An electric vehicle (EV) power transformer is a device designed specifically to convert an alternating current (AC) source of energy for use in an electric vehicle.
This power source can be a utility grid or a local renewable energy source such as solar. The transformer works by changing the AC current from the power source into an appropriate voltage and current match suitable for powering the motor of the vehicle.
As well as allowing compatibility across different types of sources, EV power transformers are also capable of efficiently handling high levels of electrical load, thereby improving efficiency and safety.
In designing EV transformers, there are certain factors which must be taken into account such as peak voltage requirements, capacity for regulation, insulation levels against risk-causing spikes or surges in electricity and fault protection mechanisms.
These factors help to ensure that reliable operation can take place with minimal faults or incidents occurring during operation time.
In addition to this, when selecting components for EVs long-term performance should also be factored in along with cost considerations as performance expectations increase with complexity increasing investment requirements exponentially.
EV power transformers represent a key piece of technology needed to drive greater adoption of zero-emission vehicles worldwide by providing efficient sources and pathways for distributing electricity across electrified roadsides where it is used to propel vehicles.
As time progresses, the technology developed in this sector should become increasingly advanced allowing more seamless operation and better usability while improving safety.
The Global EV power transformer market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
ABB, a Swiss-based engineering company, has unveiled its new Fusegear family, a range of low voltage power transformers designed specifically for powering Electric Vehicles (EVs) and grid transformation operations.
The company says the new product family is the first ever offering from an industrial leader to offer three distinct solutions for power transformation in EV use cases.
The range includes ABB’s premium low-voltage fused disconnect switch (FDS), the industry standard DD7 compliant distribution panel set and a compact fuse board that acts as an all-in-one solution to allow easy connection of auxiliary charging points in various locations.
According to ABB, it is expected that the Fusegear family will contribute towards EV charging infrastructure flexibility and safety by offering customers greater choice in their power supply needs for on grid or off grid applications.
In addition, each product within the Fusegear series is easily installable with minimal technical expertise required; reducing time spent installing complex components by up to 70%, thus making it suitable even for novice users.
Siemens recently presented its range of EV charger transformer solutions. The offering covers all power ratings used in charging infrastructure up to 5000 kVA, single and three phase systems.
One example is the “Made-in-Germany” Siemens Prexform® enclosures for single and three phase wallbox or pedestal chargers that feature robust protection and short circuit withstand capability while maintaining a compact footprint of just 6m per kW of installed power output.
Furthermore, the company offers different transformer solutions suitable for applications such as urban installations with limited space, fast chargers with higher output ratings or even charging parks along highways that need extra flexibility when dealing with day-to-day operations.
