E-Rickshaw Engineering

Description

This E-Rickshaw eBook from 3D-LABS is written for engineers and students who want a clear, practical reference they can apply immediately.

E-Rickshaw Engineering is a practitioner-level engineering book covering e-rickshaw and e-cart design, and in particular the lead-acid to lithium-ion retrofit that now dominates the fleet. It works through the special vehicle category created under CMVR, the 2021 MoRTH retrofitment framework, pack and BMS selection for a 48 V/60 V platform, and the documentation a retrofit workshop must hold to stay legal.

What format does this book follow and what standards does it reference?

The book is organised as a retrofit project: assessment, design, build, test, and paperwork. Standards referenced include AIS-123 (Part 2) for electric propulsion retrofit kits, AIS-156 Amendment 3 for traction battery safety, CMVR Rule 2(u) defining e-rickshaw and e-cart, and the MoRTH 2021 retrofitment notification. Each requirement is stated with the clause, the test it implies, and the record the workshop must retain.

Why does a lead-acid to lithium retrofit need re-engineering rather than a swap?

The two chemistries differ in voltage window, internal resistance, charge acceptance and mass. The book shows the consequences: a lithium pack sits roughly 60 % lighter, shifts the centre of gravity, changes the controller’s low-voltage cut-off requirement, and demands a BMS where lead-acid needed none. Charger profiles, contactor ratings, fuse coordination and the vehicle’s range-versus-payload curve all change, and each is recalculated rather than assumed.

What battery and BMS specification does the book recommend?

Pack design is worked through for LFP at 48 V and 60 V nominal, with cell selection criteria covering cycle life at Indian ambient temperature, continuous and peak C-rate against the controller’s current limit, and enclosure ingress protection for monsoon and dust. BMS requirements cover cell balancing, over-current and over-temperature cut-off thresholds, contactor control, and the state-of-charge display the driver actually relies on.

Is the book useful for a workshop doing retrofits commercially?

Yes. A full chapter covers the commercial retrofit: kit approval by a notified test agency, workshop process sheets, torque and crimp specifications for HV joints, insulation-resistance and dielectric tests before handover, and the registration-endorsement paperwork. Costing worksheets cover kit cost, labour hours and warranty reserve so a workshop can price a retrofit with its real margin visible.

About E-Rickshaw Engineering

E-Rickshaw Engineering is part of the 3D-LABS Bikes & EV series — a focused e-book library for automotive engineers, EV designers, and electric mobility researchers. This title covers electric vehicle powertrain, battery technology, charging infrastructure, motor design, and sustainable mobility, with worked examples and industry-current best practices drawn from real electric mobility projects.

Written by practising 3D-LABS engineers and reviewed by senior specialists, E-Rickshaw Engineering is designed to move you from concept to competence quickly — not to be a comprehensive academic reference, but a working reference you actually use.

Who E-Rickshaw Engineering is for

E-Rickshaw Engineering is written for automotive engineers, EV designers, and electric mobility researchers. If you are:

• An early-career engineer wanting to accelerate your practical knowledge in electric mobility.
• An experienced practitioner looking for a compact reference on current practices.
• A student preparing for engineering exams, interviews, or your first professional role.
• A manager or team lead wanting to level-set your team on electric mobility fundamentals.

Then E-Rickshaw Engineering will earn its price back in the first project or exam you apply it to.

What is included in your download

• The complete PDF e-book — DRM-free, fully searchable, print-friendly formatting.
• Worked examples — real-world calculations, drawings, or case studies interspersed through the text.
• Reference charts and tables — quick-lookup material you will return to on the job.
• Further reading recommendations — curated pointers to codes, standards, and complementary resources.
• Free updates — when we revise the book, you get the updated PDF at no extra cost. We notify you by email.

How to get the most out of E-Rickshaw Engineering

1. Read the introduction and structure first — every book has a "how to use this book" section that maps chapters to the reader you are.
2. Work through the examples with pen and paper — passive reading is 10% retention; working the calculation yourself is 70%+.
3. Cross-reference with the 3D-LABS spreadsheet library — 686 Excel calculation tools that pair naturally with our e-books.
4. Apply the concepts to a real project immediately — the book will pay for itself the first time you avoid a design error.
5. Come back to the book after 6 months — with real project experience, you will read the same chapters differently.
