centralized electric charging station 7a and distributing electrical changing station 7b is the prior art, in addition
The technical solution of electricity can also be changed using movable type.
Further, the site-choosing principle of centralized electric charging station is traffic convenience and close electrical network access point (such as power transformation
Stand), cost is advantageously reduced in this way, is improved efficiency.But in the prior art, it is difficult to carry out addressing by mentioned above principle, because concentrating
There are some contradictions for the addressing of formula electric charging station 7a:
If reduced to the convenience of automobile user using charge mode and to establish large-scale mating parking
Field and charging pile；
If needing to lay in a large amount of reserve battery, investment is excessively high, and resource utilization is lower using power mode is changed.
Electric car of the invention charge/the change operation method of electric network system specifically includes following two, two kinds of operations
Method can be used alone or combined application:
The first, electric charging method is concentrated: including one or more centralized electric charging station 7a；
When electric car 9 is when following a period of time is in stopping or short distance driving status, electric car 9 goes to centralization to fill and changes
Replaceable battery group 2 is disassembled from electric car 9 by battery replacement device, then passes through scheduling batteries by power station 7a
The feeding of replaceable battery group 2 battery charging/discharging center is managed collectively by device；It is filled at this point, electric car 9 leaves centralization
Electrical changing station 7a can travel a distance and stop into run-stopping status or continue short distance traveling；
Centralized electric charging station 7a is gone to when electric car 9 has long-distance running demand, it will be replaceable by scheduling batteries device
Battery pack 2 is taken out from battery charging/discharging center, then replaceable battery group 2 is installed to electronic vapour by battery replacement device
Among vehicle 9；At this point, electric car 9 leaves centralized electric charging station 7a, and long-distance running can be carried out；
The second, method for electrically is changed in dispersion: including several distributing electrical changing stations 7b；It (can be according in geographic area and region
Electric car liveness is uniformly distributed)
Distributing electrical changing station 7b is gone to when electric car 9 has long-distance running demand, then passes through battery replacement device for distributing
The replaceable battery group 2 stored in electrical changing station 7b is installed among electric car 9；At this point, electric car 9, which leaves distributing, changes electricity
Stand 7b, and can carry out long-distance running；
When electric car 9 is not when having long-distance running demand following a period of time, electric car 9 goes to distributing electrical changing station 7b,
Replaceable battery group 2 is disassembled from electric car 9 by battery replacement device and is stored in distributing electric charging station 7b
Among；Distributing electrical changing station 7b is detected and is protected to replaceable battery group 2 by battery check device and battery maintenance device
It supports；At this point, electric car 9 leaves distributing electric charging station 7b, short distance traveling is carried out.
Further, since the storage volume of each distributing electrical changing station 7b is limited, it is therefore desirable to by dispatching buses 8 pairs
Replaceable battery group 2 is scheduled management, specific:
The first, Decentralization (as shown in Figure 7): by a part of replaceable battery in the distributing electrical changing station 7b of amount of storage saturation
Group 2 is taken out, is put into and dispatches buses 8,8 replaceable battery group 2 is transported to the insufficient distributing electrical changing station of storage by dispatching buses
It is stored in 7b；
The second, United Dispatching (as shown in Figure 8) is carried out by centralization electric charging station 7a: the distributing that amount of storage is saturated is changed into electricity
A part of replaceable battery group 2 in 7b of standing takes out, is put into and dispatches buses 8,8 is transported replaceable battery group 2 by dispatching buses
It is stored to centralized electric charging station 7a；Meanwhile a part of replaceable battery group 2 is taken out from centralized electric charging station 7a and is put into tune
Vehicle 8 is spent, 8 replaceable battery group 2 is transported in the insufficient distributing electrical changing station 7b of each storage stores by dispatching buses.
It should be pointed out that the replaceable battery group 2 sent out from distributing electrical changing station 7b is with the insufficient battery of power margin
It is preferential；The replaceable battery group 2 sent out from centralized electric charging station 7a is usually fully charged.Also, user is from distributing
The replaceable battery group 2 obtained at electrical changing station 7b is not necessarily fully charged state, and user can voluntarily select more economical fill
Electric mode, such as in the way of the charging of the paddy electricity of household charging pile etc..
Two application cases are lifted below to be illustrated.
First, by taking the application (average daily mileage travelled is shorter) of private car as an example:
Firstly, (can also be by it by 1:2 configuration by the battery capacity ratio of the fixation battery pack of private car and replaceable battery group
He configures)；
In a shared mode, replaceable battery group is not bought when user buys electric car, and only purchase meets short distance traveling demand
Fixation battery pack；When user has long-distance running demand, then replaceable battery group is temporarily rented from shared battery operator.
Assuming that there is 80% private car user to select shared model.The replaceable battery laid in needed for shared battery operator
Group quantity, which carries out deposit in 40% ratio of number of users, can meet application demand.
The time that replaceable battery group is rented in the annual of private car user is about 40-100 days, i.e., based on 60 days average
It calculates；It is short distance traveling there are about 80% mileage travelled；
Assuming that replaceable battery group price is 60,000 yuan, calculated by service life 10 years, then user buys the personal feelings of power battery
Under condition, conversion to need to pay 6000 yuan every year；Wherein, do not figure interest factor, also not include battery not to service life
Decaying or damage are led to the problem of, actual use cost is much higher than 6000 yuan/year.
According to shared battery mode, battery operator is shared in 40% ratio and carries out battery reserve, i.e., for each service
Investment in terms of object reserve cell is 2.4 ten thousand yuan；Private car user rent replaceable battery group price fixing be 80 yuan/
It, then user year payment expense is about 3200-8000 member, 4800 yuan/year of average out to；User has enjoyed good service, does not have to
The problem of worrying cell decay or damage, expense aspect is substantially also within the scope of acceptable.
It should be pointed out that a large amount of replaceable battery groups will be in the spare time in the period of long-distance running demand is at a low ebb
State is set, the replaceable battery group that would sit idle for organizes the application for energy storage peak shaving.
For the investment payback time for sharing battery operator taxi battery is about 5 years；Meanwhile replaceable battery group is flat
Idle number of days is about (365-60/40%)=215 day, in these periods, the replaceable battery group tissue that can would sit idle for
Get up to be used for other application (application of such as energy storage peak shaving).
Therefore on the basis of in view of other investments of centralized electric charging station and distributing electrical changing station etc., battery is shared
The overall investment payoff period of operator can control at 4 years or so, and the adequate service life of replaceable battery group can then reach
By 8 years or more.
Compared with legacy user buys the personal mode of battery, the battery of the present invention program uses total amount are as follows:
1- (2/3* (100%-40%)) * 80%=68% can at least save total usage amount of 32% battery, save society's money
Source, the popularization for being conducive to electric car；Total usage amount of battery is reduced, it is meant that the overall vacancy rate of battery reduces, Ke Yigeng
Good coordination circulating battery number and the unmatched contradiction of calendar life.
In conclusion service efficiency is improved, so that user and operator can obtain by the total usage amount for reducing battery
Obtain good income.
Second, by taxi, logistic car application (average daily mileage travelled is longer) for:
In daily normal course of operation, the quick charge of existing scheme or the electric energy additional project of fast quick change electricity can be continued to use；
It, can be by electric automobile during traveling at electrical changing station 7, by replaceable battery group 2 from electronic vapour after daily operate normally
It disassembles and is stored among electrical changing station 7 in vehicle 9, carry out maintenance and electric energy supplement；It is changed at this point, electric car 9 can sail out of
Power station 7 arrives at the destination rest by short distance traveling；
When next day operating normally beginning, is travelled through short distance after a period of time and drive to electric car 9 at electrical changing station 7, it will
Replaceable battery group 2 in electrical changing station 7 from taking out and be installed among electric car 9；At this point, electric car 9, which can sail out of, changes electricity
It stands 7, starts normal long-distance running process.
Electrical changing station 7 described in above scheme can be centralized electric charging station 7a or distributing electrical changing station 7b, this time-division
Dissipating formula electrical changing station 7b also has the function of charging.
The advantages of program, is:
Electrical changing station need not build matched parking lot and charging pile and addressing is more flexible, to reduce cost；Even if certain
Have matched parking lot in park for vehicle concentration, need not also establish matched charging pile, and stoppage in transit when
Between section accomplish that vehicle is electrically separated substantially；
Substantially without the investment in terms of battery reserve, construction cost further decreases electrical changing station；
Electrical changing station is charged using off-line type, paddy electricity can be made full use of to charge；
Electric car still has certain distance travelled, does not influence the use in the short time after by the unloading of replaceable battery group；
Accomplish that vehicle is electrically separated and can reduce many things without charging substantially in the period that electric car is stopped transport
Therefore hidden danger, each electric car can be with the convenient parking positions of unrestricted choice.
It is pointed out that electric car 9 longer for average daily mileage travelled, mileage required for dealing electrical changing station 7
The several and time will not become very big burden.
The invention is not limited to above embodiment, and those skilled in the art are smart without prejudice to the present invention
Equivalent deformation or replacement can be also made under the premise of mind, these equivalent variation or replacement are all contained in the claim of this application institute
In the range of restriction.
