According to Market Research Future, the global electric vehicle market was valued at USD 208.95 billion in 2021. Its size is projected to be worth USD 957.42 billion by 2030, registering a CAGR of 24.51% during the forecast period 2022 - 2030. And given the growing demand for low emission commuting, governments also significantly support installing electric vehicle charging stations through subsidies and tax rebates, so as to speed up the growth of their country's EV charging networks.

As an experienced manufacturer of one-stop power supply solutions, MORNSUN has a line of products engineered for charging station applications and to address the challenge of the latest in electric vehicle charging technology.

It is mainly divided into AC charging stations and DC charging stations. AC charging stations are divided into AC Level 1 EVSE and AC Level 2 EVSE, which deliver AC power to the on-board charger of the vehicle. AC charging stations are generally small current charging piles, flexibly installed, and it takes an average of 2-8 hours for a full charge depending on the vehicle. They are very suited for small passenger electric vehicles, mostly used for residential applications, as well as fleet, multifamily, shopping malls, offices and other commercial space. DC charging pile is a high-powered Level 3 charger. It delivers DC power to the battery. DC charging station draws large current, with a large pile body armed with large charging capacity, and is usually able to charge the battery to 80% of the charging state within 30 minutes. DC charging stations are suitable for fast DC charging of private electric vehicles, electric buses, hybrid buses, taxis, engineering vehicles, etc., and are mostly used in the public and workplaces.

Cost-efficient, compact and reliable AC/DC power supplies are critical for both the Control system of AC Charging Station and DC charging station. When designing the power supply for EV charging stations, you are faced with multiple challenges and requirements:

● High ability to resist voltage fluctuations and surges
● High ability to resist operating temperature changes
● Outdoor weather and environment conditions
● Other specific requirements based on the type of selected charging station power supply

Offering a wide working temperature range and better EMI performance.
When charging stations run outdoor, as there is a huge temperature change among different seasons within a year, so power supplies used inside should meet a demanding temperature requirement of -30 degrees Celsius to 70 degrees Celsius. In particular, a complicated environment may also result in strong electromagnetic interference or humid condition, thus the power supply design needs to meet Surge line to line ±1kV, EFT ±2kV, or conformal coating requirements.

Enabling a wide input voltage range.
In order to meet the voltages requirements of distribution power grids in different countries and avoid voltage fluctuations and surges, the power supply design requires 85 VAC to 305 VAC wide input voltage range. The charging stations can maintain normal operation even when high input voltage transients are present.

MORNSUN’s line of power products includes AC-DC converter, DC-DC converter, transceiver module, and SiC/GaN driver power supply. All our power supply solutions are well-adapted to meet the demands mentioned above. For example, both of our 1-15W open frame AC-DC converter LS series and 3-30W encapsulated AC-DC converter LD-R2 series offers compact size, a wide input voltage range of 85~305VAC that help meet the key requirements of power design for the EV control system. High efficiency up to 90% coupled with the extended -40℃ to +85 ℃ operating temperature range delivers more power and high reliability in harsh conditions. They also deliver good EMC performance with conducted emission and radiated emission meeting CISPR32/EN55032 CLASS B, which makes them highly reliable in some extreme conditions when charging.
