• The project''s team is a good collaboration between National Labs and Industry. They team is working well together and does a good job meeting milestones. • The projects material development seems geared toward higher energy density material improvements, and it is not clear how those improvements relate to fast charging.
Faster charging may result in wider EV adoption and thereby support the CET of the transportation sector. However, the fast degradation of EV batteries comes with an enhanced need for more battery materials. Also, there is a need for more research on bidirectional charging with V2G, and battery ageing.
This report found most batteries still had had good capacity (more than 80%) even after propelling vehicles more than 200,000 km. Factors such as use patterns, advances in cell chemistry and optimised battery management were also found to influence battery ageing. What does this mean for the EV transition?
Often, driving a bit before fast charging is enough to warm up the battery. In addition, avoid fast charging an electric car at very low states or very high states of charge, since battery resistance will be higher. Recurrent emphasizes that almost all electric vehicles have software that will curtail fast charge speeds above 80% state of charge.
It is concluded that fast charging strategies may degrade the EV batteries the most, especially if fast charging is done at very high or low temperatures without the proper thermal management. Battery degradation is a non-linear process and the battery capacity of an EV is difficult to estimate.
Recurrent says on its website, “Like your phone, EV batteries degrade over time. Factors like temperature, age, charging habits, driving style and battery chemistry all impact battery performance. Recurrent provides transparency so that you can have confidence in your electric car and its battery.
There are several times when fast charging may have a big impact on your EV battery, it says. Avoid fast charging in extreme heat without preconditioning your battery. Preconditioning is when the car's thermal management system pre-cools the battery so that it can accept a higher charge rate without overheating.
