EV & e-mobility: choosing the components
An electric vehicle — from a two-wheeler to a passenger car — divides into eight blocks: traction motor drive, sensing, the power stage, battery management, charging, the instrument cluster, connectivity, and the connectors and protection around all of it. This guide shows which J.P. Electronics manufacturer lines serve each block, with the two-wheeler and three-wheeler platforms that dominate the Indian market in mind.
Which of our lines serves each block?
| Block | Our lines | What decides the choice |
|---|---|---|
| Traction motor drive | Geehy Allegro MicroSystems Novosense Microchip | Two-wheeler and three-wheeler BLDC or PMSM, torque profile, hill hold |
| Phase current & position sensing | Allegro MicroSystems Novosense | FOC bandwidth, isolation, rotor position accuracy |
| Power stage | Navitas Taiwan Semiconductor Good Ark Viitor | 48 V to 96 V bus for 2W/3W, higher for 4W; switching frequency and thermals |
| Battery management | Microchip NXP Novosense Ramxeed | Cell count, balancing, isolated measurement, trip data logging |
| On-board & off-board charging | Navitas Chipown On-Bright Weltrend | GaN density, PFC, connector standard |
| Instrument cluster & HMI | AV Display Yeebo Same Sky Brightek | TFT cluster, indicators, buzzer, ambient light |
| Connectivity & tracking | Quectel Allystar | LTE telematics, GNSS tracking, theft alerts |
| Connectors, passives & protection | CLAF KLS CCTC Bourns Bel VinaTech | Vibration, creepage, surge, ride-through |
What is different about two-wheeler and three-wheeler EV design?
Cost and integration. A 48 V or 60 V bus keeps the power stage simple and lets one controller board carry the MCU, gate drive, sensing and telematics together. The volumes are enormous and the BOM is squeezed hard, which is where a card that spans both established and second-source manufacturers earns its place.
Where does GaN fit in an EV?
In the charger, first. GaN shrinks on-board and portable chargers dramatically at the power levels two-wheelers and three-wheelers use, and charger size is a selling feature. Traction inverters remain silicon or SiC for now.
