The determination of battery discharge curve, is one of the basic method of the battery performance, according to the discharge curve, it can be judged whether the battery performance stability, and the battery in the allowed maximum current stable work This article comprehensively introduced in detail lithium ion batteries basic knowledge of discharge curve.

1, the charger and maintenanceMention electric vehicle charging is first used in electric car charger Protect the charger is a very important step.

All solid state lithium ion batteries with the replacement of traditional organic liquid electrolyte and solid electrolyte is expected to be fundamentally solved battery security issues, is the ideal chemical power electric cars and large-scale energy storage In order to realize the large capacity and long service life, thus to promote practical of all solid state lithium ion battery, the battery of the development of key materials and performance optimization is urgently needed, including the preparation of high room temperature conductivity and electrochemical stability of solid electrolyte and used throughout the high energy of solid state lithium ion battery electrode materials, the improvement of electrode/solid electrolyte interface compatibility.

For plate after rolling, its production process has been completed The subsequent requires the adoption of reasonable production technology for the cathode to exert its own performance.

Chang 'an BYD in hand joint venture power battery outside the company marked the BYD's power battery for breakthrough This article will talk about battery some main points in the process of splitting and independent.

Lithium ion batteries (Lithium - ion Battery) rely on Lithium movement between the positive and negative ions to complete charge and discharge, is a kind of high-performance batteries Lithium ion battery "The lithium battery"(Lithium Battery), the latter of the anode materials is manganese dioxide or thionyl chloride, the cathode is lithium battery assembly without charge after the completion of the reservoir has electricity, in the process of charging and discharging cycle to cause internal short circuit batteries, lithium crystallization and usually is prohibited from charging, therefore, should not be referred to as the "lithium ion batteries ".

No matter how many disputes for small cylindrical batteries used for EV, 18650 because of high energy density and high cost performance, become more and more important option for the passenger car and car logistics18650 is the advantage of high maturity, high consistency, high energy density, cost, flexible configuration; The disadvantage is that number, pack the difficulty is high, the quality control points.

Today, under the guidance of the electric car development, the progress of the power battery is there for all to see Now on the market are mainly two kinds of batteries, the ternary lithium batteries and lithium iron phosphate batteries and great potential for solid-state batteries are people pay more and more attention to.

Before the launch of the Toyota Hydrogen Fuel Cell Vehicle (MIRAI), IBM introduced its own automotive air lithium battery As early as 2009, IBM proposed the Battery500Project program to develop an air lithium battery technology that allows the battery to maintain a cruising range of at least 805 kilometers on a single charge while maintaining the current car battery volume and cost control.

In September 2017, the Ministry of Industry and Information Technology and other departments officially issued the "Parallel Management Measures for the Average Fuel Consumption of Passenger Vehicle Enterprises and New Energy Vehicles Points" (hereinafter referred to as double-point assessment), which stipulated two sets of points for CAFC (Corporate Average Fuel Consumption) and NEV (New Energy Vehicle) The implementation of the policy has imposed fuel consumption requirements and new energy vehicle production ratio requirements for domestic passenger vehicle enterprises, and adopted punitive measures for enterprises that failed to meet the CAFC and NEV negative points.
