Want both? Light electric vehicle charging solutions balance efficiency and safety!

Amid the general trend of vehicle electrification, the light electric vehicle (LEV) market segment is gradually emerging. According to relevant data, tens of millions of electric two-wheelers have been sold and used worldwide.

Light electric vehicles (LEVs) are low-power electric vehicles with a power range of 1,000W to 10,000W and a voltage range of 24V to 72V . Examples include electric scooters (stand-up, self-balancing, and foldable), electric bicycles, electric rickshaws, and other types of electric three-wheelers.

As light electric vehicles become increasingly popular in daily life, how to charge them quickly and efficiently has become a key issue. In this context, high-power chargers have emerged, bringing both efficiency and speed to the vehicle charging process.

In terms of circuit design, Avnet's LEV charger solution not only has constant output voltage and current control feedback functions, but also adopts an advanced isolated PFC+LLC topology to optimize the charging efficiency of 72V and 48V batteries and provide higher regulation capabilities.

The PFC controller uses Infineon's ICE3PCS01GX product , which is efficient, stable and reliable and can significantly improve the power factor and efficiency of the AC/DC converter.

For the LLC part, the ICE2HS01GX chip was selected , which has a built-in synchronous rectification driver, supports a switching frequency range of 30kHz to 1MHz, and has adjustable switching frequency and high-accuracy frequency setting.

In addition, this charger solution also has many excellent technical parameters:

• Its input AC line frequency is 47Hz to 63Hz;

• Under full load, its input A.THD (total harmonic distortion) is less than 3.5%, the power factor is greater than 0.97, and the power conversion efficiency can reach 92%, which greatly reduces energy loss and improves charging speed;

• Furthermore, this solution also supports Iso/Non-Iso CAN, RS485 and other communication protocols, making it easier for users to conduct remote monitoring and management.
