As we all know, charging pile as the most important part of the new energy automotive industry, has been highly concerned. However, due to site constraints and immature commercial models and other factors, leading to the development of China's charging pile industry is very slow. Data show that from January to September this year, China's total production of new energy vehicles 144,200, an increase of 2 times. As of the end of September, the number of new energy vehicles in the country was about 280,000. However, only 35,000 charging piles, pile ratio of 8: 1. There is a voice in the industry that in the short term, the cake in the market of billions of charging piles is just the temptation to hang in the air.

Cores are mainly ferrite-based, because the power used in new energy vehicles inside the module power is generally not large, basically by a few 15kw power put together into the charging pile required power, and Module power supplies with ferrite materials offer the highest performance, PFC inductors for charging piles, and metal powder cores now available, and the performance of this solution can be very high.

PV for charging pile power?

Solar photovoltaic power generation is a hot issue of great concern to the modern society, and electric vehicles themselves have also been incorporated into the development plan of our country. Combining these two major contexts, it is important to integrate the distributed photovoltaic and EV charging facilities together to achieve synergies through optimal configuration and operation.

Current domestic photovoltaic is still in the solar energy into electricity, the electric energy into the network stage. In theory, when the photovoltaic conversion of the current out with the same electricity, charging the charging pile is no problem. But now the PV inverter efficiency is not high enough to convert light into the same current as the mains. "Now PV panels are out of DC, the voltage is very small, need to be boosted by the inverter into our grid, the light can be boosted to the same current with the electricity, the photovoltaic inverter is bound to be inefficient Put forward higher requirements, and the inverter needs magnetic core,so our magnetic material industry challenge is quite big.
