Lithium-ion Battery for Electric Vehicles (EVs) | LOHUM

A lithium-ion battery is a type of rechargeable battery that uses lithium ions as the primary component of its electrochemistry. Lithium-ion batteries are used in electric vehicles to store energy that powers the vehicle’s electric motor. The rapid discharge rate of the lithium ion battery, combined with the electric motors of electric vehicles, provides almost instantaneous power delivery to the driver. This instant, electric power delivery is why EVs have superior torque and acceleration versus fossil fuel vehicles.

The typical range of an electric vehicle on a single charge varies depending on the vehicle’s battery capacity, driving conditions, the weight of the vehicle, temperature, and other factors. Most modern electric vehicles have an approximate range of between 150 Kilometers to 500 Kilometers on a single charge. Different battery chemistries carry differing characteristics such as longer range, longer battery life, or higher performance.

The time it takes to charge a lithium-ion battery in an electric car depends on the battery’s capacity, the charging station’s power output, and charger infrastructure, among other factors. Most electric cars can be charged to 80% capacity in around 30 minutes to 1 hour using a fast charger, while a full charge can take several hours.

A lithium-ion battery in an electric vehicle can endure between 1,000 and 2,000 charging cycles before its capacity begins to degrade. When it does begin to degrade, the battery loses some of its capacity and/or performance. When this happens, the EV battery reaches the end of its first life, and becomes eligible for reuse in second life applications. At LOHUM, EV battery can be repurposed to build EV charging station batteries that store solar power to charge EVs 24/7.

The lifespan of a lithium-ion battery in a 2-wheeler, 3-wheeler, or L5 EV vehicle depends on the battery’s quality, battery chemistry, usage, environmental and temperature contitions, and maintenance. Most lithium-ion batteries in electric vehicles have a total lifespan of between 8 to 10 years, which progressively diminishes in capacity or performance after the first 3 to 5 years with more charge cycles.

Lithium-ion batteries are generally safe for use in electric vehicles. However, they can pose a fire risk if they are physically damaged, overcharged, or exposed to high temperatures.

To maintain and extend the life of a lithium-ion battery in an EV, it is recommended to avoid exposing the battery to extreme temperatures, avoid frequently charging the battery to 100% capacity, and avoid discharging the battery to 0% capacity. Regular maintenance and software updates can also help extend the battery’s life. Maintenance, optimization, and battery health monitoring is widely the responsibility of Battery Management Systems (BMS) software and hardware, which also detects and reports battery problems.

Yes, you can replace the lithium-ion battery in your electric car. The cost of replacing the battery depends on the vehicle’s make and model, the battery’s capacity, and other factors. The cost of replacing an electric vehicle (EV) battery in India can vary depending on the make and model of the car, the capacity of the battery, and the location of the service center. 

While the cost of a Lithium-Ion Battery in India may range from Rs.15000-20000 per kwh. Most EV manufacturers provide a long warranty period on the battery and motor. So, if anything goes wrong during the warranty period, it will most likely be taken care of without being an unforeseen financial burden on the owner.

The performance of a lithium-ion battery in an electric vehicle can be affected by several factors, including temperature, charging habits, driving habits and style, and battery age.

There are several alternatives to lithium-ion batteries for electric vehicles, including nickel-metal hydride batteries, solid-state batteries, and hydrogen fuel cells. Biofuels are also an emerging contender that have seen innovation in 2-wheelers in India. However, lithium-ion batteries are currently the most widely used battery technology in electric vehicles due to their energy density, performance, cost, and reliability.

Lithium-ion batteries are used in electric vehicles because they are lightweight, have a high energy density, and can be recharged quickly. They are also more environmentally friendly than traditional lead-acid batteries, and can be recycled with 99.5% purity rates and around 95% recovery rates at LOHUM, making them significantly beneficial for a circular energy economy.

The production of lithium-ion batteries for EVs can have environmental impacts, including the depletion of natural resources, water pollution, and greenhouse gas emissions. However, the environmental impact of lithium-ion batteries is generally lower than that of traditional internal combustion engines, and is diminishing even further with advances at battery recycling technologies and proliferation of battery reuse.
