Inside the CCS2 Handshake: How ISO 15118 Controls Every Fast Charge Session

Before a single electron moves from a CCS2 charger to your car, the two devices exchange authentication messages, negotiate charging parameters, and verify safety state over a Power Line Communication channel running at 500 kbps on the control pilot pin. ISO 15118-2 defines every step — and understanding it explains every failed session, every 'communication error', and why V2G is not yet possible on Indian infrastructure.

What DC Fast Charging Does to Your Battery: The Physics Indian EV Owners Need to Know

Every DC fast charging session is a controlled trade-off between speed and longevity. The BMS is running real-time calculations to keep charging fast without permanently plating lithium metal onto your anode. Understanding lithium plating, the temperature interaction with India's climate, and why LFP handles fast charging differently than NMC changes how you plan long-distance travel.

India's EV Charging Standards: CCS2, Bharat DC001, and the Connector Wars

India mandated CCS2 for four-wheelers while keeping Bharat DC001 for three-wheelers and two-wheelers — a split that was not a compromise but a deliberate segmentation. Understanding AIS-138, why CHAdeMO lost, and what BIS certification actually means helps you navigate India's fragmented charging landscape with precision.

How EV Charging Actually Works: AC, DC, and Why It Matters for India

When you plug your EV in at home, you are not directly charging the battery. You are powering a converter inside the car. Understanding this one fact unlocks everything confusing about charging speeds, connector types, and why the Rs 25,000 home wallbox is one of the best upgrades an Indian EV owner can make.
