Some 22 kWh are usable, giving the car an official EPA range of 84 miles (140 km) when the car is new.Īll batteries degrade with time and use. Not all that capacity is used to propel the car. The 2015 Nissan Leaf was built with a 24 kWh traction battery. That’s as much as some Americans drive per year. In two years we’ve put about 14,000 miles (23,000 km) on the car. Thus, we drive less per year than the average North American family. My wife Nancy is retired and I work at home. Our car did not sit idle long on the dealer’s lot before it was shipped to us. Our Leaf was manufactured in September 2014 and we took delivery in October 2014. The amount of time EVs set on a dealer’s lot unused can affect later degradation of the traction battery. The event was a good time to take stock of how much the Leaf’s traction battery has degraded during that time. In addition to this, when left open, the battery pack is no longer water tight creating another risk of safety or damage.Ĭustom made from high quality anodised aluminium and engineering grade plastics, this Delete Cap securely fits over the PTC Power Outlet, completing the required detection circuit while sealing and protecting the connector to allow safe operation.We recently passed the two-year mark on our 2015 Nissan Leaf, a battery electric vehicle (EV). In this case, the connector has a safety detection circuit that will prevent the car being driven. In addition to the communications problems solved by our battery translators, the additional connector creates a problem when fitting a later packs into the original 2011-2012 Leaf as there will be nothing connected to this connector on the replacement battery. The ZE0 Leaf instead supplied power to the PTC heater from the junction box in the engine bay. This was not found on the original battery packs from the 20 (ZE0). Using the entire battery pack from another vehicle ensures that the LBC is a perfect match for the cells being used so it can function as originally intended.Ī major difference found on the 2013 or newer (AZE0 & ZE1) model Nissan Leaf high voltage battery packs was the addition of a connector to supply power to the the PTC heater. The battery translator module sits between the donor battery and recipient Leaf keeping all systems happy. The solution is EVs Enhanced’s HV Battery Translator, a battery to car translator that can be easily installed to effortlessly and elegantly resolve communications problems between an earlier car and a later-type battery. This process was also time consuming, hazardous and far from elegant. However, using an earlier LBC with higher capacity cells than it was designed for, creates significant problems with the estimation of battery capacity, state of charge and range. Previously the only way to achieve these conversions was opening the factory sealed battery pack and swapping various components such as the LBC. ![]() This is done by transferring the complete battery pack along with its correct lithium battery controller (LBC) which is fitted inside it. Our HV Battery Translator allows the ability to swap later model higher capacity (longer range) battery packs into earlier cars. ![]() While our existing battery pairing tool already allows battery swaps to be performed efficiently and safely between like-to-like models, its use is limited to swapping battery packs within the same generation of Leaf battery packs, of which there are several variants (there are currently 7 which we are aware of).
