Welcome to Kirby's Starterkit

A fully documented example project

I have over seven years of professional EMC experience on top of my experience with general electrical and electronics engineering, Including Power Electronics, both via formal education and personal projects, I believe the knowledge and skills built up during this time make me the perfect candidate for the role, One of my personal projects is to build an electric go-kart for my two children, this is being designed to be a frame welded from 20mm square box, and MDF sheet, the motors for it are recovered from “Hoverboards”, the control electronics will be bespoke with custom ESCs and BMS with the individual 21700 cells being built into packs.

Other personal projects I have worked on are a remote weather station powered by a small 3D printed wind turbine and feeding the data back to myself via the LoRa over the ThingsNetwork.

I hold both ARRIVAL and Jaguar Landover’s live hazardous voltage working certificates, this certifies that I can write test plans, and work on EV and BEV electrical vehicles DC bus under a permit to work system, I can also make a vehicle safe for others to work on and sign off the work they have undertaken.

I have a working knowledge of BS 7671 and have undergone the formal training to be certified to 17th edition.

While working for CASS I tested a large variety of appliances that were to be attached to both domestic and industrial supplies, both 230 V, and 415 V (wiring up and testing mains equipment with both inputs and outputs) as well as some sub-station and DNO equipment (circuit breakers and interrupters) with ratings well more than 400 A at 230 V (single-phase) or 11 kV AC (single-phase and three-phase).

I have an understanding of the EV charging system and have experience testing EVs with Level 2 and 3 chargers (normally via CCS type 2 connectors), I can interpret the command pilot signal to understand what the negotiated maximum current should be and can use this along with instrumentation to read the real-time status of the requested power level.

I have assembled and installed a small number of OpenEVSE for family and friends (final attachment to home distribution board undertaken by a Part P certified electrician).

A work-based solution I delivered was involved with the testing of Traction Inverters for EMC and functional testing, the motors they are designed to drive are 100 kW 400 V brushless motors, meaning at full load they can draw up to 400 A peak, this makes it hard to source the required power. The solution I implemented was to use two traction inverters and two traction motors and couple the motors mechanically together. One motor would be used as an electronic load, and the other would be running in regeneration mode, applying torque, and providing about 80% of the required electrical energy to the first, this meant that the current provided by the external PSUs could be vastly reduced.

I also implemented a standardisation on the Amphenol Industrial PL282 series of connectors for use in testing, this allows test setups to be quicker to set up and modify while ensuring safe isolation and containment for operators from HaV.

If I were successful in my application to take up this position, I believe I would bring my experience as an Engineer, as well as my ability to come up with unconventional solutions, or at least ask the questions that inspire others to come up with unorthodox solutions.

I have experience with solar PV from living on a narrowboat for seven years, my partner and I lived on a 57’ long Jonathan Wilson, our electrical requirements were supplied by a bank of lead-acid batteries, at 12 V, with charging supplied via photovoltaics and an alternator on the propulsion diesel engine.

I am actively working towards professional registration through the IET, with a view to becoming a chartered engineer.
