Our Well-Proven Process to Creating Custom Chargers

Building a custom battery charger that is fit-for-purpose takes a team of technical experts, including mechanical and electrical engineers. Accutronics’ teams work closely together and liaise with your device designers from the outset to ensure that charger requirements are met.

This clear communication, coupled with well-proven project management processes, ensures that custom solutions are delivered in a timely and cost effective manner. Take a look at the steps that go into the process below:

Understand

Design

Prototype

Validate

Tool

Build

Fixture

Qualify

Manufacture

UNDERSTAND

Project Launch

Understand & collate customer requirements.

Authoring of detailed technical specification & ongoing maintenance of project documentation.

DESIGN

Product Design

Detailed electrical & mechanical design of the product (i.e. the charger).
May include the purchase of initial design proving components & bench testing.

May include EMC pre-compliance testing (w/o report & w/o certification.

PROTOTYPE

Prototype Build

Fabrication of product (i.e. charger) parts using rapid prototype techniques.
Assembly & test of a small number of products (i.e. chargers) using limited fixturing, Quantity of product (i.e. charger) sent to customer for evaluation.

Quantity of product (i.e. chargers) retained by Accutronics for Design Validation (see below).

VALIDATE

Design Validation

Internal verification of the product (i.e. the charger).
Creation of test plan against the technical specification & subsequent internal laboratory testing of prototypes against plan.
Authoring of validation report.

Excludes external regulatory qualification which is done during Regulatory Qualification (see below).

TOOL

Tooling

Hard tooling of product (i.e. charger) components which may include injection moulded plastics, formed metal parts, PCBAs, light pipes, packaging, labels, PCBAs, membrane panels etc (this is neither an inclusive nor an exhaustive list).

Includes tool trials (where appropriate) & shipping of tools from Asia to UK (where appropriate).

BUILD

Pre-Series Build

Low volume build of non-qualified products (i.e. chargers) using production tooled components.

Majority sent to customer for approval, balance retained at Accutronics.

FIXTURE

Production Fixturing & Test

Design & build of production jigs & fixtures, test equipment & software.

This allows us to assemble & test the product in a volume production environment

QUALIFY

Regulatory Qualification

Purchase of components & assembly into product (i.e. chargers) for regulatory qualification testing.
Including creation of necessary paperwork. Shipment of product (i.e. chargers) to external test house for certification testing / reporting.

Test can include “IEC 62368-1, EMC, Ingress Protection Testing, Environmental Testing, RoHS, REACH, WEEE Validation (this is neither an inclusive nor an exhaustive list)

MANUFACTURE

New Product Introduction

Generation of production documentation, training of operators, build of a small NPI batch.

Later sent to customer as a homologation batch, retained at Accutronics or scrapped.
