1. Charging requirements for power battery packIf the charging mode of the power battery pack adopts the two-stage charging mode of “current limiting and voltage limiting”, at the beginning of charging, generally the best charging rate (0.3CA for lithium-ion batteries) is used for current-limiting charging. At this stage, due to the low electromotive force of […]

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 […]

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 […]
