Dhoot Transmission Limited builds four electronics families in-house

Dhoot Transmission Limited is building four electronics product families around its wiring-harness core through a 237-person research, design and engineering network as of March 2026, with current products including battery packs, sensors and charging guns and pipeline products including battery-management systems, advanced driver-assistance systems and high-voltage harnesses.

How does Dhoot Transmission develop products in-house?

Dhoot Transmission develops products from concept to serial production through 237 research, development, design and engineering employees and four engineering and design centres. Its process begins with co-development alongside original equipment manufacturer, or OEM, engineering teams, followed by in-house design and simulation using global design tools.

The stated development chain includes rapid customised prototyping, in-house reliability and durability testing, tooling engineering, bill-of-materials customisation and production-line setup. After serial production begins, Dhoot Transmission says it places plants near customers and applies continuous value analysis and value engineering, or VAVE, linking design work with local industrialisation.

The four centres are in Pune and Chhatrapati Sambhajinagar for electronics, Bengaluru for wiring-harness components, and Bengaluru for electronics ML. Dhoot Transmission also says two international technology partners support electronics research and development, while its research priorities are new development, value engineering and technology absorption.

What are Dhoot Transmission’s four product families?

Dhoot Transmission’s four product families are safety-critical electronics, battery packs and electric-vehicle electronics, powertrain-agnostic electronics and premiumisation, and connection systems, with wiring harnesses as the core. The harness portfolio covers low-voltage, high-voltage and battery harnesses for two-wheelers, three-wheelers, commercial vehicles and off-highway vehicles.

Safety-critical electronics currently include anti-lock braking system, or ABS, sensors, lean-angle sensors, gear-position sensors and flashers. The pipeline and longer-term list adds advanced driver-assistance system, or ADAS, cameras and electronic control units, or ECUs, alongside access systems and tyre-pressure monitoring system, or TPMS, products.

Battery and EV electronics currently include a 48-volt traction pack, a 12-volt auxiliary pack and a charging gun. Pipeline products are an off-board charger, a direct-current-to-direct-current, or DC-DC, converter, and 12-volt and 48-volt battery-management systems, or BMS, which Dhoot Transmission also identifies as electrification research areas.

Which Dhoot Transmission products are already in production?

Dhoot Transmission has products in production across its four families, while higher-content electronics and additional high-voltage systems remain in pipeline or longer-term categories. For an electric-scooter application, it identifies low-voltage main wiring harnesses, high-voltage harnesses, charging guns and connectors, battery packs, switches, ECUs, ABS or wheel-speed sensors, and USB Type-C chargers as in production.

The scooter pipeline includes a 12-volt BMS, DC-DC converter, off-board charger and TPMS sensors. An ADAS camera and controller are in the joint-venture pipeline, a separate designation from products already commercialised by Dhoot Transmission.

In powertrain-agnostic electronics and premiumisation, current products include start-stop switches, relays, EV power relays and USB chargers, while head-up displays, emergency-call functions and further switches are later-stage items. Connection systems currently cover connectors, terminals, fuses and junction boxes; power-distribution units, or PDUs, battery-distribution units, or BDUs, and commercial-vehicle or passenger-vehicle high-voltage harnesses are pipeline products.

How is Dhoot Transmission increasing EV content?

Dhoot Transmission is expanding potential EV content from wiring into batteries, charging, conversion electronics, sensors and cameras, and EV represented 31% of consolidated revenue in Q2 FY27. That was up from 27% in Q1 FY27, 24% in FY26 and 16% in FY24, although Multilink was consolidated from Q1 FY27.

Management says about 95% of the portfolio is EV-focused or powertrain-neutral. In an electric scooter, the current content includes a 12-volt control-and-signal harness, a high-voltage traction-and-charging cable, a battery pack and a charging connector; planned BMS products, chargers and converters would add electronics around that connection architecture.

Dhoot Transmission disclosed two powertrain-battery manufacturing facilities at Hosur and Pune, with production planned to commence in June 2027 and September 2027, respectively. It also listed powertrain-battery manufacturing for a new south India-based leading OEM, with start of production stated as June 2026; neither disclosure gives production volumes.

What does the Ride Vision joint venture add?

Dhoot Transmission says its proposed 67:33 joint venture with Ride Vision would add camera-based safety and control devices, including cameras, controllers, alert displays or human-machine interfaces, harnesses and cables. The company places the ADAS camera and controller in its joint-venture pipeline rather than among its existing products.

The identified applications include two-wheeler advanced rider-assistance system, or ARAS, alerts, EV two-wheelers using cameras and software, forklift human detection, commercial vehicles and the aftermarket. Dhoot Transmission reports more than five customer engagements across multiple segments and says proof-of-concept-level discussions with EV players were ongoing.

Dhoot Transmission states that about 90% of ADAS and ARAS is imported today and describes the venture as a localisation route using its harnesses, controllers and OEM access. The presentation says programme milestones will be added once cleared, leaving commercial timing unresolved.

How has Dhoot Transmission’s product mix changed?

Dhoot Transmission’s revenue mix has shifted toward batteries, electronics and components, which reached 31% of revenue in Q2 FY27 from 18% in FY24. Wiring harnesses correspondingly fell to 69% of revenue from 82% over the same period.

The Q2 FY27 increase followed the Multilink acquisition, which Dhoot Transmission says is involved in sensors, relays and other electronic products and contributed for a full quarter. The company also says EV-related components for Hero started because of the Multilink acquisition.

Conclusion

Dhoot Transmission is using its wiring-harness base to add safety devices, EV power products, premiumisation products and connection systems. Its 237-person engineering organisation, four centres and two technology partners support a stated in-house path from OEM co-development through testing and local serial production, while non-harness products reached 31% of Q2 FY27 revenue.

The next disclosed milestones are the new OEM powertrain-battery programme scheduled for June 2026 and battery-facility production at Hosur and Pune in June and September 2027. Management’s next updates on cleared Ride Vision programme milestones and the more than five customer engagements will indicate how the joint-venture pipeline advances.
