Description

Extensible pluggable interface battery pack and plugboard of battery power machine

Technical Field

The invention is applied to the field of machinery adopting pure battery power or hybrid battery power, and is particularly applied to the industries of electric automobiles, electric bicycles, electric motorcycles, other electric passenger vehicles and electric unmanned aerial vehicles.

Background

In recent years, the new energy automobile industry in China is in a situation of increasing production and sales volume year by year under the promotion of various government superposition policies, and the production and sales of new energy automobiles are nearly 80 thousands in 2017. However, new energy automobiles have also reached an endless difficult year, and the problem of limited driving range is mainly faced. The driving range of the electric automobile used in the market after once charging is generally 100-300km, and the number is generally ensured only by keeping a proper driving speed and having a good battery regulation system, while the driving range of most electric automobiles in a general driving environment is only 50-100 km. Compared with the traditional fuel oil automobile, the power supply is the technical bottleneck of the development of the new energy automobile, and the short driving range of the electric automobile becomes the fatal weakness of the electric automobile. The cruising distance depends on the capacity of the vehicle-mounted battery, which has the following disadvantages:

1. and the size and the quality of the storage battery. The batteries used in the existing electric vehicles cannot maintain reasonable size and mass on the premise of storing enough energy. If the electric automobile is large in self-equipment mass, the acceleration performance and the maximum speed can be influenced. For example, the external volume of the existing battery of the electric automobile is generally up to 550L, and when the battery with the large volume is used on a family car, the space of a trunk of the car is inevitably occupied.

2. The battery life is too short. The storage battery has short service life and can be replaced in several years. The charge and discharge times of the ordinary storage battery are only 300-400 times, even the charge and discharge times of the storage battery with good performance are 700-900 times, the service life of one storage battery is at most 4 years calculated according to 200 times of charge and discharge every year, and the service life of the storage battery is too short compared with that of a fuel automobile.

3. Electric vehicles are expensive. The battery technology is complex, the cost is too high, and the manufacturing cost of the electric automobile is high due to the adoption of a series of new materials and new technologies. The price of the storage battery of the electric automobile is about $ 100/kW.h, and even some storage batteries are as high as $ 350/kW.h, so that the cost is too high to bear by users. In 2023 years after six years, the cost of replacing one battery is about 0.94 ten thousand yuan, while the cost of one battery is about 5-6 ten thousand! The battery of the electric automobile, car, is generally composed of 90 single batteries connected in parallel and in series, the price of the single battery is about 6 to 8 ten thousand yuan, and the sum of the price is about 10 ten thousand yuan plus accessories such as the connection of the outer shell of the battery pack. The battery consumption of electric vehicles is also considered, and generally, the price of a battery pack is at least about three thousand yuan.

4. The research and development and application of new material batteries are difficult. Although the number of new material batteries is now endless, most of them remain in the laboratory, and are a great distance away from the large scale of commercialization. Different types of batteries also have their own advantages and disadvantages in terms of performance. For example, lead acid batteries are low cost, abundant in raw materials and easy to recycle, but have short driving range, poor acceleration power and short life. The nickel-cadmium battery has enough acceleration power and long service life, but has high cost and poor recyclability. The sodium-sulfur battery has high specific energy and can provide long driving range, but the sodium-sulfur battery requires harsh working environment, and the active substance of the sodium-sulfur battery has strong corrosiveness and is easy to explode. The life of a mature battery as a whole is relatively short. Although the domestic automobile manufacturers show that the automobile manufacturers are involved in the research, development and production of new energy automobiles in technical capability, the automobile manufacturers have high technological content and limited models capable of being massively produced, and with the starting of competition of electric automobiles, the research and development cost is too low, the innovation power is insufficient, and the capability of the electric automobile technology with independent intellectual property rights in China is directly influenced.

5. The battery problem is intensively reflected to the experience level of consumers, namely that the charging time is long and the number of the network points is small. The battery charging is an electrolytic reaction, otherwise, side reactions occur during charging, the current quick charging is that 80% of the battery is fully charged in half an hour, the charging time is long, and the charging speed is difficult to improve in a long period of time in the future. Solutions to rapid battery changes are limited by issues of battery quality, ownership, battery model, etc., and may be more helpful for buses, and much less promising for private buses. The process of charging the electric automobile is troublesome, the quick charging generally needs at least two hours, and the battery loss of the automobile is large. Slow charging is generally more than eight hours. There is thus any emergency and there is no way to deal with it at all. The investment of the new energy pure electric vehicle is more expensive than that of a fuel oil vehicle, a power plant is built by using electric power, power transmission and distribution facilities are built, a charging station is also built, a storage battery plant is also built, supporting facilities and supporting services are not perfect, the supporting facilities are few, the construction of the supporting facilities is delayed, the maintenance is inconvenient, and the charging station is difficult to find in China such as the phoenix feather unicorn.

In the embodiment of the method, the first step,

the invention is mainly applied to the industry of pure electric vehicles. The battery of the traditional pure electric vehicle is uniformly fixed integrally, and is charged by a consumer, so that the problems of long charging time, less charging equipment, large potential safety hazard, high charging comprehensive cost and the like are caused. Therefore, each battery manufacturer places a focus on the capacity of a single battery and tries to improve the unit battery density, but the invention places the focus on the convenience of acquisition so that the battery can be replenished at any time and any place, thereby relieving the bottleneck of insufficient battery capacity.

The invention uses a 9-pin extensible pluggable interface triple battery pack as an example, and is shown in the attached figure 3 of the specification:

because the invention adopts the separable pluggable battery, the professional third party can provide the charging service, and the consumer only needs to put forward the power consumption requirement to pay the charging service fee. By combining the fixed network with the mobile network, the consumer self-exchange and the service provider home-exchange are combined, and the self-operated distribution network and the third-party distribution network are combined to establish the charging network covering the whole country, so that a huge third industry is cultivated. The operation mode is shown in the attached figure 4 in the specification:

1. and a third-party charging service provider is jointly established by the power enterprises, the automobile production enterprises and the battery production enterprises. The facilitator mainly provides three services: A. the service provider performs centralized charging, distributes the fully charged batteries according to the order of the battery replacement service retail outlet, and recovers the batteries replaced from the consumers for charging for secondary distribution. B. And the battery safety detection service is provided, and the reliability and the safety of the battery are ensured. C. Provides the centralized recovery processing service of the scrapped batteries and reduces the environmental pollution.

2. Stores, maintenance factories, 4S stores, gas stations and expressway service areas all over the street are used as battery replacement service operation points. The method provides battery distribution requirements for professional charging service centers and provides battery replacement services for consumers.

3. A professional charging service center authorizes the franchisee to directly provide charging service, and performs the same duties as the professional charging center.

The operation process comprises the following steps: when the battery plug board is internally provided with electronic monitoring equipment or a chip to detect that the electric quantity of the battery is insufficient, a prompt is given to a driver through an instrument panel, peripheral battery replacement network points are marked through mobile phone App software, a user refueling network point and time point are collected through a mobile phone App, and network point layout is optimized through big data analysis. The driver can replace the automobile at near or be delivered by a service provider. And (5) replacing the battery which is fully charged after the battery is pulled out from the corresponding position. The battery is replaced by the battery replacement service management system to a professional charging service center for recycling and centralized charging or self-charging by a self-supporting charging service franchisee.

The cost of the battery is born by a professional charging service center, a battery replacement service operation network or a self-operated charging franchisee to be used as an operation asset, and the battery is amortized in times of use or in the service life period, so that the vehicle purchasing cost of consumers can be greatly reduced.

Has the advantages that:

because the invention adopts the extensible pluggable interface battery pack and the plugboard, a third-party professional charging service provider can provide charging service, and compared with the existing integral fixed battery which is charged by a consumer, the invention has the following beneficial effects:

1. the bottleneck problem of battery capacity is overcome. Because the intensive and flexible battery replacement network is established, the consumer can replace the battery at any time and any place without worrying about the problem of battery capacity.

2. The problem of slow charging time is overcome. Due to the adoption of a centralized charging mode of a professional charging service provider, a consumer does not need to consider the charging problem. The battery can be replaced for several minutes, so that the waiting time is greatly reduced.

3. The charging cost is reduced. Because the consumer only needs to pay the electricity fee and the manual service fee, the battery fee is not borne, and the product cost can be greatly reduced. The battery is used as the operation asset by the charging service provider for turnover and centralized charging, the turnover rate of the battery is effectively improved, the cost of the battery can be amortized in stages, the scale effect is realized, and the unit charging cost is reduced.

The safety of the battery is improved. As professional charging service providers provide product safety monitoring, potential safety hazards of the battery can be found at any time in the battery turnover process, measures can be taken to deal with the potential safety hazards, and compared with the situation that consumers have no professional knowledge and conditions, the method can improve the safety guarantee of the battery.

The environmental protection performance of the battery is improved. Because the batteries adopt centralized and unified operation management, the batteries can be intensively scrapped and decomposed, and the environmental pollution pressure is reduced.

The charging flexibility is improved. Due to the adoption of the forms of distribution network points and self-operation joining network points, charging places and charging piles do not need to be additionally built. The investment cost of each dot is low, the effect is quick, the dot establishment is flexible, and the dot density is high. Compared with a gas station, the customer can change the gas station at a fixed point by himself or can change the gas station by sitting on the door, and the gas station is flexible, convenient and rapid. The satisfaction degree of consumers to the electric goods can be greatly improved.

The battery is updated rapidly. Because the operation management and the standardized battery interface are centralized and unified, when new material batteries come into the market, the new and old commodities can realize the quick update of the batteries only by being put in the existing network channel.

And a huge new service industry is developed. The invention needs professional charging service providers and high-density charging network points, so that new energy enterprises which are comparable to the traditional petroleum energy can be developed, and a large number of employment posts of distribution and charging service industry are provided.
