Onsemi launches DC high-speed electric vehicle charger solution

ON Semi (Nasdaq: ON), a leader in intelligent power and sensing technologies, announced the launch of nine new Elite Silicon Carbide (EliteSiC) power integration modules (PIMs). It supports ultra-fast DC chargers for electric vehicles and bi-directional charging functions for energy storage systems (ESS). SiC-based solutions dramatically improve system costs through higher efficiency and simpler cooling mechanisms, reducing size by up to 40% and weight by up to 52% compared to existing silicon-based IGBT solutions. With these platforms, designers have all the key components they need to quickly deploy a reliable, efficient, and scalable network of ultra-fast DC chargers capable of charging electric vehicle batteries up to 80% in just 15 minutes.

According to J.D. Power’s 2023 Electric Vehicle Considerations Survey, nearly half of U.S. consumers cite accessibility to charging facilities and fast charging speeds as reasons for not purchasing an electric vehicle. This concerns whether it is possible to enjoy an easy and smooth driving experience like existing internal combustion engine (ICE) vehicles. In the United States, the availability of electric vehicle chargers must more than quadruple by 2025 and eight-fold by 2030 to keep up with demand and provide equal access to public charging stations for drivers.

As a result, this rapid increase in electricity demand could place enormous strain on the current power grid, causing overload. To alleviate this problem, two-way charging is called vehicle-to-grid (V2G), which enables both regular battery charging and the ability to use the electric vehicle as an energy storage system to power the home when needed. has emerged as a key solution for implementing.

The solution enables ultra-fast DC charging networks and V2G power transmission systems, solving accessibility and speed issues by enabling frequent charging of vehicles more quickly than other methods that require hours or days.

ONSemi offers the most comprehensive PIM portfolio capable of configuring the market’s major topologies. This gives designers the flexibility to select the right PIM for the power conversion stage of ultra-fast DC charging or energy storage system (ESS) applications. To accelerate the design cycle, ON Semi also provides designers with advanced PLECS models through a self-service piecewise linear electrical circuit simulation (PLECS) model generator and application simulation using the portfolio’s elite power simulators.

For each module, ON Semi uses dies from the same wafer to ensure more consistent reliability, allowing designers to avoid the challenges of obtaining different performance within the same system that can occur when using discrete devices from different suppliers. It can be prevented.​
