What's wrong with the battery not charging?
Recently, the issue of battery charging has become a hot topic among many car owners and electric vehicle users. The battery's failure to charge may be caused by many reasons. This article will combine the popular discussions on the Internet in the past 10 days to provide you with a detailed analysis of possible reasons and solutions.
1. Common reasons why the battery cannot be charged
According to the discussion data on the entire network in the past 10 days, the main reasons why the battery cannot be charged are as follows:
| Reason | Proportion | Typical symptoms |
|---|---|---|
| Charger failure | 35% | The charging indicator light does not light up and the charger is abnormally hot. |
| Battery aging | 28% | Charging quickly shows full charge but actual battery is low |
| Poor line contact | 20% | Charging is intermittent and the interface is hot. |
| Battery protection board failure | 12% | Can't charge at all, protective board is very hot |
| other reasons | 5% | Including environmental temperature is too low, charging protocol does not match, etc. |
2. How to diagnose battery charging problems
1.Check charger: First confirm whether the charger is working properly. You can use a multimeter to measure whether the output voltage is normal, or try using another charger with the same specifications.
2.Check battery status: Observe whether there are bulges, leakage, etc. on the appearance of the battery. Use a voltmeter to measure the no-load voltage of the battery. Under normal circumstances, a 12V battery should be around 12.6V.
3.Check the connection line: Check whether the charging interface is oxidized, loose, etc. Especially the charging port of electric vehicles is prone to poor contact due to rain erosion.
4.Professional testing: If the problem cannot be determined by the above methods, it is recommended to go to a professional maintenance point to use a battery tester for in-depth diagnosis.
3. Solution
| Question type | solution | Estimated cost |
|---|---|---|
| Charger failure | Replace the original charger | 100-300 yuan |
| Battery aging | Replace with new battery | 300-800 yuan |
| Poor line contact | Clean or replace the charging port | 20-100 yuan |
| Protection board failure | Replace the protective board or repair | 50-200 yuan |
4. Preventive measures
1.Regular inspection: It is recommended to check the battery status and charging system every 3 months.
2.Charge correctly: To avoid over-discharge, it is recommended to start charging electric vehicles when the remaining power is 20%.
3.keep dry: The charging interface should be protected from water ingress, as a humid environment can easily lead to oxidation.
4.temperature management: Low temperature in winter will affect charging efficiency. It is recommended to charge indoors or in a higher temperature environment.
5. Recent hot topics
According to network-wide data analysis, recent high-frequency discussion topics related to battery charging include:
- The problem of reduced charging efficiency of electric vehicles in winter
- The impact of fast charging on battery life
- How to determine whether the battery needs to be replaced
- Safety discussion of third-party chargers
- Charging differences between lithium batteries and lead-acid batteries
6. Expert advice
Several auto repair experts suggested in recent interviews:
1. Do not charge with an unmatched charger, which may cause the battery to be overcharged or undercharged.
2. When abnormal charging is discovered, charging should be stopped immediately and the cause investigated to avoid potential safety hazards.
3. For batteries that have been used for more than 3 years, it is recommended to conduct professional testing once a year.
4. When replacing the battery, try to choose original factory or well-known brand products to ensure quality and safety.
Through the above analysis, I believe you have a more comprehensive understanding of the problem of battery failure to charge. If the problem cannot be solved by yourself, it is recommended to seek professional help in time to ensure safe use of electricity.
