Shandong Lingong Accessories Direct Train: You should know these things about charging stations!
With the rapid development of new energy, new energy vehicles have now entered every household, and charging stations have become the "gas stations" of our new era. Today, let's take a look at the knowledge you have to know about charging stations!
There is a lot of knowledge about charging stations. Today, I will introduce you to the 240KW/320KW integrated charging station that is popular in Lingong.
classification
Charging piles are mainly divided into integrated machine charging piles and split type charging piles, and most of the 240KW/320KW charging piles we commonly use are integrated. Its main advantages are high integration, relatively low price, and fast charging speed.
Generally, there are many high-power charging station modules with large volumes, and they are mostly split type.
structure
The charging pile mainly consists of a pile body shell and a charging module. Among them, the pile casing includes a control motherboard, display screen, air duct, and module compartment.
Charging module, the main power output unit, with a single module power of usually 30/40KW.
240/320kW all-in-one machine (high-efficiency version)
Advantage 1 Smooth Upgrade
This charging station can be used for 240KW by assembling 6 40KW modules on the pile body, and 320KW by assembling 8 40KW modules.
If the customer purchases a 240KW product in the early stage and needs higher power charging in the later stage, they can upgrade to a 320KW product by purchasing two 40KW modules separately, with extremely low cost.
Advantage 2 Environmental Adaptation
IP54 protection level, the power module adopts more advanced adhesive isolation technology, and the application scenario is often high dust environments. The module protection requirements are high, while ordinary modules have poor protection effect and high failure rate. Using a fully adhesive module greatly improves the dust prevention performance, making it easy to cope with adverse environments. MTBF ≥ 550000 hours.
Advantage 3: Lower power loss
The third-generation 40kW module technology has an energy conversion efficiency of up to 95.5%, with lower power loss and higher efficiency, leading the industry.
Advantage 4: Wide voltage output
The ultra wide output voltage range of 200-1000V leads the future trend of wide voltage batteries. Its parameters are as follows:
Purchasing knowledge
According to the requirements of national standards GB/T20234 and GB/T27930, the maximum charging current of the battery is 400A. For vehicles with a carrying capacity of 282kWh, the upper limit of the dual gun charging power demand is around 270kW, and 240kW dual gun charging is the best cost-effective choice. If
Reason 1: Compared to 320KW power, 240KW can maximize the efficiency of the charging station itself, while a 320KW charging station can achieve a maximum efficiency of 270KW;
If we choose a 360KW charging station to charge our equipment, its charging effect will be limited by the device end, and its charging effect will be completely consistent with that of 320KW, resulting in "performance surplus".
Reason 2: As shown in the figure below, during the fast charging stage, the 240KW charging station is only 5 minutes less than the 320KW charging station, and the impact is not significant.
