Charge-exchange electric vehicle charging system and charging method thereof

Abstract

The invention discloses a charging system and a charging method of a charging-replacing electric vehicle. The system comprises a battery consumption measuring module of an electric vehicle, a chargingand replacing control module of the electric vehicle, a BMS of the electric vehicle, a VCU of the electric vehicle, a locking device of a power battery pack of the electric vehicle, a charging and replacing station server, a charging pile, a replacing device, a data terminal server and a mobile phone customer service terminal. At work, the charging and exchanging station server sends out power consumption inquiry information to the charging and exchanging control module of the electric vehicle, the charging / replacing control module inquires the output electric quantity information of the power battery stored in the battery electric quantity measuring module, and transmitting the power quantity information to the charging and replacing station server, the charging and replacing substationserver calculates the cost according to the power quantity and transmits the cost information to the data terminal server, the data terminal server sends the payment information to the mobile phone customer service end, the vehicle owner pays the cost through the mobile phone customer service end, and after the payment is completed, the vehicle owner selects charging or power exchange service.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a charging system and a charging method for a battery-rechargeable electric vehicle. Background technique [0002] At present, the starting time of domestic electric vehicles is not very long, and the battery-rechargeable electric vehicle is a new business model. The charging and replacing business in the charging and replacing station requires an effective billing system and method. [0003] Fuel vehicle billing is based on the amount of fuel refilled each time to calculate the fuel cost, that is, the customer adopts the method of buying first and then using it. The existing rechargeable electric vehicle also calculates the cost based on the amount of charging. These two payment methods are both It belongs to "pay before use". If this kind of payment method is used to bill the rechargeable electric vehicle, there will be many problems. First of all, when t...

[0006] At the same time, due to factors such as the service life of each battery and the storage time after charging, the actual storage power of the battery will be reduced to varying degrees compared with the charging power. If only the charging power of the battery is billed, the customer will pay more.

[0007] At present, when the rechargeable electric vehicle is charging, the owner's information and vehicle information are stored in a charging IC card, and the information of the vehicle can be verified only through the IC before charging, but the power battery pack of the rechargeable electric vehicle It can be replaced at any time, but the IC card information cannot be updated and matched with the information of the real vehicle in real time, and the service station cannot obtain the real information of the actual vehicle, resulting in wrong or failed battery replacement

Therefore, rechargeable electric vehicles cannot use IC cards to store and verify vehicle information, and IC cards are inconvenient to carry and easy to lose.
