On board chargers
The on-board charger is used to convert the AC power from the charging station to DC power to charge the battery. The on-board charger is typically integrated into the vehicle and is capable of accepting a range of AC input voltages and frequencies.
On-board chargers are an essential component of electric vehicles, providing the ability to recharge the vehicle's battery while it's parked. They convert the AC power from the electrical grid into the DC power that the battery can accept, and as such, they play a vital role in the operation of electric vehicles. In this technical application page, we will discuss the materials and adhesives that are commonly used in the construction of on-board chargers.
When constructing on-board chargers, it is essential to use materials that can withstand high temperatures, humidity, and mechanical stress. The device's high power and high-frequency circuitry require careful consideration of the electrical properties of the materials used, as well as their thermal properties. Here are some of the commonly used materials in on-board charger construction:
Epoxy resins: Epoxy resins are widely used in on-board charger construction for their excellent electrical and mechanical properties. They offer high mechanical strength, good thermal conductivity, and good resistance to temperature changes, making them an ideal choice for use in high-temperature environments.
Silicone adhesives: Silicone adhesives are often used in on-board charger construction for their excellent resistance to high temperatures, humidity, and UV radiation. They are also known for their low shrinkage and good thermal conductivity, making them a good choice for use in the high-power circuits in on-board chargers.
Potting compounds: Potting compounds are used to encapsulate and protect the electronic components in on-board chargers from moisture, dust, and other environmental hazards. They are often based on epoxy or silicone resins, depending on the specific application and desired properties.
In addition to these materials, on-board chargers may also contain capacitors, inductors, transformers, and other electronic components. The selection of these components also depends on the specific application and desired performance characteristics, including power handling, efficiency, and size.
On-board chargers are critical components of electric vehicles, and their construction requires careful consideration of the materials and adhesives used. Epoxy resins, silicone adhesives, and potting compounds are commonly used materials in on-board charger construction, providing excellent electrical, mechanical, and thermal properties. Careful consideration of the components used is necessary to ensure that the device meets the desired performance characteristics for the specific application.
