Description

Battery system and method for electric motorcycle

The present invention relates to a battery exchange system and method of an electric motorcycle, in particular, by collecting information from one battery exchanger and a plurality of electric motorcycles using the same and preparing the pre-charged battery through the battery exchanger using the collected information , When the battery of the electric motorcycle is discharged, the present invention relates to a battery replacement system and method for an electric motorcycle configured to be used without interruption by replacing the battery with a pre-charged battery in a short time.

Delivery industries that deliver food, etc. using two-wheeled vehicles, such as motorcycles, usually operate multiple two-wheeled vehicles simultaneously. Delivery two-wheeled vehicles repeat dozens of delivery and store returns a day.

[Table 1] below shows the status of the operation of two-wheeled vehicles in the delivery industry. Referring to this, as a result of analyzing the operation status of two-wheeled vehicles in the delivery industry operating three wheeled vehicles in the city of Seoul, an average of about two hours driving a car about 80 km per hour for an average of nine hours per day and about 3.3 delivery tasks per hour To perform. During this process, it was confirmed that it took 18.4 minutes for a two-wheeled vehicle to leave the store on average, deliver it to the delivery site, and return to the store while handling an average of 29 deliveries per day.

	Total mileage (Km)	Total operating time (h)	The number of delivery (times)	Hourly driving distance (km)	Number of deliveries per hour (times)	Average processing time per delivery (minutes)
No. 1 vehicle	72.2	9	28	8.0	3.1	19.3
Vehicle 2	78.4	9	29	8.7	3.2	18.6
No. 3 vehicle	82.8	9	31	9.2	3.4	17.4
Average	77.8	9	29.3	8.6	3.3	18.4

In general, in the case of an engine two-wheeled vehicle using gasoline fuel, the gasoline fuel can be fully filled to operate around 100 km when refueling, so that the two-wheeled vehicle can be operated with fuel refueling once a day in the use of the delivery two-wheeled vehicle.

On the other hand, in the case of an electric two-wheeled vehicle currently on the market, it is possible to drive about 40 km or more when driving on a real road after one charge. In addition, about four hours of charging time is required for additional driving, and the electric two-wheeled vehicle can be parked for 4 hours. I need a place where I can.

For this reason, it is known that electric two-wheeled vehicles are difficult to use for commercial purposes that require an average of about 80 km or more per day.

In addition, in city centers with many apartments, such as apartments, villas, and multi-family houses, there are limitations in using electric motorcycles for general purposes, not for commercial purposes, such as delivery, because there are many restrictions on securing facilities that can stand and charge electric motorcycles for a long time. do.

As mentioned above, the driving distance after charging once for an electric motorcycle under a traffic flow in the city where traffic stops due to traffic signals and traffic stops frequently occurs is usually around 40 km. Battery charging is required for additional driving, but it takes about 4 hours to fully charge due to the limitations of the current battery and charging technology, and it takes more than 30 minutes to charge rapidly.

On the other hand, in the case of a two-wheeled vehicle operated for delivery and consignment purposes, it is necessary to travel about 80 km or more for an average of eight hours or more per day, and it is impossible to stop the operation of the two-wheeled vehicle for a long time due to the nature of the delivery service.

Therefore, due to the characteristics of the operation of a two-wheeled vehicle for the purpose of delivery and consignment, the existing charging-type electric two-wheeled vehicle that can travel only about 40 km after a single charge and requires long-term battery charging for additional driving cannot be used for delivery and consignment purposes. It is said to have been done.

In order to solve this, in order to use the electric motorcycle continuously in the delivery industry, an alternative method may be an alternative method of charging a spare battery and replacing it with a prepared rechargeable battery when discharging the battery.

In particular, as shown in Figure 1a, in the case of a delivery industry that operates a large number of two-wheeled vehicles (usually three), if there is an extra battery as many as the number of electric two-wheeled vehicles, there will be no business interruption due to battery discharge.

However, since the battery price accounts for more than 40% of the total price of the electric two-wheeled vehicle, the delivery industry that requires the operation of a large number of two-wheeled vehicles to prepare an extra battery for the number of electric two-wheeled vehicles is expensive.

As a solution to this, as shown in FIG. 1B, a method of sharing a battery between two electric motorcycles by loading a battery of a spare quantity smaller than the number of electric motorcycles into a battery exchanger with a charging function is an alternative. It could be.

In this case, however, if the time to replace the battery arrives at the same time for two or more electric two-wheeled vehicles, one of the two may not be able to replace the battery immediately and may not be able to operate the two-wheeled vehicle until the replaced battery is charged.

Meanwhile, lithium-ion batteries are used in recent electric vehicles. In order to increase the charging speed of the lithium ion battery, the amount of charge applied to the battery through the charger is increased. However, in this case, an abnormal amount of charge is introduced into the battery, causing damage to the electrode plate of the battery, and as the amount of damage increases, the total amount of charge that can be stored in the battery decreases. Eventually, if repeated damage is applied, the life of the battery will inevitably decrease.

The technical problem to be solved by the present invention is to use an electric two-wheeled vehicle to obtain energy and not to charge the electric two-wheeled vehicle for a long time, but to identify the battery replacement time of the electric two-wheeled vehicle in advance and to charge the battery in advance through a battery exchanger. It is to provide a battery replacement system and method for an electric motorcycle configured to be used without interruption of operation of the electric motorcycle by preparing a battery and replacing the battery with a pre-charged battery through a battery exchanger in a short time when the battery of the electric motorcycle is discharged.
