All the Things That Drain Your EV Battery

Heating and cooling power consumption could range from a few hundred watts when the ambient temperature is close to optimal, 1-2 kW when the environment is very hot or cold, or even up to 5+ kW if the vehicle is starting off very cold and the battery needs to be warmed up by a resistive heater.”.

Can Super-Fast Battery Charging Fix the Electric Car?

If the goal is to charge up your electrical vehicle in, say, five minutes, that extra current meeting resistance means temperature-related problems inside the battery and out.“I question the wisdom of why we need to have 500-mile range in an electric car and also want fast charging in five minutes,” he says.

Oceans Are 'Spiking a Fever' With Record Heat Waves

The number of heat waves affecting the planet’s oceans has increased sharply, scientists have revealed, killing swathes of sea life like “wildfires that take out huge areas of forest.” The damage caused in these hotspots is also harmful for humanity, which relies on the oceans for oxygen, food, storm protection and the removal of climate-warming carbon dioxide the atmosphere, they say.

The View From the Control Room: How InSight Landed on Mars

As the final hours ticked by before InSight breached Mars’s atmosphere and headed to the surface, there was not much to do except wait, and worry.Engineers had sent the landing sequence commands to the spacecraft days ago, where they now sat onboard like little bombs, waiting for the proper time to execute themselves.

Burning wood - not as cosy as it seems

Burning wood - not as cosy as it seems

Smoke from home fires in winter can be smelt across our towns, causing irritation and annoyance to some, reducing visibility, and frequently causing air quality to exceed the National Environmental Standard. Although we don’t monitor smog directly, the levels of smoke are indicated by networks of air quality monitors operated by regional councils.
