Electric vehicles are the future. But they are the past as well - old electric vehicles are approaching the end of their useful lives. We don’t think that is necessary. At MUXSAN we are committed to upgrading and updating older electric vehicles to modern standards. Extending their range, retrofitting improved charging standards and maintaining cars that are mechanically excellent but showing their age otherwise.
Look around on our website to read more about our products. If you are interested in buying a range extending battery or one of our other products, we invite you to contact us or make an appointment through this website.
When buying one of our extender batteries or other products, you will need to bring your car to Delft, the Netherlands, for us to install it. Please consider if you are able to do that, before making an appointment. Installation takes one day for most products.

Nissan Leaf Battery Extender
Muxsan’s main product is the luggage space-mounted extender battery for the Nissan Leaf. We can install battery extenders in any Nissan Leaf (experimental for ZE1).
The extender battery is placed in the boot of your car, in a custom designed battery box. This battery box ensures your safety: it contains the battery and makes sure there is no way you can accidentally disconnect or break the extender battery. As such, you will be able to continue to use your trunk as you see fit: placing heavy things on top, even your dog having an accident will not harm the extender battery. (Fun fact: in the summer of 2018, we spilled an entire 1.5 liter bottle of soda on top of the prototype battery extender. It did not faze the batteries at all. Please do not try this at home)
As you can see in the images, the battery box takes up a bit of space in the boot of your car. For the 2011-2013 generation, the box will extend to just above the lip of the trunk. For the 2013-2017 generation, it will be a bit below that. The large extender battery adds approx. 160kg of weight to the back of your car. That is why we will modify the stock suspension for better rearward visibility and handling on bumpy roads. This is included in the price for a large extender battery.
With the extender battery, your range will roughly double. This will transform your Nissan Leaf from a city car to a true all-round usable car. We offer two sizes of battery extenders, either 8.8 kWh or 17.6 kWh. Please see the figure below, to check what your range would be with an extender in your Nissan Leaf. In most cases, your available range will be more than doubled with the large extender.

Benefits of getting a range extender
On top of the extended range, getting a battery extender will be very beneficial for your Nissan Leaf. The easiest way to explain the benefits, is to describe the extender battery as sharing the load for your car’s own battery. The extender battery takes some of the heat*, both in charging and in driving. This leads to a longer expected life span for your original Nissan Leaf battery and faster charging. With a MUXSAN range extender, you will be able to charge at full speed (approx 42-45kW) up to 60% charge, even in winter. This makes it possible to do longer trips with multiple fast charging sessions in a reasonable amount of time.
*Technically we are talking about the current. In real-life testing, the main battery had 70% lower peak current going in and out at 10 deg. C outside temperatures. As you can imagine, this leads to less heat being produced in the battery, thus mitigating the slower charging phenomena known as coldgate and rapidgate.

Nissan e-NV200 Battery Extender
The extender battery for the e-NV200 VAN and the Nissan e-NV200 EVALIA will improve the range of your car significantly. On top of that, you will benefit from faster charging and less battery degradation because of your choice to let Muxsan install a battery extender in your vehicle.
We offer a battery extender for your EVALIA of 26 kWh. We will install the battery extender in our workshop in Delft, in one day. The price for the 26 kWh Nissan Evalia battery extender is €8000 (excluding VAT), including installation and warranty.
The VAN has multiple extender battery size options. As such, we offer extender batteries up to 53 kWh. Please check the figure below for the price of a Nissan e-NV 200 battery extender. Prices are excluding VAT.
Extender | Price (ex. VAT) | Est. range | Remaining cargo capacity |
26 kWh | €8000 | 236 km | 555 kg |
35 kWh | €10,000 | 281 km | 475 kg |
44 kWh | €12,000 | 327 km | 395 kg |
53 kWh | €14,000 | 372 km | 315 kg |

Granny charger
We have developed an improved, faster charger for your home (and your grandmother’s home). You can use this Muxsan granny charger with any wall socket, and adjust the current as you go: better sockets can handle more current and charge your vehicle faster.
Another feature of this charger is that all the electronics are hidden in the connector, making it easy to store and use in all circumstances. There is no heavy ‘box’ hanging from your wall socket while you charge.
We are currently testing the prototype granny charger and will let you know as soon as it is ready to order. Please get in touch with us at info@muxsan.com with any questions about the Muxsan granny charger you may have.
3-phase charger
With the larger battery capacity, our customers have noticed that it takes a longer time to charge all those batteries. Nissan has only ever offered single phase charging with their electric vehicles, with 3.3 kW (approx. 20 km/h) and 6.6kW (40km/h) offerings. For a 24 kWh Leaf, that means your car will be fully charged during your working hours or overnight. With a range extender battery, charging times increase to unacceptable levels.
With three phase charging, provided you have access to three-phase charging stations, you can charge three times as quickly (11 or 22 kW), bringing back the charging time to just a couple of hours. You can be back to fully charged during a dinner date or a birthday party, giving you the full range of your extended battery for your drive home. Installing 3-phase charging does not interfere with the ability to fast-charge, in case you want to get going even faster.
Like the battery extender, the installation of 3-phase charging takes places in our Muxsan workshop in Delft, the Netherlands and will take approximately one day. We can combine the installation of your 3-phase charger with the installation of your extender battery on the same day and will give you a discount if you purchase both upgrades.
3-phase charging is available for the Nissan Leaf, Nissan e-NV200 VAN and Nissan e-NV200 EVALIA.
Prices for 3-phase charging are as follows:
How fast do you want to charge? | Price for 3-phase charging, including VAT, installation and warranty | Price for 3-phase charging, as additional purchase with a large extender battery |
11 kW | €2990 | €2490* |
22 kW | €4990 | €3990* |
*) This price does not include the price for the extender battery. Please refer to the page about the Muxsan extender battery for current pricing

Nissan Leaf tow hitch
Few electric cars have an approved tow hitch - even though in our opinion electric vehicles are ideal for towing heavy loads. With high torque at standstill to start moving confidently without risk of stalling the engine, smooth power delivery avoiding bumping around your valuable furniture during a house move and low noise, allowing you to hear if something is wrong, what is there not to love about towing loads behind your Leaf?
We offer installation of a Brink RMC removable tow hitch for €990. This can be combined on the same day of installation as your extender battery, battery swap or any other modification we offer.
Nissan has not homologated the Leaf for towing loads, so the tow hitch is technically strictly for use with bike racks and luggage boxes. We do not take any responsibility if you decide to tow, say, a car trailer with another Nissan Leaf on top. Do send us the pictures, though!
Nissan Leaf Battery Swaps/Upgrades
For some people, the additional range provided by the extender batteries is not enough. For those people, and for people who cannot afford the loss of boot space, we offer the option to swap your battery for any other Nissan Leaf battery. Yes, all Nissan Leaf batteries are essentially interchangeable. We regularly stock as-new batteries of all capacities. You can also bring your own battery and have us install it.
With the 40kWh batteries and larger, we highly recommend also installing a range-extender battery. These batteries are prone to overheating and will limit your ability to charge at DC fast chargers to 1-2 sessions per day - a phenomenon called rapidgate. With the range extender battery installed, your car can be fast charged and driven almost indefinitely before overheating.
The 40 and 62kWh batteries are also prone to more rapid degradation than other brands of batteries - something closely related to their overheating issues. This, too, can be partially mitigated with the installation of an extender battery.
It is possible to do downgrades, straight replacements or new installs as well (e.g. installing a bought battery into a Nissan Leaf with removed rental battery).
Prices including VAT and installation:
30 kWh | €6990 |
40 kWh | €8790 |
62 kWh | €13,490 |
Supply your own (24/30/40 kWh) | €1500 |
Supply your own (62kWh) | €2000 |
e-NV 200 Battery swap/upgrade
We offer the same service for your Nissan e-NV 200 or Evalia. Because of the added complexity of the coolant loop on the van battery, we charge an additional €500 per installation.
40 kWh | €9490 |
If you bring your own battery (any type) | €2000 |
