People that don’t have LeafSpy have a difficult time comparing the bars on the 2018 Leaf battery temperature gauge to what charging speed they can expect. I developed the table below to help people trying to figure their potential charge speed with only the battery temperature gauge.
As you can see from the table, there is a pretty large temperature range for each bar and is a considerable amount of overlap with other bars. The information on battery temperature related to bars was extracted for the Electric Vehicle Wiki website, http://www.electricvehiclewiki.com/Battery#Battery_Temperature_Gauge. The information on battery charge rate related to battery temperature was extracted from the 22:05 mark of Lemon-Tea Leaf’s “40kWh Nissan Leaf 2018 - 376.1 miles (605.2 km) nonstop to Fully Charged Live Show in Silverstone” video;

and from a graph on the Clean Technica “2018 Leaf vs Long Journeys — Can It Take The Heat” article, https://cleantechnica.com/2018/07/16/2018-leaf-vs-long-journeys-can-it-take-the-heat/.
There was not any information for charging speeds below 54 F (12 C) or above 127 F (53 C) so that’s why there are question marks on the table. I know from personal experience that charge speeds can go down as low as 11 kW when the battery gets up to 11 bars so that’s data I added. Below is the battery charge rate versus battery temperature information extracted Lemon-Tea Leaf’s video.
The information above does not account for the performance of individual CHAdeMO chargers. If you want a more accurate information on your battery temperature than is available from the battery temperature gauge then you probably need to invest in LeafSpy. I hope Leaf owners and operators will find this information useful in managing their fast charging on long trips.
