Learn about the robust safety measures in place to ensure your electric vehicle's battery is not just a power source but a secure one. We've got your back on the road to a safer, cleaner tomorrow.

Discover what makes your EV batteries safe

Learn all about the robust safety measures that ensure EV’s battery is not just powerful, but also secure.

The “Safety First” Design Approach

Electric vehicle batteries are designed meticulously to endure the test of time and work under varied weather conditions. To achieve this, EV batteries undergo rigorous safety testing.

Temperature management- EV batteries excel in temperature regulation. They employ advanced thermal management systems to prevent overheating and enhance safety.
Stringent testing- Before they find a place in your vehicle, EV batteries are subjected to some of the most rigorous safety tests. These include extreme weather simulations and physical impact tests and testing performance with local road and weather conditions.
Safety Enhancements- EV batteries also come with multiple layers of safety features such as protective casings, fail-safe circuits, and advanced software algorithms that monitor battery health in real-time.

Thoroughly tested for a reliable drive

Batteries used in electric cars undergo rigorous testing for almost every imaginable road condition, including those rare ones you'd likely never encounter. Before becoming the heart of your vehicle, your EV battery faces many extreme situations.

Sophisticated computer simulations further assess its behaviour across a myriad of conditions. So, as you drive down the road, know that your EV's battery isn't just efficient—it's exceptionally reliable.

Your bit in ensuring battery safety

Safety isn't just about the initial design; it's also about maintenance. Here's how you can ensure the longevity and safety of your EV battery

Maintain proper charging habits.
Regular software and firmware updates.
Scheduled maintenance checks.

Factors affecting the performance of EV batteries

EV batteries can be affected due to various reasons, some of them are:

Thermal runaway

A rapid increase in temperature and pressure within the battery cell leading to destabilising and degradation of battery content. Though lithium-ion batteries are a part of the BMS (battery management system) which regulates the current flow and battery temperature while charging the batteries, one can still follow the simplest ways to ensure extra safety,

EVs should be charged in well-ventilated open spaces to maintain the temperature of the batteries.
Avoid charging beyond the standard and recommended charging time.
Ensure Regular vehicle service and checkups

Overcharging or undercharging

A condition where the battery is charged beyond its capacity which can lead to early deterioration of battery's state of health and performance. Timely and mindful charging can protect the battery from early-stage damage.

Mechanical damage

A physical impact or deformation of the battery due to a physical impact might to lead internal damages in certain cases which can affect the battery performance hence, an immediate follow-up checkup with the vendor will ensure battery health and safety to the customer. The authorised vendor will check for any damage caused to the battery and take necessary actions to safeguard the vehicle.

Cell imbalance

A mismatch in the state of charge or state of health of the individual cells in a battery pack, resulting in reduced performance, accelerated degradation. Imbalanced cells lock away otherwise usable energy and increase battery degradation. Batteries that are out of balance cannot be fully charged or fully discharged, hence keeping an eye on the discharge pattern of the battery and immediately reporting in case of anomaly.
