EV, Hybrid and Mobility Systems Engineering

UK engineering services for EV, hybrid and off-highway mobility programmes. PTL supports teams where integration, packaging, repeatability and system behaviour matter as much as any individual component. Including EV battery pack engineering, in-wheel motor architecture, eBike system development and multi-domain interface work.

Why teams engage PTL for mobility systems

Mobility programmes often have multiple levels of complexity. Failures often occur when the interfaces between mechanical, electrical, thermal and control systems behave differently from boundary conditions which have been assumed for single components or subsystems.

PTL is engaged when integration, packaging and repeatability are the real risks rather than any single component in isolation. We typically support projects from concept trade-offs and architecture definition into detailed design and validation planning. From there, we support prototype development, correlation and scale-readiness inputs. That work is informed by programme experience across eBike system development, EV battery-pack substantiation and electric-motor architecture studies.

We support teams working on

  • EV, hybrid and off-highway platforms
  • Electrification packaging and system architecture
  • Electric motor and inverter-related development
  • eBike and light electric vehicle system engineering
  • In-wheel motor architecture and integration studies
  • Multi-domain interfaces across mechanical, electrical, thermal and control systems

eBike system upgrade programme

Proven Expertise

  • Electrification experience across EV battery pack engineering, eBike development and in-wheel motor architecture studies
  • Evidence-led support across packaging, interfaces and repeatability

Trusted Partnerships

  • We typically work under NDA, and all IP generated is assigned to our customers
  • Prototype-to-production support where validation, integration and scale-up need to be resolved early

Independent, Senior-Led

  • Independently owned, technology-agnostic — no parent group’s EV product roadmap or tied motor/battery route influencing the engineering recommendation
  • Senior specialists with direct programme history at Ricardo, Lotus, AVL, Maserati and related organisations, delivering the work directly rather than selling senior time and delivering junior time

Internationally Recognised

  • UK HQ with international client base
  • Support across EV, hybrid and off-highway programmes where system behaviour matters more than single-component performance

Recent mobility projects

We reduce mobility risk by understanding system behaviour across interfaces. This helps teams engineer repeatability before scale makes variability expensive.

CASE STUDY

Turning a Novel eBike Concept into a More Usable Product

PTL supported an eBike programme where control behaviour and rider feel needed to improve across real riding conditions. Through modelling, testing, calibration and wider system upgrades, the concept moved towards a more natural and repeatable user experience.

CASE STUDY

Clarifying Viable Design Routes for In-Wheel Motor Integration

PTL carried out concept studies for in-wheel motor and wider electrical system development where packaging, controls and integration had to be considered together from the start. The work helped clarify what was technically viable before greater time and cost were committed.

Frequently asked questions about EV and mobility engineering

Yes. PTL has carried out concept studies for in-wheel motor and wider electrical system development where packaging, controls and integration had to be considered together from the start. See also the dedicated Motors page.

Yes. PTL has supported eBike system development including controller, inverter, battery, firmware and calibration work across real riding conditions. Typical engagements target control behaviour, rider feel and system repeatability.

PTL focuses on the system-level and sub-system engineering that determines whether a vehicle programme succeeds, including powertrain integration, battery pack, motor architecture, thermal management and interface behaviour. Complete vehicle engineering from a clean sheet typically sits with larger OEM-scale partners, and PTL works alongside those teams.

Concept to Prototype for the eBike Market

We worked very closely with PTL in developing and licensing CVT drive concepts for the eBike market.

PTL were an outstanding partner – Applying advanced simulation techniques, developing innovative concepts and control software, and realising hardware prototypes. They were a responsive, reliable, and agreeable partner who I would thoroughly recommend.
