Description

Shared battery intelligent electric vehicle and use method

Technical Field

The invention belongs to the field of takeaway and express business operation, and particularly relates to a shared lithium battery intelligent battery replacing vehicle for two-wheeled and three-wheeled electric vehicles and a use method thereof.

Background

With the rapid development of O2O, take-out and express business has developed very rapidly in recent years, and daily orders break through tens of millions in take-out and express peak periods. The main vehicles of the take-out small brother and the express small brother are two-wheel and three-wheel electric vehicles.

Two-wheeled and three-wheeled electric vehicles currently employed in the industry have two features: firstly, lead-acid batteries are used as a power source of the electric vehicle, and secondly, a self-charging mode is adopted. These two features have severely limited the rapid development of the industry.

Firstly, lead-acid batteries have poor endurance, long charging time, quick battery loss, large volume, heavy weight, low efficiency and the like, and can not meet the development needs of take-out and express industries. Secondly take out and sell little brother and express delivery little brother self mode of charging seriously influence the efficiency of express delivery:

1) Take-out little and express little own to prepare the multiunit battery, especially up to 4 groups in winter, very inconvenient:

2) When the battery is not charged during transportation, the transportation is stopped, and no matter how far the road is, the battery is replaced by a fully charged battery:

3) The method can find the charging place by oneself, and has long charging cost and less calculation.

The electric vehicle is changed into a battery to be charged by a driver, so that the pain is solved thoroughly and effectively. The power conversion is originally in the electric automobile field, and is accepted by the market gradually, but no taster exists in the two-wheel and three-wheel electric automobile industries. Today, in the double tuyeres sharing the economic and takeaway and express markets, we consider that the opportunity for two-and three-wheeled electric vehicles to change batteries is reached.

According to market research, new energy lithium batteries can be used for long-term operation of take-out little and express little, so that operation efficiency can be improved, operation cost can be saved for the take-out little and express little, and power can be contributed for reducing haze. The thousands of calling lithium battery power exchange stations-shared lithium battery power exchange stations and shared lithium battery power exchange stations are about to become the operation centers of the out-of-service small-cell, express small-cell and the whole timely delivery industry.

Firstly, solve the problem of continuation of journey in winter, in cold winter in north, take out and express delivery order volume in recent years is proliferated, and each district needs to add 50% talents and can accomplish order volume, shares the battery mode of trading, especially add shared lithium cell and trade the car, has realized infinitely continuation of journey. Not only reduces the cost of the people, but also reduces the requirements of the people for increasing the people and improves the efficiency of the people.

Secondly, the problem of distribution efficiency of the rider is solved. After the shared battery replacing mode is used, the cost of self-contained multiple batteries and self-contained charging points is saved, the batteries are replaced nearby and in an emergency mode, the time is saved, the daily receipt is increased, and accordingly income is increased.

And thirdly, big data management is carried out, so that the battery management difficulty is solved. The battery is made better, the BMS is made better, the battery cannot be monitored and managed, the better product is also required to be charged by the electric vehicle by depending on a good technology and business mode, the later battery data management cannot be achieved, and the whole battery system can be managed through sharing the power conversion mode, so that the utilization rate of the battery is greatly improved.

Based on the advantages and the situation of the current vigorous development of the O2O of takeaway and express, the two-wheel and three-wheel electric vehicles can be actively responded by the market after being pushed out in a battery replacement mode.
