Second-life battery storage technologies are struggling to be a cost-competitive technology against first-life Li-ion battery energy storage systems (BESS). In their report on the topic, "Second-life Electric Vehicle Batteries 2025-2035: Markets, Forecasts, Players, and Technologies", IDTechEx explores various means for repurposers to generate revenue within the sector including renting systems and incentivizing automotive OEMs to share revenues.

IDTechEx reports positive growth of Li-ion batteries to be expected over the coming years, largely due to policy, technological improvements, and demand in major sectors such as the EV market and stationary energy storage.

Air cooling dominated the battery cooling market a few years ago but was overtaken by active cooling (using indirect liquid cooling methods) due to its ability to keep the cells at a more optimal temperature range, enabling greater battery longevity and faster charging. According to IDTechEx, this method is expected to be just as popular over the next decade, with trends predicted to be similar except for a small increase in immersion for niche applications.

Copper has been used in cars for as long as vehicles have had electrically powered features. Its main use today is as the vehicle's central nervous system, connecting a network of sensors, actuators, displays, and more to the vehicle's ECU brains. As cars evolve and utilize more electronic components, the demand for wiring will inevitably increase.

A power module in DC fast chargers is a critical component that converts AC grid power into high-voltage DC power to charge EV batteries efficiently. It integrates rectifiers, inverters, and control systems to ensure precise power delivery while optimizing energy efficiency and minimizing heat loss. Power modules are essential for achieving rapid charging speeds and supporting high-power applications, meeting the demands of growing EV adoption.

Construction vehicles running on diesel can be a creator of constant costs and air pollution, with continuous negative impacts on the environment and communities. The goal for electric construction vehicles is to achieve maximum productivity, reliability, and efficiency, while keeping costs minimized. Finding the right battery chemistry for electric construction machines is, therefore, a necessary consideration so that costs can be low enough to ensure the total cost of ownership over the vehicle's lifetime is cheaper than diesel alternatives.

Historically, heavy-duty trucks have proven difficult to electrify, with the average annual mileage of a truck approximately ten times that of a passenger vehicle, regularly driving hundreds of km a day. 2024 has seen further growth in the global electric truck market, with progressive emissions reductions mandated by governments projected to propel further uptake.

While the fully battery electric vehicle (BEV) has struggled in several key markets, its plug-in hybrid alternative (PHEV) has been experiencing a stellar year. On the surface, PHEVs may appear to be an ideal compromise: zero emissions travel but without the same extent of reliance on expensive Li-ion batteries and backup ICE power to quell range anxiety. So, have BEVs had their moment in the sun, and is the future hybrid?

IDTechEx forecasts the second-life EV battery market to grow to US$4.2B in value by 2035, given the increasing availability of retired EV batteries over the coming decade. Li-ion batteries in electric vehicles may be used for 6-15 years, depending on the application and their degradation over time. Once these batteries reach a capacity, or State-of-Health (SOH), that is too low to facilitate the driving range requirements of the EV, these are retired. These batteries could be recycled to reclaim critical and valuable raw materials, which could be reintroduced into new EV battery manufacturing.
