The Rise of the Electric Car Factory Supplier
The rise of electric vehicles is changing the world’s supply chain. Procurement practices are shifting towards more sustainable options, while partnerships between automakers and battery manufacturers are on the rise.
After raw materials are mined (the upstream portion of the EV battery supply chain), they are sent to facilities for processing and refining, cathode and cell production, and assembly into modules and packs. This is the downstream portion of the supply chain.
Battery Modules
A battery module is a self-contained unit that contains a set of lithium-ion batteries. These cells are connected in series or parallel and housed in a metal frame that protects them from shocks and vibrations. The modules are then sold to automakers who place them in EVs.
The batteries in EVs are a critical component that weighs up to a quarter of the vehicle’s total mass. They also have a significant impact on the electric car’s range and acceleration. A modular battery electric car factory supplier system allows for increased battery capacity without increasing the overall size of an EV. This can increase the vehicle’s range, and it also makes EVs more affordable for a wider customer base.
Modular battery systems can be removed and replaced in a relatively simple process. The operator simply disconnects the electronic connections between the battery pack and the control unit, and then removes it from the car’s chassis. The battery pack can then be charged and installed in another electric vehicle.
Battery modules can be designed to include a battery heater, which can warm the battery before use in cold weather. This can mitigate the impact of low temperatures on a battery’s performance, and it can improve a vehicle’s range and efficiency. Additionally, localizing the EV battery supply chain can boost economic development by supporting mineral extraction and processing facilities and creating jobs.
Battery Packs
While most consumers understand what goes into a traditional gas-powered automobile engine, the components that make up an electric vehicle (EV) battery pack are less clear. This is because the EV manufacturing process uses different raw materials than traditional automobile production. In addition, EV batteries require specialized operating conditions to ensure they perform at their best.
To produce an EV battery, manufacturers first build a battery module from battery cells. These battery cells can be made from different metals and have varying physical shapes. Cells also have different chemistry, which determines their performance and specifications. Different chemistries can achieve a range of power and voltage options, but all cells have the same basic design: a stack of metal plates with an electrolyte that absorbs and stores energy.
Once battery modules are assembled, they are sent to automakers who place them in EVs for sale. However, many automakers are increasingly investing in their own EV battery factories to reduce reliance on overseas suppliers and ensure the integrity of supply chains.
Domestic EV battery manufacturing has the potential to improve traceability and ethical sourcing by reducing reliance on minerals from specific countries. This can help mitigate environmental and human rights impacts of mining operations as well as mitigate a number of other issues related to the production of EV batteries.
Battery Chargers
EV battery chargers are the key to helping people enjoy the benefits of clean mobility. Companies such as Blink Charging, Allego, and ChargePoint are focused on ensuring widespread availability of charging stations to support EV adoption. These companies are also committed to environmental sustainability. In addition to reducing vehicular pollution, they are working towards providing charging solutions that are safe and efficient.
The global market for electric car battery chargers is expected to grow at a rapid pace throughout the forecast period. This growth is attributed to favorable government policies and stringent emission rules. Growing vehicle electrification is another factor driving the demand for EV battery chargers. Moreover, growing concern over global warming and increasing investments in the automotive industry are projected to further propel market growth.
Various factors are anticipated to limit the market growth for electric car battery chargers, including adherence to stringent regulations and standards in different nations, intense competition, and fluctuating raw material prices. Additionally, lack of requisite charging infrastructure in underdeveloped and developing nations is estimated to restrain the growth of this market.
The US is a key driver for this technology, thanks to the popularity of Tesla cars. This has helped LG Energy Solution boost its sales, as it supplies batteries for EVs from automakers like Porsche and Lucid. It is also a stakeholder in Ultium Cells, which produces the cells used in the Cadillac Lyriq and GMC Hummer EV.
Battery Management Systems
BMS monitors the voltage and current of each individual battery cell in a multicell pack, ensuring that the batteries stay within their safe operating parameters. This prevents overheating or over-charging of the cells, thereby extending their lifespan and usable capacity.
It also ensures that the cells are not overdischarged. The battery cell voltage is constantly monitored and if the BMS detects that motorcycle supplier the cells are being overcharged or overdischarged, it will disconnect the battery from the charger or slow down the charging speed to prevent damage to the battery.
The BMS also monitors the temperature of each cell, managing the conditions by activating cooling or heating systems to maintain the desired operating temperatures. This extends the life of the cells, increases the usable capacity of the battery and reduces battery degradation.
The BMS also estimates the state of charge (SoC) of an EV’s battery to indicate its range to the driver. The more accurate this estimation is, the less range anxiety drivers experience when driving EVs. The SoC estimation is performed using various methods, each with their own trade-offs. Finally, the BMS monitors internal battery faults, such as metal lithium plating, solid electrolyte interphase (SEI), dendrite formation and decomposition, and thermal runaway, to protect the vehicle occupants. It can also detect any cell that is prone to a fire and alert the vehicle manufacturer, preventing costly public relations disasters such as the GM Bolt recall.
