For the last several weeks I noticed that the Li Battery gets less and less charged, the charge cycle turns off at 93.5% by now. The charge slows down once the battery voltage on the BMV reaches 14.2V, though for the parameters enabled it should stop charging at
3.6v (14.4v) = end amps tail current C/20 3.55v (14.2v) = end amps tail current C/60 3.5v (14.0v) = end amp tail current C/100 3.45v (13.8v) = end amps tail current = zero When guys didn''t pay attention to this, what was found was degradation due to overcharge. This added up quickly, because they were charging in cycles faster than we do, but
Charge Controllers: For Controlling the electric flow from the solar panels to the batteries these are integrated as a component collection in the off grid solar systems. These regulate the voltage and current that reaches the battery, preventing it from overcharging. Current charge controllers are equipped with myriad sensors and alarms which are activated whenever values exceed
It seems due to the solar system charging the batteries, i have to keep the charged voltage higher then when charged by a battery charger. This has to do with fluctuating voltage from the MPPT.
2 天之前· Considering the widespread use of PHEVs in advanced societies and the issues ahead, researchers'' thinking has focused more on this issue. The important issue is that the
Constant current charging techniques are tested to determine charge efficiency. The larger the electric charging currents, the greater the effective energy stored. Larger charging current rates provoke higher temperature increases in older than newer batteries.
Float only means no net charging current goes into battery. Full charging depends on fully completing transfer of lithium ions into graphite. If you are at or above 3.43v and charging current has dropped to near zero it is fully charged. Some chargers exit absorb stage based on charge current taper down. Some chargers just hold absorb for a set
Charge Controllers: For Controlling the electric flow from the solar panels to the batteries these are integrated as a component collection in the off grid solar systems. These regulate the
With your very simple manual control solar charging, and I guess a low charge current, by the time you reach the target voltage of 14.7 the battery will be at a high state of charge. But it wont be fully charged and over
When a controller fails to regulate the charging current properly, it can lead to excessive voltage being delivered to the battery, causing overcharging. To prevent this issue,
Leisure batteries are designed to provide low currents for long periods of time and then to be recharged relatively slowly. This is the opposite of a car battery which has to provide a very high current to start the car and then is very quickly recharged by the car''s alternator. The rate at which a leisure battery is charged is therefore
Charging current wise--For "longest" life, around 10% to 13% rate of charge for Lead Acid type batteries is recommended. And if your controller has the option, use a remote temperature
When a controller fails to regulate the charging current properly, it can lead to excessive voltage being delivered to the battery, causing overcharging. To prevent this issue, it''s essential to pay close attention to the charging parameters and make sure they''re set correctly.
Marinehowto has exposed the risk vs the reward but but don''t understand why very smart knowledgeable people continue to to charge to 14.4 relying on their BMS to balance when this can be avoided almost without
When a controller fails to regulate the charging current properly, it can lead to excessive voltage being delivered to the battery, causing overcharging. To prevent this issue, it''s essential to pay close attention to the charging parameters and make sure they''re set correctly. Regulate Current: The controller must effectively manage the flow of current to the battery to
If you go higher amps, you will see the charging voltage be higher, the charger is working against the resistance of the battery but still held at 14.8V. Once I see the amps below 3A, I will switch to 13.5V for float.
For a lead-acid battery, it''s charging at 14.4V, but once fully charged, the resting voltage of the battery itself will drop back down to about ~12.7V. This depends on battery chemistry, and other factors like ambient temperature. Li has a more flat voltage curve, so voltage is not as good an indicator of charge as for lead-acid.
It seems due to the solar system charging the batteries, i have to keep the charged voltage higher then when charged by a battery charger. This has to do with fluctuating
If the voltage were high enough, the battery would receive a charge, regardless of the amount of current. That''s how trickle chargers work. You can buy ones that go as low as 0.75A, yet they still charge a battery because they are outputting 14+ volts. It''s the voltage that forces the current to flow in a certain direction, from high voltage to
Although the battery is in "low-voltage disconnect" mode, it will still allow a charging current. (Note: many chargers must detect a voltage over 10v to send a charge to the battery). High temperature: > 135F The BMS will not allow a charging or discharging current. Low temperature: < 25F The BMS will not allow a charging current. High Current

14.4V is the sweet spot because 14.6V requires perfect cell balance to achieve safely. 14.8V is likely to trigger BMS over-voltage protection - not something you want to count
Salee, Slow cranking is more like 8V. If you check around you will find that cranking amps is specified at a very low voltage. After 10 minutes the engine is warm! With 14.4V fixed voltage charging you probably will not get anything near 70 amps charging. I would consider that 14.4V more like a "High" trickle. If it was continuous (car always

Depending on how long a pack is allowed to saturate at low current and the condition of its cells, your resting voltage could be higher or lower. But at 13.5v, it would take DAYS of low current
Any issues charging a higher voltage bank from solar array? If the inverter comes configured as 144v and i get a charger that can do the 144v charging, what other issues are
Depending on how long a pack is allowed to saturate at low current and the condition of its cells, your resting voltage could be higher or lower. But at 13.5v, it would take DAYS of low current charging to saturate the cells up to 100%. That''s why one typically charges to 14.2 / 14.4v, because only then are you out of the flat part of the curve
14.4V is the sweet spot because 14.6V requires perfect cell balance to achieve safely. 14.8V is likely to trigger BMS over-voltage protection - not something you want to count on for routine charging. SOK''s comments are the most relevant.
Overcharging problems in solar charge controllers can substantially impact battery life and pose potential safety hazards. When a controller fails to regulate the charging current properly, it can lead to excessive voltage being delivered to the battery, causing overcharging.
High solar panel output voltage poses a significant risk to batteries and connected devices due to its potential to cause damage and reduce lifespan. When the solar panels generate high voltage, it can lead to overcharging, which is detrimental to the battery lifespan.
When the solar panels generate high voltage, it can lead to overcharging, which is detrimental to the battery lifespan. This issue may stem from a malfunction in the MPPT solar charge controller or the solar panels themselves.
Perhaps potential is not the technically proper word. For a lead-acid battery, it's charging at 14.4V, but once fully charged, the resting voltage of the battery itself will drop back down to about ~12.7V. This depends on battery chemistry, and other factors like ambient temperature.
To troubleshoot, check for shading on the panels, faulty wiring connections, or incorrect settings on the charge controller that could be causing the high voltage output. Addressing high solar panel output voltage promptly is essential to prevent potential damage to the system components and guarantee performance.
Loose connections can lead to inefficiencies and malfunctions. Inspect for Damage: Regularly inspect for any signs of damage to the load output terminals. Damage can affect the overall performance of the solar charge controller. Evaluate Insulation: Verify that the insulation on the load output terminals is intact.
