The first mission of a repair center is to repair the failed battery so that it can be placed back in the vehicle, which is the most cost-effective and sustainable way of dealing with failed batteries.

If the battery cannot be repaired for continued use in vehicles, there are still options to keep it away from disposal. The repair center will either send it to a partner company for a second life in non-automotive applications or to a recycling company where the raw materials are reclaimed for manufacturing new EV batteries.

The battery reconditioning process includes three phases. The battery is first tested and diagnosed, then repaired or certain parts are replaced by a team of high-voltage specialists. If repair for the electric vehicle is not possible, the battery or module is sent to a partner for remanufacturing or recycling. The repaired battery will then find its way back to the electric vehicle.

Battery maintenance is necessary to extend the service life of an EV’s battery pack. EV batteries require next-to-no maintenance throughout their service life, but drivers can do a few things to extend the battery’s life, such as avoiding extreme temperatures, which can degrade the battery, and not relying on fast chargers all the time. Automakers factor this into the development of their EVs, fitting them with the necessary auxiliary cooling and heating systems to help keep the temperature of the battery at acceptable levels.

In conclusion, extending the life of lithium-ion batteries saves costs for the manufacturer and the importer of electric vehicles, and is good news for the environment, which helps many European companies meet their sustainability goals. Battery repair centers can have a supporting function for specialized battery repair, and it makes sense that car manufacturers themselves will also play a major role in the extension of battery life.

How to Recondition Old EV Batteries to Extend Their Lifespan

Do You Save Money With A Hybrid Car?

Electric vehicles (EVs) have become an increasingly popular mode of transport due to their positive impact on the environment. EV batteries power the vehicle directly and use a pack consisting of 2,000 plus individual lithium-ion cells. EV batteries are more reliable and have a much longer lifespan compared to the heavy lead-acid batteries in conventional combustion engine cars. However, like all batteries, they will eventually lose their ability to hold a charge over time. So, can EV batteries be fixed or reconditioned?

When an EV battery loses its capacity to power a vehicle over distance, its ‘second life’ revs into action. The battery still has usable life in it and can be used as a static battery energy storage system. The residual life in the viable battery can help people save on bills and increase their use of clean energy.

If the battery’s performance drops to 70% or less, it can be reconditioned to restore its capacity to hold a charge. This process is known as EV battery reconditioning or refurbishment. EV battery reconditioning is a cost-effective way to extend the lifespan of your battery and save money in the long run.

To recondition an EV battery, first, it must be tested to determine the cells that are damaged and need replacing. Once the damaged cells are replaced, the battery must be reassembled and charged fully. Afterward, it is discharged until it is nearly dead, then charged again. This process must be repeated several times to ensure that the battery can hold its charge effectively.

EV battery maintenance and repair is essential to increase the lifespan of the battery. A battery management system (BMS) preserves battery efficiency and life. BMS allows the cells to be gently topped up, preventing the battery from overcharging or discharging. It is essential to keep the battery charged and discharged regularly. If the battery is not used regularly, it can lead to its degradation.

In conclusion, EV battery reconditioning is an effective way to extend the lifespan of your battery and save money in the long run. It is essential to maintain and repair the battery regularly, keeping the battery charged and discharged, and ensuring that it is topped up gently.
