Description

Electric vehicle battery pack self-replacement/warning system

A battery pack self-replacement/warning system, particularly a battery pack self-replacement/warning system for electric vehicles.

In recent years, in view of rising environmental awareness and serious global warming, electric vehicles have attracted attention as a new type of transportation without exhaust emissions. Therefore, governments around the world have drawn up plans to end fossil fuel vehicles, and large automobile and motorcycle manufacturers have Investing in human capital to compete for research and development of electric vehicle technology. Among them, in addition to the power mechanism led by electric motors, the battery system that is the source of power attracts the most attention. The capacity and output current of lead-acid batteries for ignition in traditional cars or locomotives are very limited. The demand for high capacity and high output power of electric vehicles cannot be met.

However, vehicle battery packs are also advancing rapidly due to the above requirements. First, the traditional lead-acid battery was replaced by the 18650 standard lithium-ion battery, and then the lithium iron phosphate battery became the originator of the power-grade lithium battery, and now the latest 21700 size Nickel-cobalt-manganese ternary lithium batteries with specifications have become the mainstream of power-grade lithium batteries (specified for Tesla electric vehicles). These ever-improving battery packs bring longer driving distances and higher cruising speeds to electric vehicles. However, no matter what kind of battery is used to make electric vehicle battery packs, the battery will eventually run out as electric vehicles are used. When charging is required, the above-mentioned batteries have a certain internal resistance, so it takes a long time to charge the above-mentioned battery pack. Even if new charging technologies such as Tesla’s Supercharger are constantly being introduced, they must Required for traditional vehicles to refuel at gas stations To complete the charging of electric vehicles within a period of time, the current charging facilities for electric vehicles on the market are still unable to achieve.

To this end, many electric vehicle suppliers on the market currently build a battery exchange system that includes many battery charging/exchange sites to meet the users’ immediate demand for electricity. The above sites have a certain number of battery charging points, and some The charging station is also equipped with a charged battery to be exchanged for the user to exchange the battery whose power is too low, and then the depleted battery is charged until the charge is completed for the next user to exchange. However, these battery exchange systems usually have to set up battery exchange sites in densely populated places for the convenience of users, and passively accept users for battery exchange after the users arrive at the site. Therefore, it happens from time to time that the user's electric vehicle is exhausted halfway, and the user cannot reach the nearest station and must go to the nearest station.

Please refer to Figure 7 and Figure 8. Although some more advanced companies provide users with exclusive APP for this, users can check the location of each battery charging/exchange site 8 in advance, but on the one hand, it may not reveal the current exchange When the user arrives at the nearest battery charging/exchange site 8 due to the number of batteries, it may happen that the exchangeable battery pack has been completely exchanged by other users. You must wait for the charging battery pack 81 to complete before performing the exchange or accept the charging Batteries; or the battery pack is too low or malfunctioning when the user is driving an electric vehicle, but the electric vehicle can only be left on the roadside because of the need to rush to other trips, and the battery pack will be returned to the original place after the trip is over There are shortcomings such as waste of time and lack of convenience in exchange matters. Due to the above-mentioned reasons, it is still impossible to completely solve the user's battery exchange problem, and such poor user experience causes doubts from potential users and hinders the further development of the electric vehicle market.

In addition, because the location of the battery charging/exchange site 8 usually needs to apply to the power company for high-current power consumption, sometimes it will exceed the regional grid load and be rejected by the power company or must It is necessary to limit the number of exchange batteries, and residents around the battery charging/exchange site 8 have begun to question the electromagnetic radiation pollution of the site, and even the safety concerns caused by fire accidents caused by defective battery packs during high current charging. The problems make it increasingly difficult to obtain land for the battery charging/exchange site 8, especially in densely populated locations, which greatly increases the cost of setting up the battery charging/exchange site 8 and the exchange system.

In addition, battery packs for electric vehicles are in high demand and are usually not manufactured in large quantities by manufacturers with different specifications, so the unit price is high, and because they are movable components, they are also prone to theft. Therefore, how to effectively protect the battery pack has become an electric Important issues for automakers

Therefore, how to provide battery replacement services in real time when electric vehicle users need electricity, and to avoid the difficulty and cost burden caused by setting up battery charging/exchange sites have become the industry’s active goal, which is the problem to be solved by the new model. .

In order to solve the above problems, one purpose of the present invention is to provide a self-replacement/warning system for electric vehicle battery packs, which can be used to order batteries via the Internet when the battery packs of the electric vehicles are too low or fail, and deliver the battery packs to them. The aforementioned electric vehicles are exchanged instantly.

Another object of the present invention is to provide an electric vehicle battery pack self-replacement/warning system for issuing an alarm when the battery pack of the electric vehicle is too low or malfunctions, so that the system and/or the user of the electric vehicle can start immediately Battery pack exchange.
