Should New Energy Vehicles Be Charged Daily or Only When Depleted?
4 Answers
New energy vehicles should be charged daily. Reasons for daily charging of new energy vehicles: Currently, lithium batteries are widely used, and completely depleting their charge can cause battery damage. Therefore, when the remaining charge of an electric vehicle drops to about one-quarter, it should be charged at a charging station. Never wait until the battery is fully depleted before charging. Similar to conventional two-wheel electric vehicles, the battery is the most critical component of new energy electric vehicles. Ensuring the battery remains in good condition is essential, as replacements can be costly. Charging process for new energy vehicles: Primarily, an off-board charger is used to directly charge the battery with high current, allowing the battery to reach approximately 80% charge in a short time. Typically, a full charge can be achieved within one hour.
When I first bought this electric car, I was also torn between charging it every day or waiting until it was almost out of power. Later, based on my commuting habits, I found that charging daily was more convenient—driving a few dozen kilometers to and from work uses about half the battery, so I plug it into the charging station before bed and set off with a full charge the next day. A neighbor who drives a ride-hailing car also mentioned that lithium batteries are most afraid of deep discharge, and charging only after depletion accelerates battery aging and shortens overall lifespan. I tried draining the battery completely a few times before charging, and the car noticeably lacked power. A check-up at the dealership revealed unstable voltage, which ended up costing more. Now, I’ve made it a habit to charge once every night, and the battery condition is almost like new. Not only does it save money, but it also eliminates the worry of unexpected power loss, especially during rainy or snowy days, giving me extra peace of mind.
I usually use my new energy vehicle to pick up and drop off my kids at school, making round trips every day. At first, I wanted to save electricity, so I would wait until the battery was almost empty before charging. However, after two weeks, the battery alarm went off. The mechanic reminded me: 'For lithium batteries, shallow charging and discharging is the right way.' Since then, I've made it a habit to plug in and charge the car every evening when I get home, stopping at around 80%. This not only protects the battery and extends its lifespan but also saves money on frequent repairs. Doing the math, shallow charging saves on electricity costs, while deep discharging causes more wear and tear, leading to higher long-term replacement costs. The kids can't be late for school, so ensuring sufficient battery power is a priority. Life experience has taught me not to overcomplicate things—regular charging is the most reliable approach.
I've studied some battery knowledge and understand that the lithium batteries in new energy vehicles are like the human body—frequent deep discharges can lead to overuse. Therefore, my approach is to charge daily and never let the battery level drop below 20%. This keeps the charge-discharge cycles within a safe range, slowing battery degradation. If you wait until the battery is completely drained before charging, the internal chemical reactions become intense when the charge hits zero, potentially causing overheating or permanent damage. After trying shallow charging for a few weeks, the battery's range remained largely unchanged; but after deep discharging, efficiency dropped by 5%. Simply put, daily maintenance is like fitness—small, frequent sessions are healthier than one intense workout.
