In the battery pack of the power battery, the difference between the monomers always exists. Taking the capacity as an example, the difference will not tend to disappear, but gradually deteriorate. The same current flows in the battery pack. Relatively speaking, the one with large capacity is always at low current, shallow charge and shallow […]
Power batteries for electric cars are one of the key factors affecting the development of electric cars. At present, the power batteries of new energy cars mostly use lithium-ion batteries, which are small in size, light in weight and high in working voltage (about nickel-hydrogen batteries, nickel-cadmium batteries). 3 times), long life, many cycles, no […]
New energy car power batteries can be divided into two categories: storage batteries and fuel cells. Storage batteries are used in pure electric cars (EV), hybrid electric cars (HEV) and plug-in hybrid electric cars ( PHEV); fuel cells are dedicated to fuel cell cars (FaV). ①storage batteryStorage batteries suitable for pure electric cars can be […]
①The standard of electric car charging system At present, the construction of electric car charging stations is small in scale and small in number, and most of the related technologies of electric car charging stations are still in the initial stage of practical application. The international standard for electric car charging systems is mainly IEC61851:2001 issued by IEC. The […]
Although the construction of electric car charging stations is affected by different factors, their construction methods and construction requirements need to be determined according to actual conditions. However, with the gradual promotion and industrialization of electric cars and the increasing development of electric car technology, the technical requirements of electric cars for charging stations have shown a consistent trend, […]
1) Technical conditions of electric car charging piles (1) When the charging pile is not connected to the power battery, the charging pile is automatically initialized to the conventional control charging mode after self-inspection (manual, IC card or charging pile monitoring system operation mode can be selected). When the charging pile is manually operated, it […]
The business model of an electric car charging station (pile) refers to a mode in which electric car users select a charging station (pile) at a fixed location to directly charge the car’s battery when the car’s electric energy is about to be exhausted. This is the first business model considered for electric car charging stations. Under this […]
In the previous article, we talked about the Electric car charging billing system and charging station application scheme. In this article, we will talk about the classification of charging stations (piles). (1) According to the installation method, charging piles can be divided into floor-standing charging piles and wall-mounted charging piles. ①Floor charging piles are suitable […]
⑴ Electric car charging and billing systemThe charging and billing system for electric cars consists of the following three parts:① The charging and billing system management platform provides centralized management of the basic data involved in the system, such as electric car information, power purchase user information, and asset information.②The charging and billing system operation […]
Electric vehicle charging (swapping) power stations undertake the important mission of providing electric energy to electric vehicle power batteries. High-quality and multi-functional charging equipment can effectively protect the power batteries, monitor the working status of the power batteries, and provide the most efficient charging scheme for the power battery packs. . If the power battery […]
