Description
Technical field
The utility model is related to electric automobile, and in particular to the electrokinetic cell bag active safety that a kind of electric automobile is used is prevented
Protecting system, belongs to electric vehicle engineering field.
Background technology
With the continuous sternness of world energy sources form, without using the new energy car of traditional fuel more and more by everybody institute
Advocate and encourage.Wherein electric automobile turns into the emphasis direction of Corporation R ＆ D, and is answered as the development of technology also achieves business
With progressing into the life of people.Although electric automobile realizes that road is travelled already, the problem of it is faced is also a lot, this
It is to cause the major reason of its slower development, most important of which restraining factors are exactly electrokinetic cell.Current driving force battery is main
There is following defect：1st, cost remains high, and accounts for more than half of integral vehicle cost；2nd, endurance is weak, even if common batteries fill
Full electricity can only also travel 200-300 kilometers, and with the increase of charging times, course continuation mileage can also be reduced constantly；3rd, battery
Charging is inconvenient, and otherwise much layout densities not as good as current gas station, and have certain requirement to charging ambient temperature can
Influence battery life；4th, short life, the life-span of electrokinetic cell is usually 5-6, needs to buy new electrokinetic cell after scrapping, and
Its is expensive, and consumer is difficult to bear；5th, the charging interval is long, is also required to more than half hour even if filling soon, with traditional oiling
Oiling of standing still seems very slow, and it is shorter to fill course continuation mileage soon；6th, different car enterprises, the battery specifications difference of automobile type configuration, often
It can not exchange, higher requirement is proposed to cell production companies and vehicle manufacturer, while also improving automobile research
Cost；It is identical with a car battery configuration, consumer can not according to itself actual driving situation it is personalized adjust.7th, in order to right
Battery operating regime is monitored, and existing electric automobile is configured with BMS management systems to electrokinetic cell, and BMS management systems are used for
The important informations such as voltage, electric current and the temperature of battery are monitored, these information are stored in BMS management systems, it is necessary to which special sets
Standby to read, user is not equipped with such equipment therefore can not understood.
Current market is mostly rechargeable or by the whole electricity of guaranteeing replacement of large-scale accessory machinery.No matter that mode, above-mentioned
Defect is all more or less present.To solve the above problems, prior art occurs in that the electrokinetic cell bag of blocking, electrokinetic cell
Wrap as modularized design, be standard component, the electric automobile of all manufacturer productions can be used, simply the production of different cars enterprises is not
Different with series-parallel system with the quantity of vehicle electrokinetic cell bag, this is according to power of vehicle size and course continuation mileage needs
It is fixed.The all problems of the foregoing electric automobile pattern can nearly all be solved to a certain extent, greatly reduce electrokinetic cell
Construction cycle and cost, due to single electrokinetic cell bag light weight, can carry out and change electrically manually, greatly save and change electricity and set
Standby high cost input, simultaneously because battery bag is minimized, can realize that automobile development electrokinetic cell unit is standardized, unify dynamic
Power battery bag model, even if vehicle, technical indicator are different, only need to increase or change in these " standard components "（That is electrokinetic cell bag）'s
Quantity and series-parallel system are that can be achieved.But due to the characteristic of electrokinetic cell in itself, its output remains as high pressure, so as electricity
The connection of potential source and other devices on vehicle, and the oneself safety protection in the case where there is fortuitous event, compared to traditional fuel oil
For engine, electric automobile this respect requires some higher, once it is inadequate electric leakage, insulation occur, it will to passengers inside the car and
Vehicle brings severe safety hazards.
