The Norwegian/Swedish-based company Tibber has launched a whole new generation of electric vehicle home chargers. They did this together with their hardware partner Easee. The charger is developed to help reduce the costs of charging electric cars at home.

The charger will do so with the help of so called “smart charging technology”, which means that the charger lowers charging speed for small periods at a time, when the power grid is in an immediate need to reduce consumption.

The charger is also equipped with technology that charges your electric car when the price of electric power is low. If you smart charge with Tibber, they guarantee that you get a 20% lower charging bill in Norway and a 50% lower bill in Sweden.

The charger can charge on both 1 and 3 phase and supports charging up to 22 kW, depending on which installation you choose. It has a Type 2 standard charging connector.

Tibber also launched 2 other products

The heart rate monitor for your home

This is a small box called Pulse, which is plugged into the new automatic flow meter (AMS) that all households in Norway and Sweeden is soon to have, giving you a constant overview of power consumption at home.

The purpose is to give the user an overview of which electric installations that uses power and how to reduce power consumption, in addition to informing you whether there is a power outage, or something goes wrong when you’re not at home.

Smart heat control with Tibber and Mill

The third product launched was a collaboration with the Norwegian electrical radiator manufacturer Mill, where the radiator uses Tibber’s technology for automatic heat control. Tibber already offers this technology for controlling air-condition-systems.

The product considers weather forecasts, thermal load, and the price of electric power to determine the effect you need for heating the house to avoid wasting power. It should be so easy to use that you only need to choose the desired temperature at home in the app, and Tibber will fix the rest.

A solar cell is made up of two layers of semiconductor metals, such as silicon. Photons in light are absorbed in the semiconductor and break electrons which, due to the semiconductor properties, can only move in one direction. We then have the basis of electrical power.

At the same time as solar cells are getting cheaper on the world marked, solar power is about to become the most important source of renewable energy. Availability and the low costs gives solar power great potential, but at the same time it’s vulnerable

Many of the places on earth that has the most sun hours and therefore become the best places for solar power, has big problems with pollution and smog. This makes the solar panels much less effective. This is proved by a new study, which was published in the scientific magazine Energy and Environmental Science.

The study which was carried out by a team of scientists from MIT in corporation with the University of Singapore, looked at 17 places where smog is a problem. One of these places is New Delhi in India. In The city which is one of the most polluted cities in the world, up to ten percent of the sun energy disappear due to smog and pollution.

When this much energy is wasted, the sun energy projects get less profitable. This makes it less likely that corporations’ will invest in this kind of technology, rather than coal powered plants to cover the demand for energy. This will increase the pollution and smog, and everything ends up in a bad circle which is difficult to break out from.

At the same time hydropower gets more expensive due to little rain.

In Norway Plus customers with solar power, who produces more power than they need are able to sell what they don’t need back to the power producer.

With this year’s extreme hot and sunny weather with very little rain, and more expensive power, a lot of the customers have benefited from this.

The problem has been that from the moment a solar producer does deliver more than 100 kilowatts to the power grid, they must pay a fee that is more expensive than the profit. Because of this a lot of the producers of solar power has toned down ore stopped the production this summer.

The Norwegian government has because of this changed the roles for these customers. From the beginning of 2019 these customers will no longer have to pay the expensive fees.
