QUICK AND EASY DIAGNOSIS FOR EV CHARGEPOINT


PROBLEMS The growing popularity of electric vehicles (EVs) and hybrids puts even more emphasis on the ability of the power charging infrastructure to operate effectively and safely at all times.


To meet this need, a new easy-to-use specialist test and diagnostic tool has been introduced that is capable of carrying out comprehensive validation and fault finding on all types of AC electric vehicle charging and supply equipment (EVSE).


The hand held EV100 tester from Seaward carries out all of the tests to ensure that EVSE operates correctly and safely at the time of installation and as part of any ongoing periodic maintenance schedules, in accordance with IEC 61851.


As well as carrying out basic field tests, more detailed diagnostic data from the chargepoint is retained in the unit and can be transferred to a mobile Android app using NFC wireless communications. This comprehensive technical data can then be quickly sent to a specialist engineer or head office location for full remote fault diagnosis and records management purposes.


The lightweight and handheld EV100 simulates all of the commonly used charging cable ratings to quickly and easily verify the correct response from the EVSE.


An extensive set of tests and measurements are automatically carried out and displayed at the press of a button, including output voltage, maximum available charging current, earth loop impedance and RCD trip time. Insulation tests are also carried out on the EV charging cable to verify safety for users.


Importantly the new tester can confirm the presence of correct mains supply and earthing connections on single or three- phase systems without the need for additional equipment or the dismantling the charging point to access internal conductors.


For diagnostic testing, the dedicated EV100 tester also simulates a number of vehicle faults and measures the EVSE response, including disconnection time and the amplitude, frequency and duty cycle of the PWM signal.


The comprehensive simulation, test and diagnostic functions of the new EV100 means EVSE maintenance checks and fault finding can be undertaken quickly and cost effectively – helping to ensure that EV charging points remain operational and fit for purpose at all times.

WHAT I LEARNT THIS MONTH Liz Kentish


Struggling to reach an item on a high shelf at the local ironmongers, I eventually asked another (taller) customer if they could reach it for me. “Of course I can” and he did. “Is there anything else I can get for you?” he asked. I didn’t need anything else but thanked him for his assistance. All it took to get some help was to ask for it.


Similar situations occur at work, day in day out. People struggle with something but for whatever reason, they do not feel that they can ask their colleagues or their manager for help. It may be a British thing, asking for help is often seen as a weakness, or not being up to the job, when in reality there will be times that all of us need some help, advice or support.


Interestingly when you do ask, people are only too happy to provide it and will normally offer more than you require, just like my tall helper in the ironmongers.


We all like to be asked to help because it makes us feel valued that another person sees you as having the answer to their problem. Yet knowing that, we still find it difficult to ask for help ourselves.


The next time that you need help, instead of struggling or waiting for someone to give you a hand, just ask and you’ll be pleasantly surprised as to the outcome.
