From Right Equipment To Overcharging: DOs & DON’Ts Of EV Battery Charging
Charging EV batteries incorrectly can result in overheating, fire, or other safety hazards.
There has been a rising awareness among Indian commuters on the need to avail clean mobility to contribute towards reducing the country’s carbon footprint, driving the massive popularity of electric vehicles. The clean and green EVs have now emerged as the most viable choice for transportation for multiple factors like user-friendliness, effectiveness and eco-conscious designs. While the demand for EVs is significantly on the rise, there is also a need to address another issue – the need for a robust EV battery charging infrastructure.
Understanding how to properly charge and maintain the battery that powers electric vehicles is essential for extending its lifespan and guaranteeing peak performance. Charging EV batteries incorrectly can result in overheating, fire, or other safety hazards. Following manufacturer-recommended charging guidelines reduces the risk of accidents. Also, charging at the recommended voltage and current levels ensures that energy is transferred efficiently to the battery. Even though many EV manufacturers in India offer charging demonstrations, there are certain obvious dos and don'ts that we all fail to notice.
Let’s explore some of the DOs and DON’Ts EV users should consider to charge their vehicles in the best possible ways to ensure better safety, maximized lifespan and enhanced efficiency.
DOs
Recharge after every ride
EV users must recharge their vehicle’s battery after every use to ensure the best performance. Recharging stops the battery from gradually losing capacity even if it is not totally discharged. Repeatedly charging the EV when the battery is not significantly depleted (known as "topping off") can have a minor impact on the overall battery health over time. However, modern EVs are designed to manage this, and the effect is typically minimal.
Choosing the right charging equipment
A unique charger is needed for each battery. Therefore, it is essential to utilize the charger that the e-rickshaw battery's manufacturer has given. The improper charger might limit the life of the battery and cause damage. Users must also ensure that they have the appropriate charging equipment for their EVs. Choosing the right charger for the EVs is essential to ensure efficient charging and compatibility with the vehicle's battery system. As EV technology evolves, it's a good idea to think about whether the charger will be compatible with future EVs if one plans to replace the current electric vehicle.
Keep the battery cool and avoid extreme temperatures
Extreme heat or cold can impact battery health negatively. Gases and heat that are produced during battery charging must be properly let out. By charging the EV battery in a well-ventilated area, users can lessen the possibility of overheating and a fire hazard.
Charge to full only when necessary
Charging to 100 per cent is usually only necessary when you have a long journey planned. Extended periods of high SoC can contribute to battery degradation.
Charge the battery when cool
A heated battery might be damaged and have a shorter lifespan if it is charged. To prolong the battery's longevity and functionality, it is advised to let it cool down before starting the charging process.
DON’Ts
Overcharging or frequent charging can be counter-effective
An electric vehicle’s battery lifespan may be negatively impacted by overcharging it. For this reason, the majority of Indian makers of electric rickshaws advise adhering to the prescribed charging time and not leaving the battery attached to the charger for longer than necessary.
Batteries should not be discharged entirely
The battery's lifespan can be shortened and damaged if users let it deplete fully. To maintain the battery's durability and guarantee continuous operation, batteries should be recharged before they reach a dangerously low level.
Don’t store the battery in a hot and humid environment
A hot or humid atmosphere can shorten the lifespan and cause the deterioration of a battery. To reduce the danger of damage and keep the battery in top condition, it is essential to store it in a cool, dry location.
