Simple - it's not really a 50kW charger. Eh? Today's chargers such as Polar's Ultracharger, and most other rapid chargers, in the UK at least, will deliver, at most, 125 Amps*. Whether that translates to 50kW, depends on the voltage of your car's battery. (Power = Current x Voltage). Take into account some loss along … Continue reading Why am I not getting a 50kW charge from a “50kW” rapid charger?
April '19- Our two Ioniq electrics have been performing just like any other "normal" cars over the winter - hence my lack of blog posts. But that's unfair to the Hyundais - to be able to rely on affordable electric cars for everyday use, as well as longer trips in 2019 really is newsworthy! One … Continue reading Business as usual
Welcome to my most popular blog post. Looks like battery health/life is a big concern amongst my readers! When I bought my Nissan Leaf at 3 years old, it had 88% battery "health" as reported by the car. Battery degradation is inevitable with electric vehicles, it's just a question of how much. If you're interested … Continue reading Ioniq electric battery health at 3 years and 36,000 miles – very healthy, 100% health and 28.6kWh net capacity *Updated*
*excludes Tesla superchargers My EV adventure, day 1 rapid charging! When I got my first EV in 2016, a used Leaf, I wanted to rapid charge it straight away. Way back then the Electric Highway was free! Plugging in an EV at Membury west was awesome, I felt the future was literally here. As I … Continue reading The state of public rapid charging in late 2018 in the UK*
I think there's a strong case for a family pure-electric car with a modest battery, good efficiency and fast charging. As public charging points become more plentiful and powerful, the modest battery EV gets more useful. A side-effect is that the embodied energy of such a car is less than one with a larger battery … Continue reading What spec does a long-distance family electric car really need in the UK?
...it needs to be collected from Aberdeen, 530 miles away. Before this trip I hadn't attempted a really long journey in an EV. (In case you're not aware, this car is all-electric, no "engine", it doesn't take diesel or petrol). However my experience of the Ioniq was that the car could do it, and I … Continue reading Picking up another Ioniq electric! But wait, there’s a catch…
I measured a charger efficiency of 86% in the Leaf and 95% in the Ioniq. Electric cars display an efficiency figure which can range from 3 to 7 miles per kWh in my experience. This is the efficiency that the car measures, from the battery to the road. There are other losses in the system, … Continue reading Efficiency and charging losses, Leaf vs Ioniq
