Tourist, pilgrim & public sites
AC and light-EV points sized for visitors who stay an hour or more.
Hospitals & campuses
Staff, visitor and fleet charging within your premises, metered separately where it pays.

Safe clearances and approvals around fuel dispensers, designed in from the first drawing.
Charger types
Which charger for which vehicle
Match the charger to the vehicle and to how long it stays.

Battery buffer
Fast charging with a battery buffer
Cheapest 09:00–16:00 Dearest 06:00–09:00 · 18:00–22:00
Fill steadily
The grid, or solar, charges the battery within your existing connection.
Boost on demand
When a vehicle plugs in, the charger draws on the grid and the battery together.
Refill between sessions
The battery recharges between sessions, ideally in cheaper hours.
Whether a buffer beats a bigger connection depends on charger use, your tariff and upstream costs, so we model both side by side.
Tamil Nadu’s EV tariff is cheapest from 9 am to 4 pm (TNERC Tariff Order No. 6 of 2025), so a battery can store daytime energy for evening charging.

Rules
Charging station rules
As of
Setting up a charging station is de-licensed: anyone can do it by following the Ministry of Power guidelines.
DISCOMs must connect within 3 to 30 days depending on the area (90 if the network needs extending) and offer LT connections up to 150 kW.
Service charges at public stations are capped until 31 March 2028 (AC ₹3–4, DC ₹11–13 per kWh, before GST) and must be displayed.
CEA safety rules ban adaptors and extension leads, require earth-continuity monitoring, and make owners keep test records for at least 7 years.
Tamil Nadu’s EV tariffs (LT-VII, HT-V) are cheapest from 9 am to 4 pm, and smart ToD meters are mandatory.
Public funding for chargers
In force · to 31 Mar 2028PM E-DRIVE funds public charging on government-proposed sites until 31 March 2028:
- Government premises with free public access: 100% of upstream infrastructure and chargers.
- Public-sector sites such as railway, metro and bus stations, airports, toll plazas and public-sector fuel outlets: 80% of upstream, 70% of chargers.
- Other locations, and battery swapping or charging stations: 80% of upstream.
Nodal agencies run the stations or pick operators by bidding, so private hosts usually can’t apply directly.

Questions about EV charging
No. It’s a de-licensed activity under the Ministry of Power’s 2024 guidelines; you need a DISCOM connection and the Electrical Inspectorate’s safety clearance.
Often, yes. Charging within HT premises may be billed at the premises’ own tariff, or you can take a separate EV service; we’ll work out which suits you.
Yes. We connect chargers over OCPP to the charging software you choose; roaming across apps runs through your network partner.
Yes, on the power side: site power, fire-safe enclosures and O&M, following the Ministry of Power’s January 2025 swapping guidelines. We don’t run a swapping brand.
A DC pillar needs a small plinth and clearances, with the vehicle within 5 m of the charging point; AC units can be wall-mounted. Basement and fuel-station sites need extra approvals.
