2011 and 2012 Nissan Leafs
The first add on improvement you can upgrade I would recommend is the Brusa NLG664 Nissan Leaf Charger. This acts as an add on to your existing 3.3.kw charger and increases its capacity to 22 kw! You can charge up your Nissan Leaf much fast and take advantage of 30 amp EVSE (Electric Vehicle Supply Equipment). This add on was launch back in 2013-14 and is sold via Metric Mind and maybe a few other vendors. According to the Metric Mind website, the price is over $5k so it is only for someone that is interested in getting the maximum charge performance out of the first-generation Nissan Leaf owners that are diehards. You can visit the Metric Mind website here.
The following quote is from The Metric Mind.
“With the NLG664 BRUSA has set an milestone in e-mobility. The on board fast charger NLG664 is now available with 45-65 Hz input frequency and enhanced single phase current capability of 30 A. This provides a great flexibility for the worldwide use of our NLG664 on-board-charger. Thanks to its performance upgrade the charger NLG664 can also be operated in countries with 60Hz mains frequency. The NLG664 is the world's first charger that allows the charging of a typical EV-battery in less than one hour from standard 3-phase AC grid and gives the additional option to charge with up to 7 kW from an appropriate single phase AC outlet.” And you can see a video of the product in an actual Nissan Leaf below.
For Nissan Leaf Owners that already have CHaDeMo high voltage DC Charging Capability
The next item that is a “must have” for any serious Nissan Leaf owner is to have the ability to “Fast Charge” in your own garage. Gone are the days when you wife comes home and leaves the Nissan Leaf battery depleted. Now with a eMotorworks DC fast charger set up you will have the ability to charge your Leaf from 0 to 80% capacity in just a fraction of the time. Only around 45 minutes.
Their website can be found here.
Text from their website states: “We are very happy to announce current availability of the product that many of you have been waiting for - a CHAdeMO-compatible charge controller. Now you can have an affordable charger that will charge your Nissan Leaf / Mitsubishi Mi-EV / any other car / motorcycle that uses CHAdeMO protocol - at up to 25kW from an AC source, up to 40kW from a DC source.”
