With India’s rapid embrace of electric vehicles, countless AC chargers are now in use across homes, businesses, and apartments. While these chargers make EV ownership accessible and affordable, most entry-level models remain cost-competitive by omitting advanced protection features. However, one critical local challenge can’t be ignored: India’s notoriously unstable grid voltage and frequent power fluctuations.
Unlike many developed countries, India’s power infrastructure is still in the process of evolving. Voltage can swing dramatically—from as low as 110V to highs well above 300V—even within a single day. Spikes, surges, and dips are far more common here due to unpredictable grid management and heavy loads on ageing transformers. For chargers, especially budget AC units, this increases the risk of overheating, charging inefficiency, costly repairs, or even total device failure.
Solution? Always integrate an external surge protector or a robust voltage stabiliser—right at the input to your charger. These devices are inexpensive compared to the cost of replacing a damaged charger (or an EV battery), and can be easily installed as a “plug and play” upgrade by a qualified electrician.
Benefits of a Surge Protector or Stabiliser for AC Chargers:
- Shield delicate charger electronics from high- and low-voltage events.
- Prevents damage from surges caused by lightning, grid switching, or overloads.
- Ensures consistent charging speeds and extends the lifespan of your charging equipment.
- Lowers overall maintenance and replacement costs for stations in high-fluctuation zones.
A one-time investment of ₹5,000–₹10,000 in a quality stabiliser or surge protector can save lakhs in long-term repairs and downtime. Whether you’re a household EV owner, a business, or running a franchise charging network, make surge protection a mandatory part of your installation.
Pro tip: Always choose stabilisers rated for EV-grade loads and ensure your installation is handled by a professional. This single step will future-proof your charging setup and give you peace of mind in India’s complex power environment.
