ENGINEERING BRIEF

Good requirements make better decisions.

Jetray’s corporate website describes cell selection, BMS design, prototyping and custom pack services. Use this brief to discuss the scope and feasibility of your own project.

From requirements to review

Make the important interfaces explicit.

Explore lithium-ion battery packs by voltage, energy and integration needs. Start with the load profile. Build the specification around the real application.

Define the electrical window

Provide nominal voltage, maximum charging voltage, continuous load and measured peak current.

Make the integration measurable

Document the enclosure drawing, cable routing, connector pinout and communication requirements.

Agree the acceptance test

Use a signed specification covering capacity test conditions, protection limits and sample approval.

A practical project brief

What to share with the engineering team.

Electrical

Nominal system voltage, allowable input window, continuous current, peak current and peak duration.

Mechanical

Available envelope, fixing points, weight constraints, cable routing, connector and polarity.

Charging & communication

Charger model, charging opportunities, temperature sensing and required BMS or communication signals.

Project & documentation

Intended use, target markets, sample quantities, forecast volume, required test evidence and revision controls.

Project review stages

Keep the decisions and the documents together.

Use these review gates to organize a project discussion with the supplier. The agreed scope and deliverables are confirmed for the individual project.

StageInformation to alignDecision to record
Requirements briefOperating voltage window, continuous current and startup peaks; Ambient temperature, handling and available enclosure spaceThe equipment needs, mandatory limits and open questions.
Configuration reviewRecord the battery configuration, charge and discharge limits and the electrical interface to the host equipment.The proposed model or design scope, interface drawing and document revision.
Sample evaluationRepresentative equipment, operating cycle and acceptance procedure.Results, deviations and changes needed before the next stage.
Order preparationThe approved configuration, quantity, packaging and required shipment documents.The purchase specification, acceptance method and agreed commercial terms.
A useful conversation starts with a specification

Tell us what your equipment needs.

Share the load, dimensions and intended use. Ask for a current model specification and a project review.
