As electric vehicles (EVs) gain popularity, Nissan Leaf owners may find themselves exploring ways to enhance their vehicle’s range, especially in challenging weather conditions.
One intriguing solution gaining attention is the DIY range extender for the Nissan Leaf.
In this article, we will delve into the essentials of a Nissan Leaf DIY range extender, covering key considerations, technical aspects, and the potential impact on your electric driving experience.
Understanding the Need
The Nissan Leaf, a popular electric vehicle known for its eco-friendly credentials, may face limitations in range during extreme weather conditions. Seeking a solution for a reduced range in cold weather, some Leaf owners have explored the concept of a DIY range extender.
This extension aims to provide an extra boost to the vehicle’s range, particularly during cold winter days.
Muxsan’s Contribution
A notable player in the realm of Nissan Leaf range extenders is Muxsan, a company offering off-the-rack battery range extenders. These extenders can potentially provide additional kilometers to the Leaf’s range, offering a solution for those looking to take the DIY route.
Integration with Car’s UI
A critical question for any range extender is whether the car’s user interface (UI) can understand the additional range. According to reports, there is a small printed circuit board (PCB) tucked away under the glove box that communicates with the Controller Area Network (CAN) bus.
This ensures that the vehicle’s UI recognizes and adapts to the extended range seamlessly.

Connection and Electrical Work
The DIY range extender involves more than a simple plug-and-play setup. Users interested in this modification should be aware that it requires connecting a set of cells in parallel to the main pack on the 400V bus.
The extender pack incorporates specialized circuitry to connect in parallel only when the main pack is turned on, ensuring that the paralleling process happens only when the voltages are within tolerances.
This intricate electrical work requires attention to detail and a good understanding of the Leaf’s electrical system.
Visibility and Charging Speed
One of the advantages touted by DIY range extender owners is the increased charging speed. The additional range allows for faster charging up to 90-95% state of charge, offering more flexibility on long trips.
This adds convenience of being able to charge with 40-45 kW consistently within this extended range.

Considerations for DIY Enthusiasts
While the concept of a DIY range extender may sound appealing to Nissan Leaf owners, it’s essential to consider a few key factors before embarking on such a project.
The extender is not a one-size-fits-all solution, residing in the trunk and integrating into the high-voltage system. Potential DIYers must choose between 11-33 kWh of extra battery, and the extender’s weight necessitates modifications to the rear suspension.
Cost and Effectiveness
One of the significant factors influencing the decision to pursue a DIY range extender is the cost. The concept of using a portable battery like a 1 kWh Jackery battery to trickle charge the main battery might be tempting, but it may not be cost-effective.
Estimates suggest gaining only 5-10 km of range for approximately $2000, making it a potentially expensive venture for a relatively modest increase.
Conclusion
As Nissan Leaf owners explore ways to enhance their EV experience, the DIY range extender emerges as a fascinating option.
Muxsan’s offerings and user experiences shed light on the potential benefits and challenges associated with this modification. From understanding the integration with the car’s UI to the intricate electrical work involved, aspiring DIYers should approach this project with careful consideration.
While the DIY route may not be for everyone, it certainly adds a layer of customization and innovation to the world of electric vehicles, offering a glimpse into the possibilities of extending the reach of eco-friendly commuting
