India’s rapidly expanding network of electric-vehicle chargers still faces a host of technical and deployment challenges. According to one recent report, a significant gap remains between the infrastructure currently available and the charging stations that could be needed as EV adoption increases. The challenges with the charging infrastructure extend beyond simply increasing the number of chargers and include charger reliability, power capacity, grid connectivity and technical standardisation.
Non-Functional EV Chargers Highlight Reliability Challenge
Some common issues include non-operational chargers. EV chargers can be installed but become non-operational or unavailable due to communication issues, power failures, equipment failures, and poor maintenance. To maximise charger uptime, real-time monitoring, diagnostics, remote fault detection and maintenance are needed.
India Needs More Heavy-Duty and Highway Charging
The charging requirements of electric cars, buses and commercial vehicles all differ. Heavy-duty electric vehicles, in particular, will need high-power charging systems that can deliver a lot of energy in a short period of time, making high-powered chargers, grid connections, thermal management and power-electronics systems critical areas for research and development.
Standardisation Can Improve EV Charging Compatibility
Another important challenge is the technical inconsistency of the implementations of charge points on the market. Standardised communication protocols, connector types, charging profiles and interoperability requirements can enable chargers to work more harmoniously with different EVs and charge networks.
The charging ecosystem can be further optimised through the use of smart charging technologies. Load management, real-time load monitoring, dynamic power distribution and solar integration can enable chargers to make more efficient use of available grid capacity.
