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?
"Torque" is an app that gets you access to the battery and motor data from the Battery Management System (BMS) via the On-Board Diagnostic port (OBD2). It's like a customisable version of "LeafSpy" but for other cars. Why would you be interested? If you need to ask then this probably isn't the post you're looking … Continue reading Ioniq Electric datafest- the “Torque” app
To answer this question, I tried out a Polar Ultracharger at the Holiday Inn Swindon, in the UK. The charger is quite close to J15 of the M4, and while the M4 is fairly well-served for charging, it's on the Electric Highway network which is, how shall I put it, a little creaky right now. … Continue reading How much can you top up an Ioniq in 10 minutes from a Polar Ultracharger?
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
Updated with EPA figures! TLDR - The Ioniq's class-leading combination of fast charging, very low drag and battery thermal management make it a very interesting alternative to the Leaf 30, or even the "new" Leaf 40 if you want to use the car for long trips. For lower speeds, day-to-day use and commuting the new … Continue reading The Ioniq electric: more like a “Model 3” class car than a Leaf
March 2018 Update - The 2018 Leaf 40 appears to have issues with repeated rapid charging, for example see Twitter posts tagged #AberdeenEVRace . In a contest between the Leaf 30 and the new 40, the Leaf 30 won! We have yet to see what response Nissan have to this. My guess is that it's … Continue reading Lets compare theoretical long journey times in the Ioniq, Leaf(s) and a diesel…(Version 2)
