When the battery can't power... Why does the customer finally become
When the battery can't power... why finally the customer becomes wrong?
Over the years, solar hybrid and energy storage systems have become more popular in homes and factories because they can reduce power bills and power reserves, but in practice they have been found.
# One problem that happens oftenIs
Battery systems have power tripping, cutting inverters or downtime.
And what customers often get as an answer is,
"Customers use overload."
"Customers can't use the system."
Is the problem real or the quality of the battery system?
This paper will technically explain how such problems arise.
# Symptoms often seen in low-quality battery systems
Problematic battery systems often show symptoms of this nature.
Battery. Discrete power supply.
As the load increases, the pressure falls immediately.
The inverter occurs Trip or Shutdown.
The system intermittently stopped working.
Sometimes, even though the load is not very high, the system still has a stumble.
The inverter is defending himself.
When the battery voltage falls below a certain value, the inverter immediately cuts off operation to prevent system damage.
Technical reasons why power supply batteries are unstable
1.High battery internal resistance
Batteries that use low quality or poorly designed cells often have high Internal Resistance.
When there is a high current load, e.g.
Water pump
Air Conditioning
Motor
Factory machinery
The current will increase immediately, causing the battery voltage to drop rapidly.
The consequences are
The inverter detected a low pressure.
The system then immediately cut off operation.
Even the battery still has energy left.
2. The BMS system responds slowly.
The BMS (Battery Management System) is the brain of the battery.
Charge control
Discharge control
Prevent overcurrent
Check the temperature.
If the BMS is of poor quality or poorly designed, problems occur.
Slow load response
Misrhythmic circuit cutting
The protection system runs ahead of time.
The result is
The battery stopped powering. Even the load was still within the limits that it should have been received.
3.SOC of battery is not accurate
Another common problem is
SOC (State of Charge) distorted
Such as
Show 40%, but actually only 10% left.
Or a bad cell balance system.
As the load increased, the system understood that the battery was running out and cut off the power supply.
4. The system design does not support the actual load.
Many times, the problem is not that customers overuse fire, but caused by
Designing a system that does not understand the behavior of the load.
For example,
The motor has a surge current several times higher than normal.
Air Conditioner with Compressor Start Current
Industrial machinery has a high Peak Load.
If the battery system cannot support Transient Current,
The inverter will cut immediately.
Why are users being blamed for "not being used?"
In many cases, vendors or installers without sufficient engineering understanding often describe the simple problem as
Customer overloaded
The customer turns on too much at the same time.
Customers don't use it the right way.
In fact,
A well-designed system should support practical application behavior.
Users shouldn't have to sit and watch that.
Turn this on?
Open at the same time?
Will the system cut?
# What should a good battery system qualify?
To keep the system running stable, the battery should have the following key elements.
1.High quality battery cell
It reduces internal resistance and supports high currents.
2.Precise BMS system
It can control and respond quickly to loads.
3. Effective cell balancing
This makes SOC accurate and reduces system fault cutting.
4. Designing the system to support the actual load.
By having to calculate
Peak Load
Inrush Current
The practical use behavior of users.
# Conclusion
Power supply battery problems stumble or cut-off inverters. Not always caused by "users are not."
In many cases, the real reason is
Battery quality
BMS system
Improper system design
Or inconsistent device selection.
A good power system should be designed to operate stable without the user having to worry about turning off the device.
Because in the end,
Good technology should help solve problems for the user, not create new problems for him.
