EV Battery Shifts: Impact on Performance and Customer Compensation
Recent adjustments to battery sourcing in electric vehicles from Škoda and Volkswagen have highlighted a critical,yet frequently enough opaque,aspect of EV ownership: the battery supply chain. While automakers readily advertise engine specifications in traditional combustion vehicles, the manufacturers of EV batteries remain largely undisclosed to consumers. This lack of transparency allows for adaptability in sourcing lithium cells,but can also lead to alterations in vehicle performance.
The Changing Landscape of EV Battery Suppliers
The ability to switch battery manufacturers without immediately raising concerns is a strategic advantage for automakers. It enables them to respond to supply chain dynamics, cost fluctuations, and technological advancements. Typically, these changes don’t significantly impact vehicle characteristics, and can even result in incremental improvements. However, the transition experienced by the Škoda elroq 85 and Volkswagen ID.4 models demonstrates that this isn’t always the case.
According to reports,both vehicles have transitioned from utilizing batteries manufactured by LG Energy Solution,a Korean company,to those supplied by CATL,a Chinese firm.While the usable battery capacity has remained consistent at 77 kWh, the maximum charging power has been reduced from 175 kW to 135 kW. This adjustment has resulted in a slight decrease in range – the Elroq 85’s range has been reduced from 581 kilometers to 573 kilometers, as per industry analysis.
Understanding the Impact on Charging Dynamics
Interestingly, the advertised 10-80% charging time of 28 minutes remains unchanged. This is due to a shift in the charging curve. The newer battery configuration charges slightly slower at lower states of charge, but maintains a higher charging rate for a more extended period, counteracting the faster power decline seen in the original battery design as it approached full capacity.
Though, this altered charging curve has practical implications for drivers. While a full charge might take the same amount of time, topping up the battery from, such as, 10% to 50% will now require a longer duration. This is a crucial consideration for drivers who rely on swift charging stops during longer journeys.As of 2024, approximately 35% of EV owners in the US cite charging time as a significant concern, according to a recent survey by J.D. Power.
Customer Response and Regional Differences
In Germany, Škoda and Volkswagen proactively addressed the change by offering a compensation of EUR 1000 to customers who had ordered their vehicles with the original 175 kW charging specifications. This demonstrates a commitment to customer satisfaction when performance expectations aren’t met.
However, this compensation wasn’t extended to customers in the Czech republic. Škoda Auto confirmed that all Elroq 85 orders in the Czech market were fulfilled with the originally specified 175 kW charging capability. Volkswagen echoed this sentiment, stating that customers were informed of the potential for a reduced charging rate (135 kW) at the point of sale if their vehicle utilized the CATL-supplied battery.
Future Outlook and Supplier Strategies
Volkswagen has indicated that the shift to CATL batteries was a “temporary change of production” and plans to reintroduce LG batteries in the summer. Škoda, though, appears to be committed to the CATL partnership, declining to comment on supplier matters. This divergence in strategy suggests differing long-term visions for battery sourcing within the Volkswagen Group. The global EV battery market is currently dominated by CATL, holding approximately 37% market share in 2023, followed by LG Energy Solution with around 15%, according to SNE Research. This dynamic likely influences the automakers’ decisions.
