Dakar recently introduced a fleet of electric Bus Rapid Transit (BRT) articulated buses (provided by Chinese CRRC). The delivery ceremony was held on November 28.
Dakar Mobilité, owned by Meridiam (70%) and the Fonds souverain d''Investissements stratégiques du Sénégal (FONSIS), has also recently announced that it has raised €135 million needed to deploy Dakar''s future electric BRT bus network. Proparco, EAIF, PIDG TA (Technical Assistance) and the European Union (EU) joined forces to secure the financing.
Dakar BRT project includes the operation and maintenance for 15 years of a new clean public transport network. Each bus has batteries with a capacity of 563.8 kWh. German company CarMedialab (part of INIT group) was selected to implement the charging management system.
Dakar Mobilité, overseeing bus procurement, maintenance, and BRT operations, just received 121 large-capacity electric vehicles. This move aims to reduce atmospheric emissions and the carbon footprint associated with transport in Dakar, avoiding an estimated 59,000 tonnes of CO2 emissions annually.
When it goes into service, the BRT system in Dakar will link the Petersen bus station at Dakar Plateau (in the city center) to the prefecture of Guédiawaye in the northern suburbs, thanks to a 121-bus fleet, powered 100% by electricity.
The BRT-system will become a major transportation option in the Dakar urban area,with an expected 300,000 passengers/day travelling between the suburbs and the city center. It will cover 18.3 km of Dakar, connecting 23 stations and 14 of the city''s most densely populated districts from north to south, via four lines (one "omnibus" line and three express or semi-express lines).
Electric vehicles (EVs) have become a ray of hope as the globe strives to address the issues of climate change and environmental sustainability. These electric-only vehicles mark a huge advancement in our search for greener, more environmentally friendly transportation options. The battery — a crucial element that determines the performance, safety, and efficiency of the EV — is at the core of these cars. The battery management system (BMS) is a sophisticated piece of technology that performs the complicated operation of managing this battery.
In addition to providing protection, the BMS regulates the environment of the battery by controlling the heating or cooling systems to keep the battery working within its ideal temperature range. Cell balancing is another crucial BMS function is that it ensure that each cell in a battery pack charges and discharges uniformly, enhancing the battery''s overall performance and durability. Modern rechargeable batteries'' dependability and safety are maintained by this system''s extensive monitoring, reporting, and protection functions.
The BMS functions as the battery pack''s "brain" in several ways. It makes judgments depending on the information it gathers, and these choices have an impact on the battery''s performance and longevity. Without a BMS, a battery might be overcharged or over-discharged, both of which have the potential to shorten its lifespan and cause battery failure.
The BMS is typically an embedded system and a specially designed electronic regulator that monitors and controls various battery parameters (e.g. temperature, voltage, and current) to keep the battery cells within a safe working range. Figure 1 depicts the overall structure of a BMS used in electric vehicles. The input, data processing, and output signals used in the BMS can be used to depict the data flow according to the architectural design.
The BMS serves a number of critical functions in the context of electric vehicles, including monitoring, protection, balancing, and thermal management. These functions are described in greater detail below.
The battery''s voltage, current, temperature, and SOC are all constantly monitored by the BMS. To evaluate the battery''s performance and condition, this information is essential. As an example, the SOC, which measures the battery''s remaining charge, has a direct impact on the EV''s driving range.
The BMS also keeps track of the battery''s SOH, which is a gauge of its general health. The SOH can give early warnings of prospective battery issues, enabling preemptive maintenance or enabling the replacement of faulty cells.
The BMS protects against probable problems that can hurt the battery and, consequently, the car. These protections include over-current (OC), over-voltage (OV), under-voltage (UV), over-temperature (OT), and under-temperature (UT) conditions. The BMS guarantees the battery''s longevity and safety by prohibiting it from running outside of its safe operating area (SOA).
Another crucial job of the BMS is battery balancing. It''s critical to maintain an even charge across all cells because an EV battery pack is made up of numerous individual cells. The BMS does this via active or passive balancing, enhancing the battery pack''s general effectiveness and durability.
The BMS is essential for controlling the temperature inside the battery pack. It assists in preventing overheating, a scenario that could result in shortened battery life or even thermal runaway, by monitoring the temperature and deploying cooling techniques as needed.
A dangerous situation known as a thermal runaway occurs when a spike in temperature causes further increases in temperature, which could result in an uncontrollable, destructive response. The BMS can stop thermal runaway and guarantee the battery''s safe operation by monitoring the temperature of the battery cells and acting as needed.
Battery management systems (BMS) are becoming increasingly complex as EV technology develops. It is expected that the future BMS will include cutting-edge capabilities like predictive analytics for greater performance optimization, increased safety protocols, and improved integration with other vehicle systems.
Using historical data and machine learning algorithms, predictive analytics make predictions about the future. This can entail projecting past performance to forecast the battery''s future state-of-charge (SOC) or overall health, in the context of a BMS. This would make it possible to manage the battery more proactively, thereby extending its lifespan and enhancing the efficiency of the EV.
Improved safety standards might include more sophisticated techniques for anticipating and avoiding potential battery issues. This might require more complex algorithms for spotting irregularities that might point to a possible issue as well as more comprehensive monitoring of the battery''s condition.
The BMS could communicate more directly with other EV systems, such as the motor controller or the onboard computer, to improve integration with other vehicle systems. This may make it possible for the car to operate more smoothly, which will enhance its effectiveness, performance, and user experience.
In summary, the battery management system (BMS) is a crucial part of electric vehicles that manages, safeguards, and monitors the battery. Understanding the nature and purpose of the BMS will help us better appreciate the intricate technological interplay that powers both current and future electric vehicles.
The BMS will certainly move forward and change as we continue to advance and stretch the limits of what is feasible with electric vehicles. We can make sure we are utilizing the potential of this technology to create safer, more effective, and more sustainable electric vehicles by keeping up with these improvements.
Understanding the function and significance of the BMS is essential whether you work for an electric vehicle manufacturer, create BMS systems, or are just a fan of the technology. The BMS will continue to be a key component of this innovative field of technology as we approach a future where electric cars are widely used.
