With the continuous increase in market share of new energy vehicles, the integrated mode of photovoltaic, energy storage and charging (photovoltaic+energy storage+charging) is a new type of "source grid load storage" power system formed by the integration and coordinated support of photovoltaic, energy storage, charging piles and other elements through power electronics technology. The proportion of temperature sensor chips in this application is relatively high, and the increment of temperature and humidity products is considerable. Based on the imported data of key customers, we recommend some product models for everyone's reference.
