Batteries are literally the soul of an EV, and correctly maintaining them would keep the EV's cost of ownership low.
Prolonging the life of a car'sbattery helps to reduce the environmental effect of these vehicles by reducing the number of automobiles that are retired and sent through a yet-to-materialize recycling procedure. On the other end of the production cycle, it may lessen the need for more resource-intensive electricity to be generated in the first place.Simply taking care of a few things will extend the life of your battery.
Simply follow the steps below to maintain the health of your EV battery:
Reduce the exposure to high temperatures during storage and use. When possible, park your EV in the shade or plug it in so that the battery's heat management system can operate on grid
power. High temperatures can deteriorate the components that bind the carbon or metal oxide materials to the electrodes, melt the separator, dissolve the cathode metals, dissolve the SEI layer, cause oxygen loss from the cathode's metal-oxide, and/or decompose the electrolyte.
Reduce your exposure to cold temperatures—Once again, the hazard is largely unplugged parking in very cold temps. If you can plug in, the battery's thermal management system will keep it comfortable. Even when unplugged, some EVs run the thermal management system until capacity drops to 15%, at which point things get ugly. Low temperature also slows the pace at which ions diffuse through the separator.

Reduce the amount of time spent at full charge—Try to resist the desire to plug in all night every night. If your daily travels take 30% of the battery, using a middle 30% (between 70% and 40%) is healthier for the battery than continuously using the top 30%. Smart chargers will eventually interact with your calendar, anticipating daily driving needs and tailoring charging accordingly.
High state of charge can corrode the cathode's aluminium current collector, degrade the binder material, dissolve the SEI layer, cause gases to develop, increase internal mechanical stress, and decompose the electrolyte.
Reduce the amount of time spent at 0% charge—Battery management systems often turn off an EV before it reaches 0% charge. The greater risk is leaving a vehicle unplugged for so long that it self-discharges to zero and remains there for an extended period of time. Low State of Charge can corrode the anode's copper current collector and dissolve transition metals.

- Avoid use of fast chargers whenever possible:
Automakers are hesitant of advising against high-voltage DC charging because they know it's one of the keys to mainstream EV adoption. And it's certainly adequate for recharging for infrequent lengthy trips—or when a last-minute appointment depletes your strategic 70-percent overnight charge. Make it a point not to make it a habit. High Charging Current slows ion diffusion and amplifies volume changes and mechanical strains caused by charging.
- Avoid discharging faster than necessary:
Its pretty difficult to resist those Ludicrous Tesla launches, and they're pretty innocuous when enjoyed on occasion when demoing your car to a prospective EV convert. Just keep in mind that each one hastens the eventual deterioration of your vehicle's battery by a certain percentage. High Discharging Current causes Amplification of volume changes and mechanical strains during discharge.
Summing up, Following are the things to be followed in order to maximize the health of the battery of electric vehicles.
- Store the battery in a cool area.
- Use a battery that is no more than 6-7 months old from the date of purchase.
- Use the battery frequently and don't store it for an extended period of time.
- Use a partial charge discharge cycle to boost battery backup and extend battery life.
- Avoid overcharging the EV.
- Don't keep your battery for an extended period of time; instead, use it on a regular basis.

- Avoid charging the battery until it reaches 100% capacity (if possible)
- If the charging is low, avoid hasty driving.
- Avoid using the EV immediately after fully charging it (if possible)
- Avoid exposing the battery to high temperatures.
- Monitor the self-discharge an ideal battery will lose 5% of its capacity in 24 hours (if charged completely). If this is not the result of your observation after that 3 percent per week, your battery is considerably older.
