How much replace batteries of an electric car ?

 How much does an electric car battery cost?

Without a doubt, the battery is one of the most expensive components of an electric car, not to say outright that it is clearly the most expensive. For this reason, surely you have ever wondered: how much does the battery of an electric car cost? That is something that here, finally, you will be able to discover.

According to what I have been able to investigate, with not too up-to-date data prepared by Bloomberg in 2015, the battery of an electric car accounted for 57% of its total cost . And, according to experts, in 2025 it should be only 20%, which would mean a significant reduction in the total price of battery-powered vehicles. But the interesting thing is to discover the price today.

After making a content on how to correctly charge the battery of an electric car , in which we contacted all the manufacturers that have electric models for sale in Spain, we took the opportunity to ask them other questions. One of them was precisely this: 

How much could a replacement battery cost if the original one dies?

Some brands told us that this is information that they prefer not to disclose, others that it is information that needs to be confirmed, and similar responses. A strategy that can be understood or not, but that must be respected: the electric car is mine and I will inform you of what I think is appropriate...

Several manufacturers tell us the obvious, although perhaps it is not bad to remember it: "if the battery runs out during the warranty period, the customer would not have to pay anything".

But there have been brands that have gotten wet. This is the case of Honda , which confirms that " a new replacement battery costs 20,499.07 euros ". 

And Porsche is also transparent in this regard and gives us the exact prices (without VAT): 39,958.18 euros for the 93 kWh Taycan Performance Plus , which is 33,610.07 euros if it is an exchange. In the case of the 79 kWh Performance version, the price is 33,648.98 euros and 28,303.73 euros for an exchange.

Also Jaguar , which notes the following: "It depends on the model. Complete batteries are only replaced in certain cases, such as when there is impact damage. Usually components and battery cells can be replaced independently. A Jaguar I-Pace battery can cost 37,000 euros + VAT ".  

For their part, BMW, the entire Volkswagen Group and Renault tell us that it is not necessary to change the entire battery. And, if a part is defective, only that part is replaced. This includes battery modules.

Ford tells us the following: "we expect that the prices of the batteries at the moment in which they need to be replaced will have suffered a significant cost reduction compared to the current moment, but right now we cannot quantify it".

What percentage of the total price of the car does the battery represent? 

In addition, we took advantage of the occasion and asked them to answer this other question: What percentage of the total price of the car does the battery represent? 

In this case, as in the previous one, some manufacturers do not provide this information. Others, such as Nissan say that "given the wide variety of prices and incentives for different versions of a model equipped with the same battery, it is impossible to determine this percentage."   

And Mercedes tells us something similar: "it depends on the vehicle, the battery capacity, the range, since there are vehicles with 2 batteries. We cannot establish a weight on the price."

MG does clarify something else, although what it tells us is also evident: "it depends on the PVP of the vehicle and the capacity of the battery in kWh, as well as the materials used in its manufacture." And Jaguar adds: "the price of replacement batteries is not the factory price for a new car."

But others do give us concrete figures. Without a doubt, Porsche has once again been the clearest manufacturer regarding the percentage of the total price of the car that the battery represents : "It depends on the model: between 53% (Taycan model, with 93 kWh battery) and 25% (Taycan Turbo S model)."

Others tell us about future plans: "one of the Renault Group's objectives is to achieve a cost of less than 75 euros per kWh from 2024". That means that a 50 kWh battery would cost less than 4,000 euros . 

Without a doubt, it contrasts with the current cost per kWh that Toyota has given us: "it can reach 250 euros/kWh" . This, according to the previous example, would mean that a battery with a capacity of 50 kWh would cost 12,500 euros. 

It must be taken into account that Toyota works with very low costs, because they have been investing in R&D for 25 years in everything related to battery and electric propulsion, thanks to their hybrids.
