Last week Frogparking read, with some concern, an article in the New Zealand Herald about on-street sensors exploding in the City of New Plymouth, New Zealand.
Frogparking can confirm that the sensors mentioned in the story are not associated with Frogparking.
Frogparking has had outdoor parking sensors, which utilise a different battery technology to that of the sensors mentioned in the story (Thionyl Chloride), installed at a number of locations in New Zealand, Australia, and the United States of America for over 11 years.
In that time, our sensors have never experienced any issues of the nature referred to in the article.
Frogparking is confident that our sensors present a very low risk of explosion.
Thionyl Chloride batteries, which power our sensors, possess a very stable battery chemistry. Additionally, our sensor’s enclosures are specifically designed for on-street use and feature a rugged design for the harshness which an on-street environment presents. The enclosures are designed to release pressure on the device, to protect all internal components, including the battery.
