Why do lithium-ion batteries get used in electric vehicles? The principal reason why lithium-ion batteries get used in electric vehicles is that they are a safer option compared to their different alternatives. This is because battery manufacturers forever ensure that customers remain protected in the unlikely event of a system failure. Automakers, for example, install charging protections in electric cars to protect the batteries from repetitive rapid charging sessions in a short amount of time. Fuel cells go through a ‘discharge’ cycle while driving and a ‘charge’ cycle when the vehicle gets plugged in. The amount of current the battery can hold is affected by repeating the procedure over time. This reduces the range and time required to charge between trips. The majority of battery manufacturers offer a five- to eight-year guarantee. On the other hand, an electric vehicle battery lasts between 10 to 20 years before requiring a replacement. The connection between a battery and an electric motor in a car is relatively simple. The battery gets connected to one or more electric engines that drive the wheels. When you push the gas pedal, your car immediately sends power to the grid, which gradually depletes the battery’s energy. %% Continuous voltage ⚡ Another advantage of lithium-ion batteries is that they are competent in keeping a steady voltage. No matter how heavy the usage or load is, a lithium-ion battery will successfully retain the voltage fixed. This is because the voltage generated by every lithium-ion cell is approximately 3.6 volts which is pretty higher than its other substitutes. @@ Cost-effective As Lithium-Ion batteries have remained in existence for a long time, the cost of producing this battery has diminished significantly. Also, it is much more economical to implement a lithium-ion battery for a transportable device as these are promptly available and cost enormously less. High power density @@ High power density High power density is another principal benefit of lithium-ion battery technology. With electric devices such as mobile phones demanding to run longer between charges while still using more power, there is forever a requirement for batteries that hold a higher power density. %%%% Balancing methods can be used for lithium cells to: % Increase capacity Balancing allows the battery to achieve a higher state of charge (SOC). % Prolong cell life Balancing helps to maintain an equivalent state-of-charge (SOC) of every cell, to the degree possible given their different capacities. % Avoid safety problems Balancing ensures all cells in the pack have the same SOC, which can prevent safety problems associated with overcharging or over-discharging. % Balance voltage Balancing has the function of balancing the voltage of the lithium-ion battery pack.

#EVBatteryLife #RecurrentMotors "A comprehensive study by Recurrent Motors Inc., based on data from 15,000 electric vehicles (EVs) in the US, reveals surprisingly high durability of EV batteries, with most retaining 90% of their original range after 160,000 kilometers. While the cost of EV battery replacements can be significant, only 1.5% of cars had their batteries replaced, easing concerns over battery longevity. The findings, which highlight the potential for EV batteries to outlast their vehicles, are expected to encourage adoption of EVs, including used ones. This research, coupled with other studies and real-world data, points to a much longer lifespan for EV batteries than previously believed. ... EV batteries contain built-in protection mechanisms to prevent degradation. They are designed to be more resilient and operate within a certain temperature range for optimum performance. Heat management systems are incorporated in EVs to maintain the batteries within this range, preventing overheating and premature wear. Studies on older models like the Nissan LEAF and Tesla Model S have shown that EV batteries can outlast expectations. For example, Tesla confidently states that, on average, its batteries degrade by only 12% after approximately 320,000 kilometres of usage. This data from real-world observations demonstrates that EV batteries are more durable than previously thought, with many retaining around 90% of their capacity even after 320,000 kilometres. Best practices to protect battery health include avoiding excessive heat and managing the depth of discharge. It is recommended to keep a battery charge between 20% and 80% to extend its lifespan. Charging an EV battery to around 80-85% is considered optimal, while letting the battery go down to zero percent is not advised. The average loss in battery capacity for EVs is around 2.3% per year. Given this, the lifespan of an EV battery can be projected to last between 15 to 20 years or approximately between 160,000 and 320,000 kilometres. With the average lifespan of a car being roughly 12 years, it is evident that EV batteries have the potential to outlive the vehicles they power."

Ever wondered how the "engine" in electric vehicles works? It's a fascinating world under the hood! Let's break it down simply: The motor is the heart, the inverter is the brain, and the onboard charger is like the stomach! The motor is the powerhouse of an electric vehicle, akin to the heart in the human body. It's responsible for making the car move forward. However, unlike traditional cars that rely on petrol, the motor in an EV gets its power from electricity stored in a battery. The inverter, on the other hand, acts as the brain of the EV. It plays a critical role in the process by taking the direct current (DC) electricity from the battery and converting it into alternating current (AC) electricity that the motor can use to power the car. It's essentially a translator that helps the motor understand the language of electricity. The onboard charger serves as the stomach of the EV. It's responsible for taking AC electricity from an external source, like a charging station, and converting it back into DC electricity so that it can be stored in the battery. Think of it as digesting the electricity and preparing it for storage. Now, how are all of these components connected? It's like a captivating circle. The battery provides power to the inverter, which translates the power into a language the motor can understand. The motor then uses that power to move the car forward. And when the car isn't in motion, the onboard charger takes AC power from an external source and converts it back into DC power to recharge the battery, ready for the next adventure. Have you ever had the chance to peek beneath the bonnet of an EV and see these components in action? Share your experiences and thoughts on the incredible technology that makes EVs possible! Let's dive deeper into the electrifying world of electric vehicles. ⚡🚙💬
