Low electricity supply can risk EV safety:Experts say charge to 80%; don’t compromise on wiring

A short circuit in an electric car (Tata Punch) on charging caught fire in a house in Indore. The fire engulfed a three-story building. In the accident, 8 people including rubber businessman Manoj Puglia and his daughter-in-law Simran died, while 4 people were injured. This incident in Brijeshwari Annex Colony shocked the entire area. It should be noted that many people use electric cars these days. In such cases, there are many safety norms regarding car charging that need to be followed. Dainik Bhaskar spoke with automobile expert Harshvardhan Chauhan EV cars are not dangerous, there are certain standards for this According to automobile expert and sales manager of premium cars Harshvardhan Chauhan, EV cars are not dangerous. There are certain set standards for this. The Government of India has also approved it. All tests of the car have been done. Fire in EV cars can occur due to short circuits if voltage fluctuation is very high. A stabilizer is necessary for voltage fluctuation. Battery is not the only cause of fire, there can be other reasons too. Fire can occur due to overheating, short circuit or if using wrong quality local charger, there could be other reasons as well. Because cars only pass according to European safety norms. It’s not that companies don’t take care. They are running in fifty countries. EV car batteries only have cells and there is a Battery Management System (BMS) which controls the power of the entire car. Should not do overnight charging with fast charger This tells you when to charge the car and how much to charge. How the car is running. The EV car battery is sealed and has a fireproof coating on top. It doesn’t catch fire suddenly. EV cars have battery temperature management. If you are using a standard charger, you can leave it charging overnight. If you are charging with a fast charger, you should not do overnight charging. EV cars don’t get overcharged because the battery management system cuts it off, just like in mobile phones. If there is sparking in the meter, the car can catch fire. The risk is higher when the wiring management is faulty or there are load issues. Don’t put the car on charging immediately after arriving from somewhere Automobile expert and sales manager of Premium Car Lounge Harshvardhan Chauhan said that if you have an electric car, it is very important to keep these things in mind. For example, if you come from a long route or after long travel in an electric car, you should never put the car on charging immediately upon arrival. Because the car has already traveled long distance. At that time the car remains hot. Therefore, it should be given a few hours of rest so that the car cools down. The car should only be put on charging after two to three hours. The car should not be overcharged. Normal charger is better than fast charger When you charge an electric car, it is also necessary to have an MCB where you are charging from. This increases security and reduces the possibility of short circuit. Charge electric cars with normal chargers instead of fast chargers, because normal chargers are better than fast chargers. Fast chargers cause the car battery to heat up quickly. If charging overnight, use a normal charger only. Don’t compromise on charger wire quality Harshvardhan says that the quality of wires used to charge the car should be good. Never compromise on wire quality. Additionally, before putting the car on charging, check the charger and wires to ensure no wires are cut. Following these precautions reduces the possibility of accidents. Also check that the plug where you are inserting the pin is not loose. Make sure there is no water around the area. Because in such cases, there is a risk of short circuit. Along with this, keep a fire extinguisher at home so that it can be used in case of an unfortunate incident. Home load should be higher Besides this, keep in mind that if the battery is 8 to 10 volts, the home load should be higher than this. Because there are other electronic items in the house that keep running continuously, therefore the load should be higher so that these items receive less load. Additionally, the safety norms provided by the company should be read carefully. Everything should be done according to those guidelines. Should charge to 80% instead of 100% Harshvardhan says that EV cars should not be charged to 100%. These cars should only be charged up to 80-85%. Try to charge only this much, don’t fully charge. This also affects the battery health. Even if charging overnight, make sure it only charges to 80-82%, because according to norms this is how much it should be charged. The battery deteriorates quickly due to overheating. Don’t park the car in sunlight, use standard charger They say that EV cars should not be parked in sunlight during charging. It should be kept under a shade and in an open space. Because the car can heat up due to sunlight and this can also affect the battery. They say that charging with a standard charger maintains good battery life. The car doesn’t heat up and safety is also maintained. The company provides safety norms with the car, all things should be done only after reading these manuals, so that no problems arise. All this is provided so that customers can read it. GSITS expert Pro Shailendra Sharma said that – Looking at the car’s conditions in the incident, internal causes appear likely. The car is completely damaged. The cable is partially burnt. In such a situation, it’s possible that the battery’s auto-cut system or onboard charger controller failed. This caused the fire and created an explosive situation in the battery. Heating due to loose connections could also be a cause.
