How to fix Ev Cars Battery Problems: The trend of electric vehicles (EV) is increasing day by day. Increasing prices of petrol and diesel, environment awareness and government policies have made EVs rapidly popular. But with this, a common question comes in the mind of every EV user, why does charging take so much time? Even though many electric vehicles are now coming up with fast charging features, the speed of charging still depends on many factors. There are some things that by understanding and adopting you can improve the charging speed of your EV and save time. Let’s know the important things that affect the charging speed of your electric car and how you can increase it.
1. State of Charge – SOC
When to charge the EV, it has a major impact on its charging speed. When the battery is completely empty (eg 10% or less SOC), it is rapidly charged. As the SoC increases (eg 80%), the charging speed starts to slow down. This is a security feature to protect the battery from overcharging.
What to do-
Do not keep the EV on too much charge. For better charging speed, start charging at 10% to 20% SOC and only charge up to 80%.
2. Battery Temperature
EV’s battery is thermal sensitive. Very cold or warm temperature directly affects charging speed.
Its ideal temperature
It proves to be safe between 10 ° C to 30 ° C.
Charging gets slow in high heat and battery life is also affected.
Even in the cold, the battery is slowly charged as the speed of electrolytes slows down.
What to do-
In summer, park the car in shade and charge.
Before charging in winter, drive the car for a while so that the battery becomes hot.
3. Other electric loads used during charging during charging during charging
It can reduce charging speed if you use AC, headlight or infotainment system of the car during charging. Due to this, the energy coming from the charger is divided on two places in the battery and other loads. As a result, the battery is slowly charged.
What to do-
Keep AC, music system, cabin lights and other electric equipment off when charging.
4. Battery age and condition
Over time, there is degradation in the battery of the EV. This reduces both his charging capacity and speed.
The old battery is more hot and is gently charged. Frequent full charge and full discharge causes the battery to deteriorate quickly.
What to do-
Never finish the battery up to 0% and do not take up to 100% again and again.
Adopt charging routine between 20 to 80 percent.
From time to time, do the battery tested and maintained.
5. Power output of the charging point of charging point
Your charger’s capacity and power output is a large factor of charging speed.
EV has charging capacity (eg 7.2kw, 11kw, 50kw or 120kw).
If you are charging a 50kw capacity vehicle with just 3.3kw charger, charging will be slow.
What to do-
Learn the maximum charging capacity of your EV.
Accordingly, choose the charging station.
Where possible, use DC fast charger.
6. EV Charging Infrastructure and Network
A reliable and strong charging network is required to charge EV correctly. At some places charging stations are low in power output. Sometimes technical fault in network can also reduce charging.
What to do-
Use reliable charging stations such as Tata Power, Ather Grid, Chargezone, Statiq etc. Book a charging slot in advance to save time (where the facility is available).
7. Quality and length of charging cable
Charging can affect the quality of cable and the power charging speed that can be borne by it. Does not transfer bad or old cable power properly.
Long cables can cause voltage drop, which slows charging.
What to do-
Use a certified cable given by the company. Inspect the condition of the cable from time to time. Avoid very long cables.
8. software and firmware updates (software and firmware updates)
Many times the software updates that control charging speed come.
The new update can improve battery charging efficiency. Many times companies reduce charging speed due to security reasons.
What to do-
Always keep your EV software updated.
Get the service center tested from time to time.
9. Difference between AC and DC charging (AC vs DC Charging)
The type of charging also affects the speed.
AC charger gives slow charging (from 3.3kw to 11kw).
At the same time, DC Fast Charger EV can be charged in a few minutes (from 30kw to 350kw).
What to do-
Use AC charger for regular charging at home or office.
Use DC charger for fast charging during travel.
10. Smart Charging Technology and Mobile Apps
Now many EV companies provide smart charging facility, which can control charging according to the battery. Through mobile apps, information about battery status, temperature, charging level etc. is available. You can schedule charging such as the night when the electricity rate is low.
What to do-
Install your EV brand’s mobile app.
Monitor battery and use schedule charging. The charging speed of the electric car is not the same. It depends on many factors such as battery status, temperature, power of charger, vehicle charging limit, etc. If you keep all these things in mind and charge your EV correctly, charging time can be reduced and the age of the battery can also be increased.
Wise charging not only saves your time, but also maintains your EV in a better position for a long time.
