Modern life cannot do without various electronic devices, and battery charging system and endurance are one of our most concerned issues.
This article is using electric vehicles battery charging system as an example giving a detailed guide for users to know more about battery charging. In addition here are also some useful maintenance tips for users’ batteries used in other kind of electric instruments.
What is a battery charging system
A well-designed battery charging system includes a charging management chip that is responsible for controlling the charging process (constant current → constant voltage → trickle current) to ensure the safe charging of the battery. External chargers provide suitable voltage and current (such as chargers). Balancing circuit (only required for multiple battery packs) balances the voltage of multiple battery cells.
A single lithium ion battery pack (single cell) usually does not have a complete charging system, but relies on external devices (such as chargers or built-in charging modules) for charging management.
The charging system of electric vehicles is slightly different. Let's take a look at the composition of the battery charging system of electric vehicles.
The components of battery charging system
The battery charging system mainly consists of a battery, a generator, a regulator, a charging indicator light, and a charging circuit. The generator is the main working power source for the entire operation of the car. During normal operation, it supplies power to all electrical equipment except for the starter motor and charges the battery. Vehicle generators are divided into two categories: DC generators and silicon rectifier AC generators. DC generators have been replaced by AC generators due to their complex structure, large size and mass, and high charging speed.
What is the battery charging method
The positive electrode of the battery is generated from lithium ions, which jump into the electrolyte and climb through the winding holes on the separator to move to the negative electrode, where they combine with electrons that have already run to the negative electrode through an external circuit.
How do I fix my battery charging system
The charging system of batteries varies depending on the device used. Taking the charging system of electric vehicles as an example. When the battery charging system triggers a warning light on the dashboard of an electric vehicle and it is constantly on, it means some failures in the battery charging system.
The reason and solution for the constant illumination of the charging indicator light is caused by the aging of the battery, because after the battery ages, battery storage and battery discharge capacity will sharply decrease, which will trigger the charging indicator light warning on the instrument panel. The battery life of a typical car is about 2-3 years. It is recommended that car owners keep a power bank in their car. This way, even if the battery ages and experiences a power loss, they don't have to spend money to find someone to power it on and can solve the problem themselves.
The solution to this type of malfunction is to replace the battery a necessary componet in the battery charging system with a new one. However, it should be noted that the positive and negative poles should not be reversed during the replacement process, otherwise it may burn out some control modules. In addition, even after replacing the battery, the charging indicator light still stays on. To solve this problem, simply match the newly replaced battery.
The second is caused by the damage of the generator. After it is damaged, the vehicle will no longer generate electricity. When the ECU detects that the generator is not generating electricity, it will light up the charging indicator to warn, because at this time, all the electricity used by the vehicle comes from the battery. If left for a long time, it will also cause damage to the battery. In addition, damage to the wiring harness related to the generator can also cause the same problem, such as short circuiting of the excitation line or open circuit of the signal feedback line. To solve this problem, only the damaged wiring harness needs to be repaired.
The solution to this type of malfunction is to recommend replacing the generator as soon as possible to avoid damaging the car battery if driving for a long time.
The third issue is the breakage of the belt that drives the generator, which can also cause the vehicle to display a charging indicator light. This is because most car models still use belt driven generators. If the belt breaks, it is equivalent to the generator not working, and it will also be accompanied by heavy steering, no braking, stalling and other faults.
The solution to this type of malfunction is to replace the generator belt and reinstall it. If the car owner encounters such a situation while driving, it is recommended not to continue driving. Because prolonged driving can cause battery depletion, vehicle failure to start, and other malfunctions, and there are also many dangers in continuing to drive without the generator working.
Fourthly, the current sensor on the battery is damaged. This sensor will detect the direction of the current on the battery and calculate the battery capacity and working status based on the direction of the current. If the current is flowing in the direction of the battery, it indicates that the battery is currently charging; If the current flows in the opposite direction, it indicates that the battery is discharging. If it is damaged, it will cause the current signal to not be detected, resulting in the malfunction light being on.
The solution to this type of malfunction is to replace the sensor with a new one.
What does service battery charging system mean
When the dashboard of an electrical device displays a prompt message asking for maintenance of the battery charging system, it usually indicates that there may be a malfunction in the vehicle's battery charging system. The sources of such faults may be diverse, including but not limited to generators, related electrical equipment, and the connecting lines between them.
The battery management system module is burnt out or damaged, causing it to malfunction. At this point, it is necessary to replace the battery management module with a new one to restore the normal function of the battery.
Damage to other components in the charging system, such as charging cables or fuses, may cause malfunctions in the charging system.
The battery itself has problems such as aging, leakage, etc. Need to check the battery status and take appropriate measures.
It is recommended to promptly contact professional maintenance personnel for inspection and repair when such problems occur to ensure safe use.
Battery maintenance advice from Tycorun
Mastering the correct battery maintenance methods can effectively extend battery life and make equipment last longer.
Avoid overcharging and overdischarging
Try to keep the battery level between 20% and 80% and avoid being in a fully charged or depleted state for a long time.
Charge as needed
Don't wait until the battery is depleted before charging. You can charge it anytime, but don't always fully charge it.
Use original or certified chargers
Poor quality chargers may damage the battery and even pose safety hazards.
Avoid high temperature charging
Try to remove the phone case when charging to avoid charging in high temperature environments.
Avoid wireless charging
Try to avoid wireless charging when charging mobile devices, as wireless charging generates more heat and is detrimental to battery life.
Battery maintenance for different electric instruments
-
Mobile phone
Use official or reliable battery health monitoring tools to monitor battery health.
Regularly clean the phone's memory and close unnecessary background programs.
Avoid using inferior power banks.
-
Notebook computer
Use power management software to select the appropriate power mode.
Avoid prolonged high load operation, such as playing games, video editing, etc.
Regularly clean the cooling fan to maintain good heat dissipation. When not in use for a long time, it is recommended to keep the battery level at around 50%.
-
Electric vehicle
Avoid frequent rapid acceleration and braking.
Regularly check tire pressure and maintain normal tire pressure.
Avoid charging in high temperature environments and choose a cool and ventilated place as much as possible.
When not in use for a long time, it is recommended to charge it every month.
In addition, be careful to avoid physical damage to the battery. Keep the battery clean and regularly clean the battery contact points to prevent poor contact. Timely update the system, which usually includes battery optimization improvements. Pay attention to battery health.
If you notice a significant decrease in battery life, it is recommended to replace the battery in a timely manner.
