Description

Battery replacement method for electric automobile

Technical Field

The invention belongs to the technical field of electric automobiles, and particularly relates to a battery replacement method for an electric automobile.

Background

The electric automobile uses electric power as energy and is a green vehicle. Specifically, the electric vehicle is equipped with a battery, which provides a power source for the electric vehicle. Since the electric energy stored in the battery of the electric vehicle is constant, the distance that the electric vehicle can travel without being charged is limited. In order to make the electric vehicle travel longer, there are some charging stations installed on the road side to provide charging for the electric vehicle. The charging station is similar to a gas station of a common automobile, and when the battery of the electric automobile is consumed or is about to be consumed, the electric automobile can charge the battery in the charging station; when the battery is fully charged, the electric vehicle can continue to run. When the electric vehicle charges the battery in the charging station, the electric vehicle needs to stop for a long time for waiting, and the waiting time is two hours less and seven-eight hours more.

Therefore, the applicant supplements energy for the electric vehicle in a battery replacement mode, and generally adopts two modes to replace the electric vehicle in the process of completing the replacement of the electric vehicle, wherein 1, a fully charged battery of an energy station is transported to the electric vehicle needing to be replaced, the replacement operation is carried out, and then a replaced undercharged battery is transported to the energy station for charging; and 2, driving the electric vehicle needing replacing the battery to an energy station, directly performing battery replacing operation, and charging the replaced underrun battery.

Among the two battery replacement methods, the 1 st battery replacement method is most commonly used, in which a power transmission vehicle for transporting a battery is used in the steps of transporting a fully charged battery to an electric vehicle requiring battery replacement, performing battery replacement operation, and transporting a replaced undercharged battery to an energy station for charging. However, in the prior art, no matter the full-charge battery or the undercharge battery is directly stacked in the vehicle, the position for placing the battery is not fixed, and the full-charge battery and the undercharge battery are easy to mix together. When the power transmission car conveys a fully charged battery to the vicinity of the electric car to be charged, the undercharged battery on the electric car to be charged is usually detached manually, and in order to enable the power transmission battery to transport more batteries, namely, no spare battery containing station exists on the power transmission car, the undercharged battery can only be placed on a temporary battery containing station; and then transferring the full-charge battery on the power transmission vehicle to the electric vehicle to be replaced, and installing. After that, the battery placing station is vacated on the electric power transmission vehicle, and the undercharged battery placed in the temporary battery placing station in advance is transferred to the electric power transmission vehicle.

When the power transmission vehicle is used, the undercharged battery and the fully charged battery need to be transported by manpower, a temporary battery placing station is needed, the steps of taking up and putting down the undercharged battery by operators can be increased, and the full charged battery and the undercharged battery need to be transported together. Therefore, the existing power transmission vehicle has the defects of inconvenient use, low power transmission efficiency and high labor intensity of workers when in use.

Therefore, it is a technical problem to be solved by those skilled in the art how to provide a method for replacing batteries of an electric vehicle, which can better transfer batteries, improve battery replacement efficiency, and reduce labor intensity of battery replacement.

Disclosure of Invention

Aiming at the defects of the prior art, the technical problems to be solved by the invention are as follows: the battery replacing method for the electric automobile can better transfer the battery, improve battery replacing efficiency and reduce labor intensity of battery replacing.

In order to solve the technical problems, the invention adopts the following technical scheme:

the method for replacing the battery of the electric automobile is characterized by comprising the following steps that a, two independently arranged transfer trolleys are adopted, battery containing stations are arranged on the transfer trolleys, b, after one of the transfer trolleys runs to be connected with the electric automobile to be replaced, the under-current battery on the electric automobile to be replaced is detached and placed on the battery containing station of the transfer trolley, and then the transfer trolley containing the under-current battery runs to a specified position; c, placing full-charge batteries on a battery containing station of the other transfer trolley, driving the transfer trolley to be connected with the electric vehicle to be replaced, taking down the full-charge batteries on the transfer trolley and installing the full-charge batteries on the electric vehicle to be replaced, and driving the transfer trolley to a specified position; and finishing the battery replacement operation.

In the technical scheme, the operation steps are adopted, the underbattery detached from the electric vehicle to be charged is directly placed on the transfer trolley, so that the underbattery can be directly transferred to a specified position by the transfer trolley without finding an extra empty space, and the steps of lifting the underbattery from the extra empty space and doing work to waste physical power can be reduced. And the under-charged battery and the fully charged battery are transferred to the electric vehicle to be replaced through the transfer trolley, so that the labor intensity of the whole battery replacement can be reduced, and the battery replacement efficiency is improved.

In the specific embodiment, the step a comprises the steps of placing a battery tray containing fully charged batteries on one transfer trolley, and placing a vacant battery tray on the other transfer trolley; the battery tray is provided with the battery containing station.

Thus, the undercharged battery and the fully charged battery are respectively placed in different battery trays, so that the probability of mixing the undercharged battery and the fully charged battery can be reduced. And, can conveniently carry out follow-up charging operation to the battery that is owed.

As optimization, the step a comprises the steps of placing two transfer trolleys, a battery tray containing full-charge batteries and an empty battery tray on a piece of transportation equipment, and driving the transportation equipment to the position of the electric vehicle to be charged; and taking the two transfer trolleys down from the transportation equipment, and respectively placing the battery trays containing the fully charged batteries and the empty battery trays on the two transfer trolleys.
