Standardized power battery for vehicle

Abstract

The invention discloses a standardized power battery for a vehicle. An existing electric automobile power battery is non-standard and has many problems. In the invention, a battery box is provided with an electrode interface and a communication interface, battery identity related information is stored in a battery identity recognition module in the battery box, a charging information recording module records charging historical information of the battery, a working state recording module records the working state and parameters of the battery in the whole process, an automobile central controlunit or a user reads information received by a communication module through the communication interface, a date and clock unit provides real-time date and time data for the charging information recording module and the working state recording module, and an information acquisition unit acquires battery temperature, output voltage and charging and discharging current data and provides the data tothe charging information recording module and the working state recording module. The maintenance cost of the battery is reduced, the safety of charging equipment and the battery is ensured, the service life and the utilization rate of the battery are improved, and meanwhile, the battery can be quickly replaced.

Description

technical field [0001] The invention relates to a battery, in particular to a standardized vehicle power battery. Background technique [0002] As a green and environmentally friendly new energy vehicle, electric vehicles have the characteristics of low noise, no direct pollution emissions, large torque and fast start-up. They are one of the strategic emerging industries supported by my country. At present, electric vehicles can be roughly divided into two modes: rechargeable and battery replacement. Except for some bus companies and large car rental companies, most private cars use the charging mode. The main reason for this situation is that there is currently no unified national standard for vehicle power batteries. Unlike commonly used dry batteries, as long as the models are the same, batteries produced by different manufacturers can be directly interchanged. However, in electric vehicles, the sizes and specifications of the battery compartments in vehicles produced ...

AI Technical Summary

Problems solved by technology

[0003] But charging-mode EVs have three glaring weaknesses

First, the cost of purchasing batteries is too high, generally accounting for about 50% of the total price of electric vehicles. Therefore, although the electricity bill is not high, the actual operating cost of electric vehicles is not low considering the battery factor

Second, the charging time is too long. Slow charging generally takes several hours, and fast charging also takes more than tens of minutes.

It is unacceptable for users who are accustomed to using fuel vehicles, and fast charging has a great impact on the service life of the battery

Third, the battery mileage calculation is not accurate enough. Low temperature, high-speed driving, braking, heating and cooling air conditioners, etc. have a great impact on the battery mileage, causing drivers to worry about mileage.

However, the aforementioned weaknesses of charging-mode EVs are unlikely to be resolved any time soon in the foreseeable future
