All of us are well aware of the electric vehicles currently and we also know that all these vehicles get energy through the batteries in them. But do you know anything about the design and basic structure of these vehicles? If not, today we are going to give you the most important information about their batteries, you will know everything about electric batteries in this article. The battery of an electric vehicle is designed in such a way that it can meet all the requirements of running and charging the electric motor fitted in all-electric vehicles.
The design of electric batteries and the location of them in an electric vehicle is controlled in such a way that the performance and mileage of the vehicle are not affected. In electric batteries, mainly thousands of small cells are placed in a series, parallel to get voltage and power as per the requirement. For example, a battery that produces 400 volts usually has 96 series in a parallel block of cells. Typically 100–200 volts is required for a hybrid/plugin vehicle and 400–800 volts for electric vehicles only. In general, the battery capacity required varies from vehicle to vehicle.
- Hybrid vehicles – 0.5 to 2 kWh
- Plug-in/hybrid vehicles – 4 to 20 kWh
- Only Electric vehicles – 30 to 100 kWh
Now let’s talk about the safety of the battery because the battery always generates high voltage, so it is equally important to keep them safe, let me tell you, this is not such an easy task and it is quite a messy task. Positive and negative fuses in these batteries, which leads to output connector through high current flow and there is a possibility of mixing in the middle. If the internal welding is not equal then there is always the risk of a big accident from high current.
For this reason, a special pre-connector is installed in these batteries which slowly transmits the high current to the resistor in small parts so that the high current does not reach the direct output connector and the battery management system knows the short circuit and any other fault before High current completes the full path.
Finally, we will tell you about the battery management system, its main function is monitoring and controlling so that any accident can be prevented beforehand. The battery management system always collects a lot of information such as total charge status, voltage measurement and many other conditions so that the driver is already aware of every situation. The battery management system is also always in contact with the charger and inverter, so that it keeps on getting complete information about the health of the battery and also provides the same information to other systems in the vehicle so that the vehicle keeps functioning well.
