Light electric vehicles
The evolution of light vehicle electrification
As a leader in power semiconductors, Infineon strives to provide the most efficient, reliable, and smart solutions in the market. Keeping up with the latest market trends worldwide, Infineon prepares for the ramp-up of the following, including but not limited to, types of light electric vehicles.
- Micromobility - electric bicycle, electric kick-scooter
- Electric powered 2/3 wheelers (ePTW) - e-moped, e-scooter, e-rickshaw, e-motorcycle
- MicroEV - Electric Microcars, low-speed electric vehicles, neighborhood EV (NEV), electric quadricycle
- Other electric transporters (e.g. e-forklift, e-golf cart) with less than 200V batteries
Contrasting to automotive requirements, these applications (though also on-road) require different sets of safety and qualification standards which place more responsibility on the operator rather than the vehicle itself to mitigate the risk. Many of Infineon's non-automotive and automotive offerings are created targeting these applications.
Different from the traditional vehicles with internal combustion engines, these types of vehicles are powered by batteries with bus voltage ranging from 28V to 168V. The commonality among the electric light vehicles is motor drives/inverters, battery management systems, battery chargers/stations, and the increasingly popular smart features and electronics made possible due to their larger size batteries.

The battery module is a crucial sub-system of all light electric vehicles that drives the performance of the vehicle in terms of top torque and kilometer range. A highly efficient battery management system utilizes the lowest drain-source on-resistance OptiMOSTM and StrongIRFETTM MOSFET for maximum short circuit current capability and lowest continuous operation conduction losses. Details about battery protection, monitoring, and cell balancing utilizing Infineon offerings, such as TLE9012 and PSoC 4 microcontroller family can be found. |
