Electric buses drive sustainable urban mobility with zero-emission transport and high efficiency. APAR's advanced cable harnesses provide reliable high-voltage connectivity for EV buses, powering key systems in this shift.

A key milestone: Prime Minister Mr. Narendra Modi flagged off 200 JBM Eco Life electric buses under the PM e-Bus Sewa Scheme, deployed in Guwahati (100 buses), Bhavnagar (50), and Nagpur (50). These 9-meter low-floor, air-conditioned buses feature CCTV, automatic doors, and accessibility for seniors and disabled passengers. As a valued strategic partner to JBM Auto Limited, APAR is proud to contribute to the execution and supply support of 3,550 cable harness for 3550 electric buses across multiple platforms such as 12M Coach, Indigo, and 9M LF Tarmac models.

APAR's EV Harnesses for Electric Buses

APAR produces advanced automotive wiring harnesses and cables for electric buses at IATF-certified facility in Khatalwada, Gujarat. These include custom E-beam irradiated cables for high-voltage EV powertrains, battery management, and plug-and-play solutions meeting OEM specs for safety, durability, and zero-loss transmission.

Key Features

  • Designed for EV buses via partnerships with JBM Solar (harnesses supplied) and Olectra Greentech (approved).
  • Supports ‘Make in India’ with R&D for passenger EVs, chargers, and heavy-duty applications; strong demand in charging cables and EV harnesses aligns with trends.
  • Flame-retardant, 25+ year lifespan, tailored for India's electrification push.

Market Position & Share in India

APAR is a first mover among Indian cable makers in EV harnesses, pioneering since 2023. Total market projected at 90% CAGR, driven by EV and engine harness expansion. APAR holds 8% of organised cables market (6th largest). Supplies target ~10,000+ annual tenders under PM-eBus Sewa.

EV adoption surges: FY 2024 – 25 registrations hit 1.97M units (+16.9% YoY from 1.68M). Electric 4W: >1 lakh (+18.2% YoY); e-2W: 12 lakh (+21.2%); e-3W: ~3.5 lakh (+10.5%). Policies like Electric Mobility Promotion Scheme (Apr – Sep 2024), PM e-Drive, and PM e-Sewa fuel growth with new models.

Why Harnesses Matter in EVs

Harnesses form the electrical backbone of electric buses, handling 400-800V DC systems amid vibrations, 105°C temperatures, and 500A+ currents. Unlike conventional wiring, they use XLPE insulation for dielectric strength and LSZH for safety.

APAR's harnesses meet AEC-Q100 reliability, IP67 protection, and ISO 6722 standards. They power PM e-Bus Sewa deployments and international fleets in Singapore and Australia.

Applications of APAR Automotive Wire Harnesses

APAR harnesses integrate into EV bus body, chassis, and power systems for optimal performance.

  • Reduced installation time and shorting risk via modular design.
  • Exceptional durability under thermal cycling and vibration (ISO 16750).
  • Lightweight for efficiency in fleet operations.

APAR's Tailored EV Harness Solutions

APAR excels in high-voltage harnesses for critical EV paths:

  • PDU to MCU (+/-): Shielded for EMI-free power transfer.
  • MCU to Traction Motor: High-current with flexible silicone sheathing (10x bend radius).
  • BCS to PDU: Fast charging (CCS2) with 150kW thermal management.
  • PDU to Inverter: Orange-jacketed (ISO 6469-3) for safety.
  • HVSS to ACM & PSM: Fail-safes with contactors and fuses.

Features include modular builds, aluminium-clad copper for weight savings, and MTBF >1 million km. JBM's fleet: 300M+ electric km, 1 billion+ passengers, 1 billion+ kg CO₂ averted.

Real-World Impact: From Indian Streets to Global Routes

APAR's solutions demonstrate proven efficacy in high-profile environments. Within India, they underpin national initiatives like the PM e-Bus Sewa Scheme, facilitating the transition from aging diesel fleets to sustainable alternatives that enhance last-mile connectivity in urban centres. Additional applications include IndiGo's ground support operations, projects at iconic locations, and large-scale city deployments.

On the international stage, APAR harnesses enable EV bus fleets in Singapore's tropical climate and Australia's rugged terrains, performing reliably across temperature extremes from -40°C to +125°C. APAR contributes to India's ambition of achieving net-zero greenhouse gas emissions by 2070 through effective public-private partnerships.

The APAR Edge: Innovation Meets Reliability

APAR ensures quality via in-house tests (ISO 16750 vibration, 5kV breakdown). Innovations like 30% flexier thermoplastic elastomers and AI routing minimise voltage drop.

APAR remains committed to excellence, innovation, and quality, playing a pivotal role in sustainable public transportation solutions across India and global.
