Why is a Bidirectional DC-DC Converter Used in Electric Vehicles?

Electric vehicles are slowly taking over transportation since they result in cheap usage costs. Likewise, some people are curious to know how they perform with lightweight components compared to non-electric vehicles. The science behind it is that the current flows in the right direction at the correct rate. Not all components need the same current rate, and a DC-DC converter is installed inside EVs. A bidirectional DC DC converter supplier knows why this device is essential. The features inside it make an EV perform at the best level. You will know all the reasons why they are used in EVs below.

Stable Connection Between Battery and AC-DC Inverter

The first thing it creates for an EV is a stable connection. A bidirectional DC-DC converter brings stability between the battery and the AC-DC inverter. An EV requires an uninterrupted flow of current in both ways, from battery to components and vice versa. This flow is possible only through this device. After the current passes from the battery to the AC-DC inverter, it has to be balanced for the safety of the EV’s components. The current might be either very high or very low, which a bidirectional DC-DC converter stabilizes. 

If it is not installed inside an EV, the fluctuations in voltage will damage the sensitive components. The EV will not be able to perform well unless such devices are installed in it. If there is no stability, an EV will get inconsistent power from the motor. This will create problems for drivers in controlling the EVs. These problems will start to occur since the current will not be able to flow properly.

Protecting the Low-Voltage Parts from Excessive Voltage

Likewise, the components that need low voltage to perform can not survive against a high rate of voltage. They need protection through a bidirectional DC-DC converter. EVs have these built-in devices to perform at the best level. They procure them from suppliers of bidirectional DC-DC converters. The reason they install them is because these converters provide protection. That protection is from high-voltage flow.   

A sudden rise in the voltage can damage lots of components inside an EV. To protect them from these threats, manufacturers have to install bidirectional DC-DC converters. They receive high voltage from the source of supply, and then they reduce the voltage to make it compatible with sensitive components ahead. In this way, they ensure the safety of EV components.  

Boosting the Current for EV Motor

On the other end, these bidirectional DC-DC converters are good at reverse operation. That is about increasing the current for EV motors. Since a battery provides a normal flow of current, a motor needs a boost to perform at a high level. It relies on these converters to boost the current level to get that boost. Once it increases the current, the EV motor successfully performs. There are capacitors as well as resistors installed in them that help these converters reduce and improve the current level. They make the current flow in both directions to fulfill the requirements on both ends. 

A bidirectional DC-DC converter supplier knows about it. This is why EV manufacturers have to install these converters inside their EVs. Otherwise, an EV can not process the conversion between high and low-voltage flows. 

Battery Charging via Braking System

You will be surprised to know that every time a driver applies brakes, the energy generated from it is stored inside the battery. That energy is transferred with the help of the same DC-DC converter. Note that a supplier of bidirectional DC-DC converters has to ensure the right type for that. Since there are different types of DC-DC converters, the right type is installed in it. This type is known for transferring energy in a reverse way to the battery. 

That battery absorbs the energy and reuses it for further processing. This is how brakes regenerate the energy, which is not wasted in the whole process. 

Isolation in High-Voltage Supply and Low-Voltage Components

Some components need to be isolated from the others because of their sensitive nature. There is a barrier between them, which ensures protection of either side from high and low voltage. Again, these converters create a barrier between high-voltage supply and low-voltage components. The current flowing from the battery can not directly impact the components in an EV, not even the motor. One of the many types of DC-DC converters is installed in EVs. They provide stable flow without damaging the components.

Different natures of components inside EVs require different compatibility. If manufacturers do not keep this in mind, EVs will face many challenges. Likewise, the performance will not be like it is expected. This is one of the reasons why DC-DC converters are installed inside them.

Reverse Charging for Grid 

 Not only can a grid charge an EV, but an EV can also charge a grid. That reverse process requires devices like V2G (vehicle-to-grid) and bidirectional DC-DC converters. They enable an EV to supply current to a grid without any risk of damage. You can charge a grid by using such devices with the help of your EVs. These EVs have the potential to supply current back when they have excessive energy in them. The booster-type converter increases the current in this process. Then, large amounts of ions travel rapidly through the capacitors installed in these converters. 

It happens when the grid has an electricity shortage, but the EVs have an excessive supply. Users can supply energy to the grid to charge other EVs. Since direct EV-to-EV charging is not available, V2G technology is suitable for charging other EVs. 

Conclusion

If there is no bidirectional DC-DC converter, an EV can not perform as required. As soon as the voltage fluctuation occurs, disaster can occur. EVs need these devices for safe performance and durability. Hopefully, it will help you.

Revolutionizing Electric Mobility: The Role of EV Charger Modules

It is just about some years and we might be witnessing electric vehicles everywhere. Cleaner air quality and lower damage to the ozone layer with EVs are going to be a reality. Since it is linked to sustainable resources, solar energy, we can consider EVs the best option in the future. There will be the least carbon emission as compared to combustible-fuel vehicles, which consume diesel, petrol (gasoline), compressed natural gas (CNG), ethanol, and even hydrogen. These are the fuels that have been causing air pollution, which is contributing to massive global warming. However, the time is changing, and the severity is leading industries to sustainable options. EVs are taking over the transportation system with their convenient charging system, and cleaner consumption modes. To illustrate, we are about to shed some light on the role of EV charge modules in revolutionizing electric mobility.   Faster Charging to Save Time for Commuters The charging speed is usually 4 hours to 6 hours for an EV, but it depends on the type of module and battery capacity. The role of an EV charger module is to accelerate the charging process. It means that the battery will be receiving the ions in larger bands in a very short time. As the technology is upgrading, the charging modules are also getting smarter. They can evaluate battery conditions to charge accordingly. In recent years, the focus of more electric vehicles on the road has been given. It has opened the gates for faster charging, so people can save time and resources.      Dynamic Conversion of Current In early technology, chargers were limited to only specific types of batteries and modes. As the research and development works are progressing, the conversion of energy is getting faster and more dynamic. You can find options in EV charger modules from AC to DC, AC to AC, DC to AC, and DC to DC. That will make them charge almost every kind of EV whether it is a car or a bus. All it has to do is detect the type of battery and its requirements. After that, it can convert the current accordingly.  This safe conversion is proof of why EV charger modules are revolutionizing electric mobility. In early times, there were many limitations on the conversion of currency. Most chargers were capable of producing only around 7.5 kW power but now, they can produce up to 20 kW. This limit expansion can make EV charger modules more powerful to deal with massive batteries.   Protection of Batteries from Overcharging  Overcharging can damage any battery whether it is an EV or any appliance. When the ions exceed their limit, the battery has to face the damage. This is the problem, which is common with every appliance, which needs charging. However, this problem has been dealt with by the automatic turn-off feature. The most advanced feature of these modules is that they automatically turn off as soon as the battery fully charges.  This feature was made possible through a voltage regulator. It controls the voltage and supply of charge in the battery as per the battery limit. Since EV charger modules have a feature that shows battery levels as soon as the cord is connected. It helps EV users to know about the charging limit and duration just like in cell phones. As a result, the batteries of EVs remain safe from overcharging and overheating. In response, no complaint of battery damage would take place.    Voltage Management to Prevent Fluctuation Voltage fluctuation can damage the battery of an EV. To deal with this problem, advanced EV charger modules have been equipped with voltage stabilizers inside them. This feature saves batteries of EVs from the unstable supply of voltage. The voltage fluctuation is a problem, which can occur anywhere. However, they can handle these problems now. In addition, EV charging modules have active balancing to ensure each cell gets equal charging. This makes the battery receive a balanced voltage. In modern chargers, they have a buffer for electricity storage. When the voltage level drops, these modules use energy from that buffer storage. In this whole system, high voltage is managed into a medium by lowering the flow and vice versa.   Communication Protocol for Machine Intelligence  Another thing is a communication protocol, which helps the EV charger modules to do multiple intelligent tasks. These tasks include integrating the EVs with chargers and also charging stations with back-end control teams. Some of them are OCPP, OCPI, OSCP, etc. In detail, charging points can detect the temperature level, battery level, battery type, EV type, and other information to charge better. Moreover, the back-end support team can work on diagnosing the problems inside the charging modules. It can help to analyze the situation better to overcome the fault in time.   Conclusion  EV charger modules might receive some features like AI and automation in the future, which is not a surprise. This will boost the whole transportation and software industries with unbelievable results. Explore our related blogs. Click here to read more and expand your knowledge.
