Trusted semiconductor solutions for light electric vehicles (LEV)

Overview

Fueling the evolution of light vehicle electrification

As a leader in power semiconductors, Infineon strives to enable the most efficient, reliable, and smart solutions for e-mobility, Minimobility and Micromobility markets. Keeping up with the latest market trends worldwide, Infineon prepares for the ramp-up of all forms of light electric vehicles, such as:

Micromobility - electric bicycle (e-bike), electric kick-scooter
Electric powered 2/3 wheelers (ePTW) - e-moped, e-scooter, e-rickshaw, e-motorcycle
MicroEV – electric microcars, low-speed electric vehicles (LSEV), neighborhood EV (NEV), electric quadricycle
Other electric transporters (e.g. e-forklift, e-golf cart, e-ATV) with less than 200V batteries

Contrasting to automotive (passenger car) requirements, L-category (light) vehicles (though often also on-road) require different sets of safety and qualification standards. As an example, the newest motorcycle standards place more responsibility on the operator rather than the vehicle itself to mitigate risks. Infineon considers mission profiles of different end applications and offers suitable non-automotive and automotive components for this wide range of use cases.

Different from the traditional vehicles with internal combustion engines, these types of vehicles are powered by battery technology with bus voltage ranging from 28V to 168V. The commonalities among these different types of LEVs are motor inverter/drives, battery management systems, battery charger/battery charging station/battery swapping station. Additionally, light electric vehicles (LEVs) house increasingly popular smart features and electronics made possible due to their larger battery sizes.

Battery Management

Accurate, safe, and secure battery management system

The battery module with battery management systems is a crucial sub-system of any electric vehicles, it drives the performance of the vehicle in terms of top torque and kilometer range. A highly efficient battery management system in a light electric vehicle will utilize the lowest drain-source on-resistance OptiMOSTM and StrongIRFETTM MOSFET for maximum short circuit current capability and lowest continuous operation conduction losses. Infineon offers wide range of products for battery protection, monitoring, and cell balancing, such as the PSoC 4/6 microcontroller families.
