Battery Management System (BMS) in Electric Vehicles
A complete guide to how the BMS protects lithium traction packs, balances cells, and coordinates charging and regen in cars and two-wheelers.
On-Board Charger (OBC) in Electric Vehicles
How the OBC converts AC grid power to DC for the traction battery, typical power ratings (kW), efficiency, and differences between cars and two-wheelers.
Regenerative Braking in Electric Vehicles
How regen recovers energy to the battery, limits by SoC and temperature, and how one-pedal driving and blended brakes differ across EV categories.
EV Battery Pack: Structure, Modules, and Performance
How traction battery packs are built from cells to modules, voltage architecture, energy in kWh, and what buyers should verify for cars and electric two-wheelers.
LFP vs NMC in EVs: Chemistry, Range, and Charging Trade-offs
Compare lithium iron phosphate (LFP) and nickel-manganese-cobalt (NMC) families for EVs: voltage, energy density, cycle life, cold performance, and fast-charge behaviour.
EV Charger Explained: Wallbox, AC EVSE, and DC Stations
Understand what “charger” means in EV language: onboard conversion vs offboard DC, connector types, kW ratings, and safe installation for Indian homes and fleets.
DC Fast Charging for EVs: kW, Curves, and Battery Care
How DC fast charging delivers high kW to the pack, why power tapers, CCS and GB/T context, and how heat and SoC shape safe charging in India summers.
AC vs DC Charging in EVs: What Changes Onboard
Side-by-side view of AC and DC paths: where power is converted, how kW is limited, cost of installation, and when each mode fits daily and highway use.
Hub Motors in Electric Two-Wheelers: Design and Trade-offs
In-wheel and geared hub motor layouts for e-scooters and e-bikes: torque delivery, unsprung mass, efficiency, cooling, and maintenance implications.
Mid-Drive Motors in EVs: Placement, Gearing, and Efficiency
Mid-mounted motors on e-bikes and some light EVs: chain or gear drive to the wheel, torque multiplication, lower unsprung mass, and service considerations.
