Rolfe Motors & Energy Private Limited is a Delhi-based advanced energy technology company designing, assembling, and deploying high-performance lithium battery systems and full-stack energy storage platforms for India's electric mobility and grid-scale energy sectors.
Founded and led by engineers and entrepreneurs, we operate two distinct technology verticals under the JT-ONE master brand:
JouleTap — our electric vehicle energy division — engineers lithium battery packs (NMC and LiFePO4 chemistries) and smart charging systems for electric two-wheelers, e-rickshaws, golf carts, and electric shuttle buses. Every JouleTap product is designed for Indian duty cycles, climate conditions, and total cost of ownership.
JouleTower — our battery energy storage platform — delivers full-stack BESS solutions from 10 kW to 500 kW for C&I, institutional, and infrastructure clients. The JouleTower platform integrates cell-level engineering, power conversion, energy management, and remote monitoring into a single, performance-guaranteed system — built on the principle that every joule counts.
Our manufacturing operations are based in Greater Noida, with corporate headquarters in New Delhi.
We partner with Tier-1 global cell and component suppliers and bring deep in-house expertise across battery chemistry, BMS architecture, PCS selection, EMS integration, and lifecycle O&M — capabilities that allow us to serve clients not just as a product vendor, but as a long-term energy infrastructure partner.
