How to reduce the deterioration of a battery?

Strategies adopted include narrowing the SOC range, narrowing cut-off voltages and limiting charging/discharging currents. Panasonic described a lifetime estimation approach and then presented a deterioration suppressing method, by decreasing the charge cut-off voltage and increasing the discharge cut-off voltage .

How to reduce battery capacity loss?

The operating temperature of the battery is another efficient variable to reduce battery degradation; however, it highly influences the required cooling power, which directly accelerates the depletion rate of the battery. Thus, deploying further influencing variables on capacity loss is considered as a short-term upgrade of our work.

How is battery output current compared to battery capacity loss?

Battery output current over time during simulation. The battery capacity loss of the model (21) is also compared to the capacity loss data obtained from experimental data In order to verify the aging model, wherein both are subjected to identical operating conditions.

Can battery size be reduced?

Future work could focus on the extent to which battery size can be reduced based upon a better understanding of degradation, and the trade-off between reducing initial capital cost associated with a smaller battery system, and reduced degradation associated with an oversized system with SOC-based derating. 5.3.2. Temperature-based derating

What is a battery degradation curve?

Figures 15 and 16 show the battery degradation curve form the initial capacity of the battery to reaching the EoL over distance and time respectively. It can be seen from Fig. 15 that, before optimization, the vehicle covers distances of 160,000 km, whereas, in optimized mode, the vehicle covers a distance of nearly 200,000 km.

How to reduce lithium ion battery degradation?

The results indicated that it is crucial to avoid deep cycles over 60 % DoD, high temperatures exceeding <30 \ (^ {\circ }\) C, and high average SoC exceeding 60 % to ensure an maximal battery lifetime for EVs. Two fast charging strategies for Li-ion batteries to minimize degradation by reducing the lithium plating have been proposed in Ref. 19.
