BESS-buffered EV charging decouples charger power from grid capacity, enabling 150-350 kW DC fast charging on weak 30-50 kW connections. Deploy fast charging in Tier 2/3 cities and highway corridors where grid upgrades would take years.
EV sales are surging. Charging infrastructure is not. The bottleneck isn't demand, it's the grid.
India sold 19 lakh EVs in 2024, a 19% year-on-year surge, with electric car sales jumping 77% in 2025. The PM E-DRIVE scheme has allocated INR 2,000 crore for 88,500 new charging sites. But the grid can't deliver the power these chargers need. The EV-to-charger ratio stands at 1:235 against an ideal of 1:20. Charge point operators who can deploy fast charging anywhere, now, without waiting 18 months for a grid upgrade, will capture this market.
150-350 kW DC fast chargers need 500+ kVA from the grid. Most locations outside metro cities have 30-50 kW. Do the math.
A single 150-350 kW DC fast charger demands a 500+ kVA grid connection. Most Tier 2/3 locations have only 30-50 kW available.
New HT connections cost INR 50-80 lakh, take 6-18 months to install, and require land for substations, killing project economics.
Simultaneous fast-charging sessions create demand spikes that attract punitive peak demand charges, eroding station profitability by 40-60%.
Major highway corridors have stretches of 100+ km with no fast charging, not because there is no demand, but because there is no grid capacity.
Slow grid charge. Fast vehicle discharge. It's that simple.

Rapid burst to vehicle
The BESS absorbs energy slowly from the grid (or solar) over hours, then dispenses it rapidly to vehicles on demand. The grid never sees the 350 kW spike, it only sees a steady 30-50 kW draw.
Hardware gets energy in and out. Software decides when, how much, and for whom, turning a battery into a revenue-optimizing platform.
Queues and prioritizes vehicles intelligently, optimizes BESS state-of-charge in real time to ensure charger availability even during peak hours.
Maximizes solar carport utilization and minimizes grid draw during peak tariff hours. Automatically shifts load to stored solar energy when rates spike.
Prevents simultaneous charging sessions from creating demand spikes. Keeps contracted demand low and station economics healthy month after month.
Optimizes overnight bus and truck charging sequences to minimize grid connection requirements. Charges 20-50+ vehicles from a single connection.
APIs that integrate seamlessly with OCPP-compliant charge management platforms. Plug into existing CPO software stacks without vendor lock-in.
Per-session cost tracking, margin optimization, and utilization dashboards. Know exactly which chargers, time slots, and tariff windows drive profit.
Cloud-based BESS health monitoring with predictive maintenance alerts. Track cell-level temperatures, SOC, cycle counts, and degradation curves 24/7.
Every Ingro BESS ships with our cloud-connected EMS platform. Firmware updates, algorithm improvements, and new features are delivered over-the-air, your charging station gets smarter every month, not just the day it was installed.
Whether you're a highway concessionaire, a mall operator, or a transit authority, there's a configuration built for your use case.
150-350 kW charging every 50 km
Deploy high-power DC fast chargers along national highways where grid infrastructure is weakest. BESS buffers enable 350 kW output from 30-50 kW grid connections, turning roadside dhabas and fuel stations into EV charging hubs.
Grid-independent charging in city centers
Transform mall parking lots, commercial complexes, and transit hubs into solar-powered EV charging destinations. Solar carports generate energy, BESS stores it, and smart software ensures every vehicle gets the fastest possible charge.
20-50+ buses from one connection
City transit authorities and logistics operators need to charge entire fleets overnight from a single depot connection. Fleet Scheduling AI sequences charging across vehicles, ensuring every bus is ready by 5 AM without ever exceeding contracted demand.
Purpose-built BESS solutions for charge point operators, fleet operators, and EV charging startups.
Deploy 150-350 kW DC fast chargers on 30-50 kW grid connections. BESS bridges the power gap invisibly, the driver sees only a fast charge.
Skip the INR 50-80 lakh HT connection upgrade. A containerized BESS deploys in weeks at a fraction of the cost of grid augmentation.
Solar carports + BESS reduce per-unit energy costs by 30-40% and qualify stations for green energy incentives under state EV policies.
Flatten demand profiles to keep contracted demand low. Prevent the punitive demand charges that make unmanaged fast charging commercially unviable.
BESS provides backup during grid outages, ensuring charging continuity. Your station never goes dark, even when the grid does.
Tier 1, Tier 2, Tier 3, highway, rural, if there is a road and a 30 kW connection, you can deploy world-class fast charging with Ingro.
A streamlined 4-step process to deploy BESS-buffered charging infrastructure at any location, regardless of grid capacity.
Assess available grid capacity, solar potential, expected EV traffic, and charging patterns to determine optimal BESS and charger sizing.
Design the integrated BESS + charger + solar system with smart power management that maximizes charger availability within grid constraints.
Install containerized BESS, mount solar carports, deploy chargers, and integrate with your CPO management platform via OCPP APIs.
AI-driven optimization manages sessions, grid draw, and solar storage. Scale by adding chargers or BESS modules as demand grows.
