Cost estimates and revenue model for a public charging station
Cost estimates and revenue model for a public charging station The Government of India recently issued a notice entitled “Electric Vehicle Charging Infrastructure – Reg. Regulations and Standards”. Cost estimates and revenue model for a public charging station The availability of an adequate charging infrastructure is considered one of the most important prerequisites for an accelerated introduction of electric vehicles in the country.

Cost estimates and revenue model for a public charging station Accordingly, the establishment of public charging stations (PCS) has been authorized and each person / facility is free to install public charging stations, provided the stations meet specified technical and performance standards A PCS must have the following Minimum infrastructure, as described in the notification: Cost estimates and revenue model for a public charging station
Each charging station must have at least three fast chargers: a CCS, a CHAdeMo and a Typ2 AC. While the first two should run on 50kW / 2001000V, the Type2 is 22kW / 380480V. In addition, the charging station will have two trickle charging points: a Bharat DC001 (15 kW / 72 200 V) and a Bharat AC001 (10 kW / 230 V).
Cost Estimates and Revenue Model for a Public Charging Station A typical 50 kWh DCFC costs more than Rs 1.5 million. Since electric cars currently sold in India cannot be charged above 1 ° C and the batteries have a capacity of 11 kWh to 25 kWh, an investment in DCFC of more than 25 kWh would generate unattractive returns unless manufacturers to bring battery electric cars to the market that can be charged. quickly with DC output in the range of 400-500V or higher.

Charging standards applications:
IS: 170171 published by BIS in August 2018 recommends both CCS2 and CHAdeMO. In 2017, a committee formed by the Department of Heavy Industries (DHI) issued the Bharat charger specifications for AC and DC chargers: Bharat EV Charger AC001 and DC001.

BIS has agreed to maintain these standards that support electric vehicles currently operated in India. These are expected to disappear when new electric vehicles come onto the market with batteries that can be rapidly charged with DC power in the range of 400-500V or more.

All standards will coexist in India: CCS2, CHAdeMO and Bharat chargers. Tesla cars will use the CCS standard when launched in India, according to recent reports.
Two-wheelers come with small batteries, which in many cases can be taken out and taken home / offices / shops and recharged using standard electrical outlets. or it can be connected to each PCS. Two-wheelers come with small batteries, which in many cases can be taken out and brought home / offices / shops and recharged from normal electrical outlets; or they can be connected to each PCS.
Tricycles are ideal candidates for battery changes. In this scenario, batteries can be charged in a large industrial facility, and charged batteries are trucked to trike concentration locations where a tricycle operator can exchange the used battery for a fully charged one. Alternatively, technology owners can install changing stations on a PCS. 3wheelers can also be loaded in each PCS.
Buses with battery sizes> 100 kWh would be sold with proprietary charging standards recommended by the battery manufacturer. These batteries will cost several million rupees and it is not recommended to charge them from a PCS. Bus operators install chargers supplied (or recommended) by the bus manufacturer at bus stations and bus stations as needed.
Current electric car models are supplied with different battery sizes: from 11 kWh (Mahindra e20) to 40 kWh (Nissan Leaf) to> 90 kWh (Tesla Model S). These electric vehicles need DCFC for fast charging. The whole question of EVSE interoperability for different EV models is essentially limited to cars. In India, only Mahindra Electric and Tata Motors have launched electric cars so far.
The current batteries in these cars are not designed to charge above 1°C. Electric car launches can be slow as individual buyers can observe the space and move around cautiously, as in other regions. Taxi fleet operators, government agencies, public sector companies and large corporations await the first push for electric cars.

Cost Estimates for a PCS:
The Capex and Opex of a PCS with a minimum infrastructure required by the GoI message are estimated as follows:
The cost of the exchange station is considered to be borne by the owner of the exchange station technology. PCS offers space for an exchange station for a margin when it comes to selling electricity.
Land rent is assumed to be low under the Delhi Electric Vehicle Policy to provide minimum rental land to charging infrastructure providers.
Revenue estimate:
The sales forecast for the PCS business is calculated in the following table under the following assumptions:
20 hours of load in 30 days / month1. 20 hours of load for 30 days / month. Capacity Utilization Factor (CUF) of public charging stations (PCS) configuration with 15% for year1, 25% for year2, 40% for year3, 65% for year4 and 85 % for year5 (optimistic scenario).
The electricity tariff for DISCOM is considered to be passed on to the consumer. A margin of 2.5 rupees is taken into account in the electricity tariff in scenario A. A margin of 3 rupees in the first and second year, 2.5 rupees in the third and fourth years and 2 rupees in the fifth year the year of the seasons is taken into account in scenario B.
EVSE management software fee considered at 10% of the net margin of the electricity tariff. As can be seen in Tables 1 and 2, for the initial investment of 2.95 million rupees for the creation of a PCS is the accumulated net return in 5 years is 1.77 million rupees in the scenario A and Rs 1.53 million in scenario B. In both cases there is little or no benefit for third parties to establish and operate PCS. If you charge a margin greater than Rs 3, the EV rate is the same as the commercial electricity rate.
In the current scenario, the individual / corporate PCS business is not profitable. The government can refrain from encouraging third parties to install public charging stations to accelerate the introduction of electric mobility.
However, in the case of Delhi, under the Delhi Electric Vehicle Policy, GNCTD will provide a capital grant to cover the cost of chargers and installation costs. Considering the cost estimates in Table 1, IRR is an attractive investment option for the construction of a public charging station in Delhi with a 100 percent subsidy for charging devices.
