At NexBlue, we try to develop our products not just to facilitate charging your vehicle as cheaply and as cleanly as possible, we also utilise the technology inside to inform customers when there might be something else wrong with their property.

When it goes wrong, electricity can be very dangerous, there is a reason that trained professionals are the only people who should get involved with it! Our charge points have a whole range of safety features in place to cut off the supply of energy should a fault be detected, however we can utilise the technology to also alert if there appears to be an issue with the property and not anything charging related

Voltage Alert

Although the UK Energy Networks attempts to regulate voltage at 230V, this fluctuates constantly throughout the day, hour, or even minute! However, voltage fluctuations are inevitable with loads all over the country constantly being switched on or off, in conjunction with supplies varying in output. Voltage readings can also fluctuate if there is an O-PEN fault at the property. The "safe" range for voltage is +/- 10% of the target voltage (230 V), meaning anything as low as 207 V or as high as 253 V is acceptable within the UK. 

The NexBlue products all measure the voltage on which they are connected to, and in most instances the value of voltage is accurate for the whole property, not just the specific device. The electrician responsible for the installation should check voltage readings when they complete any work to ensure values are within the safe range, however occasionally these can change over time.

If you receive an email from us saying that the voltage range has been detected to have strayed out of the safe range (207 V - 253 V), you should contact your Distribution Network Operator (DNO) to inform them. It is then their responsibly to reduce or increase the voltage for your property. As a means to aid their solution, request for an email address to send the email containing the voltage data to as supporting evidence for the issue.
