Electric vehicles are powered by a battery, which can be charged and discharged to provide energy. Electric vehicle topology is the way batteries are arranged within a car. Electric vehicles with single-battery modules are called series-parallel topologies.
This topology is found in many electric vehicles, such as the Tesla Model S and BMW i3. In this electric vehicle topology, the battery on one side of the car powers a motor, while the battery on the other side of the car powers the other motor.
Electric vehicles with two-battery modules are called series-parallel-series topologies. This configuration is found in many electric cars, including the Tesla Model S P100d and BMW i3s. In this topology, one battery charges and powers the first motor, while the second battery charges and powers the second motor. in a series-
The electric vehicle topology includes three different options:
- A single battery pack on the floor of the car
- Two or more parallel batteries in series on one side of the car
- Two or more parallel batteries in parallel on both sides of the car
Why Was the Electric Vehicle Topology Needed?
Let us tell you that the need for topology in an electric vehicle arose because the electric vehicle needs more batteries to run for a longer time. This type of new technology has been invented to charge more batteries. This has dramatically benefited electric cars. This technology has changed the way the vehicle is charged. Thus the need for an electric vehicle topology arose.
Electric Vehicle Battery Pack Technology
Today we will discuss Electric Vehicle Battery Pack Technology. The battery pack is an essential part of an electric vehicle. This is what drives the vehicle, and it supplies power to the motor. The vehicle cannot move with its help.
A battery pack comprises several cells composed of the battery cell chemistry. The battery pack design includes how many cells are used in each group and the methods used for each cell type. Before making the battery pack, the complete procedure is done as to how the battery pack will be made.
The technology behind batteries has undergone significant changes over the years, as has their use in various industries and applications. These changes made it possible to reduce costs, increase efficiency and improve performance. The battery technology in use at present has been entirely advanced. The battery pack used in most electric vehicles is completely advanced in itself. New features have been added to all these, due to which it gives a good performance.
Types of Electric Vehicle Topology
- Series topology
- Parallel topology
- Power split topology
Series topology: The electric motor is connected directly to the battery in a series topology. This type of topology is simple and efficient but does not allow for regenerative braking.
Parallel topology: In a similar topology, the electric motor is connected to the battery parallel to a generator. This type of topology allows for regenerative braking, but it is more complex and less efficient than a series topology.
Power split topology: In a power split topology, the power from the battery is split between the electric motor and the generator. This type of topology is the most complex but is also the most efficient and allows for regenerative braking.
Here are some of the advantages and disadvantages of the three main EV topologies:
- Simple and efficient
- Less expensive
- Easier to maintain
- It does not allow for regenerative braking
- Not as powerful as other topologies
- Allows for regenerative braking
- More potent than series topology
- Easier to install in existing vehicles
- More complex and less efficient than series topology
- More expensive to maintain
Power Split Topology
- Most efficient and powerful topology
- Allows for regenerative braking
- It can be used in a variety of vehicles
- Most complex and expensive topology
- More difficult to maintain
The future of EV topology will likely see a move toward power-split topologies as they become more affordable and efficient.
