Regardless of the advantages of “evidence†such as energy saving and environmental protection of electric vehicles, electric vehicles are more convenient to charge than traditional fossil fuels: no fire and explosion protection management storage, no special site selection away from crowded places, no need to occupy Larger space, no need for special pipelines or automobile transportation, no special tubing, trachea or oil and gas meter, etc., it is easier to achieve self-service DIY operation. This all stems from the use of the "electricity", an easy-to-transmit, long-distance energy form with an off-the-shelf use of the network: just a charging post with a power outlet.
However, things are not always that simple. When von Roll, a company with 200 years experience in liquid and gas infrastructure construction, designed its truly commercial charging pile Electrant, it still considered many details:
1) Small and beautiful appearance: easy to collaborate with different surroundings that may be close to dense crowds;
2) Usage rights: Who can use it? Who should pay? Needs identification and communication capabilities;
3) Anti-riot function: It cannot be vandalized or illegally used by people;
4) Measure electricity consumption to generate bills;
5) Safe and reliable: adapt to wide temperature, humidity, altitude, and tolerance to shock and vibration; it is not economical to separately install air conditioning for charging piles (such as used in outdoor cell phone base stations); unstable and high failure rate charging piles Only the electric vehicle drivers eager to hurry will start running into trouble. They lament that "still gas stations are good" and so on.
The final design solves the above problem:
1. Beautiful and compact shape designed by the designer of the mouse and coffee machine;
2. Anti-riot electronic lock, only wireless identification card or smart phone can open wirelessly;
3. Electronic pricing and billing, and sending bills via SMS via mobile phone network;
4. Powered by PULS Poole power supply ML60.242.

solution:
1. Most of the charging stations for electric vehicles are built on the side of outdoor roads. The characteristics of high and low temperature, dusty and humid environments are required to be considered. The products are required to be capable of wide temperature operation and strong environmental adaptability. Most PULS Poole power supplies are designed for continuous, robust operation in the -25°C to 70°C temperature range. ML60.122 and ML60.242 can even meet the stable output in the temperature range of -40°C to +70°C. Whether it is in the snow-covered north or in the scorching desert, the product can work steadily and can also work at an elevation of 6000m. Height, which greatly enhances the reliability and application of the charging pile. In addition, PULS Poole Power is fully compliant with 5-95% relative humidity: IEC 60068-2-30 certification standards.
2, good seismic performance and heat dissipation. PULS Poole Power Concept and Power Series are all IP20-rated metal housings that are robust and durable. Compared with other brands, they have the smallest size and can be installed side by side with the same power. This prevents the heat emitted from the lower power supply from being applied to the upper power supply when the power supply is installed up and down, which greatly improves the stability of the electrical system. PULS Poole Power has a conversion efficiency of up to 95.3%, completely relying on natural cooling, while saving energy consumption, to avoid excessive heat generated by the power supply itself, thereby affecting the surrounding components. In addition, PULS Poole power supply has a very light weight, according to the principle of mechanical vibration, the vibration of a light-weight object is relatively small. PULS Poole Power continues its strong work in high-vibration mining equipment.
3. The number of electric vehicle charging station outlets is generally more and more dispersed and the maintenance cost is higher, so the products are required to have high average failure-free running time. PULS Poole power products have an average MTBF of more than 1 million hours and an expected service life of at least 8 years or more, which greatly reduces the maintenance costs of the electrical system in the charging pile. This also allows PULS Poole power to be used in other applications. Brand exclusive power honored when competing.
4, AC input isolated AC-DC charger output voltage is 50% to 100% of the rated voltage, and the output current is rated current, the power factor should be greater than 0.85, the efficiency should be greater than or equal to 90%. The efficiency of DC input non-isolated DC-DC chargers is to be determined. The power factor of PULS Poole Power Quality Q Series is maintained at 0.9 or above, which is unique in the industry.
Simple, robust, robust, and efficient, this is the most direct experience for PULS Poole power supply to customers in many industries. Therefore, PULS Poole Power is a true DIN rail-type power supply standard maker. With the continuous development of electric vehicle charging stations, when most of the power supplies on the market can not meet the stability and high reliability required by the application, PULS Poole Power once again acts as a “one after the other.†Just as a global power equipment supplier commented on PULS Poole Power: PULS Poole Power, a strong control system.
