Electric vehicles are promoted by various governments through incentives offered by them and the reason behind this is that they emit lesser carbon emissions in comparison to vehicles that run on gasoline or fossil fuel. Electric vehicles run on batteries which are managed through a Battery management system, without BMS it is not safe to use these powerful Lithium-ion batteries as BMS not only improves the overall operational efficiency of the battery pack but ensures safe operations as well. The battery management system very much works in the same manner as the brain works in our body, the same is BMS for the battery pack in the electric vehicle. BMS is also getting advanced and there are BMS which have software linked to it, BMS link software suppliers are plenty in the market and these BMS link software suppliers are busy as demand for such software is pretty much on the rise.
A battery management system consists of electronic components and apart from these components, it has certain functions and features which help in the battery pack’s safety and operational requirements. BMS looks after the state of charge (SOC) and state of health (SOH) of battery packs. BMS controller suppliers are very much busy as the popularity of EVs is very much on the rise BMS controller suppliers are finding it difficult to meet the demand of the market. Key Components Of Battery Management System The battery management system does the following functions: 1. Voltage, current and temperature control and measurement. 2. Assessment of SOC and SOH. 3. Fault detection. 4. Cell balancing. 5. Data storage. There are mainly six components of the battery management system. 1. Battery cell monitor. 2. Cut-off FETs. 3. Monitoring of Temperature. 4. Cell voltage balance. 5. BMS algorithms. 6. Real-Time Clock ( RTC ) Significance And Application Of Each Component Battery Cell Monitor Its function is to monitor the voltage of the battery systems, capable of measuring high voltage and the overall cost is low for this component. Individual cell voltage is measured as it is the easiest way to determine the battery pack’s charge. Cut Off FETs FET driver connects and isolates the load and charger of the battery pack and it is done through voltage, current measurements, and real-time detection circuitry. MONITORING OF TEMPERATURE Through monitoring of temperature battery charging or discharging is assessed whether it is desirable or not. Temperature sensors monitor the energy storage system or cell grouping for compact portable applications. Cell Voltage Balance Cell voltage monitoring is crucial to determine the health of the battery pack, it ensures that the cells are in proper condition and long battery life is achieved. The best operating voltage ranges from 2.5V to 4.2V in a lithium-ion battery. BMS Algorithms A quick and effective decision is required to be taken based on information received and for this very purpose, a microcontroller for the battery management system is needed to collect, organize and assess the information from the sensing circuitry. Real-Time Clock It is very much the black box of the electric vehicle as it allows the user to know the behaviour of the battery pack along with the memory stage and time-stamping. Working On Battery Management System By tracking the status of each cell in the battery pack and determining the SOC ( state of charge ) and SOH ( state of health) it is estimated how much current is required for safe charge and discharge operations so that batteries are not harmed.

Introduction The popularity of electric vehicles is growing globally, and more and more people are opting for electric vehicles. Although EVs have grown in popularity they are still a long way to go before they can completely capture the automobile market. There is no doubt as far as the potential of an electric vehicle is concerned but there are certain challenges as well. The electric vehicle industry is consistently pushing towards widespread adoption and it has been able to achieve significant success as well despite prevailing challenges. In this blog we are going to discuss some of the factors that affect widespread adoption, they include both factors that push widespread adoption as well as those factors which are a hurdle in widespread adoption. Meaning Of Widespread Adoption Widespread adoption simply means electric cars becoming a major player in the automotive industry. Another way of the understanding meaning of widespread adoption is when electric vehicles become a prominent vehicle choice for consumers. Factors Affecting Adoption 1. Awareness: Public awareness regarding various benefits of Electric vehicles is one of the factors that truly affect the widespread adoption of an electric vehicle, it has been seen in countries where awareness is more adopted or the popularity of electric vehicles is more as well. 2. Range Of Vehicles: It is one of the important factors because long trips are a little tricky with electric vehicles. Electric-vehicle-battery suppliers have been asking manufacturers to make batteries which are more powerful as they are the ones who constantly face customers who keep demanding the same. 3. Speed Of Charging: If battery manufacturers can somehow make batteries which take less time in charging or fast chargers that are easily available with widespread charging infrastructure then it positively affects the adoption. Electric-vehicle-battery suppliers also need to make sure that their supply chain is maintained well. 4. Price Of Vehicle: Right now price of an electric vehicle is higher than fuel-driven or gasoline-driven vehicles, it is another factor that affects adoption. Affordable lithium-ion batteries and their availability through a network of affordable lithium-ion battery suppliers can be a solution to this. 5. Government Incentives: For full-scale adoption of electric vehicles government incentives are very much required without that it is not possible. And not just creating but extending those incentives is equally important. Battery manufacturers need incentives so that they can manufacture affordable lithium-ion batteries and a network of affordable lithium-ion battery suppliers can be created so that they are easily available to manufacturers as well as consumers. 6. Infrastructure: As electric vehicles run on batteries and charging infrastructure is extremely important, as electric vehicles can run up to 150 o 200 miles when fully charged so there is a need for electric outlets where they can be charged again. 7. Green Energy: Electric vehicles should be manufactured in such a way that they should increasingly benefit the earth. 8. Grid Development: New grids should be developed keeping the electric vehicle in mind and the goal should be clean and green energy production which would not only reduce the price of EVs but would further reduce carbon emission. 9. Gas Prices: Increase in gas prices as they have historically been a big factor as far as the adoption of electric vehicles is concerned. 10. Global Economy: It is one of the important factors that affect the adoption of EVs and there are many ways through which it can affect it. These are a few factors that affect the widespread adoption of electric vehicles and in future too they will decide how far this adoption goes. |
