How Does a CT Scan Work In A Bus with UPS?

A CT scan generates large amounts of data, which are stored in the machine's memory or on external storage devices. A power outage during a scan can cause data loss, leading to the need to repeat the procedure, which is time-consuming and costly.

Any disruption in the power supply can lead to a malfunction in the machine, causing it to shut down unexpectedly or produce inaccurate results. This can put the patient's life at risk, especially if the scan is being conducted for an emergency medical situation.

CT scan machines are highly sensitive and expensive equipment. They require a stable power supply to avoid damage caused by power surges, voltage spikes, or brownouts. Frequent power disruptions can cause wear and tear on the machine's components, leading to costly repairs or replacements.

CT scans require a high level of precision and accuracy to provide reliable results. Any power interruption or fluctuation can cause the machine to produce distorted images or inaccurate data, compromising the quality of the scan and affecting the diagnosis and treatment plan.

UPS is crucial for the effective operation of CT scan machines in mobile medical units. Any disruption in the power supply can cause significant damage to the machine, endangering the patient's life, and increasing costs for repairs and replacements. By installing reliable UPS systems, mobile medical units can ensure a stable power supply for their CT scan machines, providing accurate and reliable medical care to underserved communities.

The inverter has 220V output terminal and 380V output terminal.
When there are city gird to supply power to the CT machine

The city grid will work bypass to the CT machine, and charge the battery at the same time.
What does bypass means? It means the city grid will supply power directly, not through the inverter. And what power city grid input, the same for output.
But if the city grid not stable, the output will not stable.
So when the city grid not stable, the inverter will switch to use the battery power.

The DC current from battery will invert into stable AC current via the inverter.
In this working mode, it will increase the lithium battery working time. Because if there are stable city grid input, the city grid will work bypass, not use the lithium battery power.
And if some place city grid not stable, the inverter will switch to use the battery power.
Why the power will stable output via the inverter? Click here to understand why.

And the screen will show the working status, how many % battery left.

If the city grid not stable, cannot use directly, and the battery power not enough. The doctors will use the city grid to charge the battery and use the CT machine at the same time.

The lithium battery power is 384V 150Ah.

Battery management system (BMS) is technology dedicated to the oversight of a battery pack, which is an assembly of battery cells, electrically organized in a row x column matrix configuration to enable delivery of targeted range of voltage and current for a duration of time against expected load scenarios.

There are BMS system outside the lithium battery cabinet. BMS stands for battery monitor system, its a small computer, which showing the all the lithium battery information. Like the voltage, current, capacity, and the cycle time and each cell status.
We will know which cell have problem if any abnormal things happen.
And also for the BMS system, there are overload and over discharge warming for the battery. And we can see the charging current and voltage and discharging current and voltage from the BMS system.

Which you can see the charging voltage and discharging voltage
8 units inside the cabinet.
And the 8units connect in series, and the cable is for communication, and show the data to the BMS system screen.

The BMS system will drive down overall costs, including those related to the warranty.

The lithium battery capacity is 380V 150Ah, capacity is
The lithium battery can supply the CT machine work for 1.2hrs if fully charge.

Because the medical bus only 10 meters, the space is very limited. If we put on the gel battery, it will need 32pcs 150Ah gel battery to work as 384V 150Ah capacity. It will need a large space for the gel battery.
But the medical bus is only 10 meters, it do not have enough space to put on all the gel batteries.

As for the lithium battery, we have special design to make it suit the medical bus. If you have requirement for the lithium battery, welcome to contact us

Gel battery cannot 100% discharge. But lithium battery can be 100% discharge.

Gel battery max discharge current is smaller than the lithium battery.
For the medical bus, it will require a very large discharge current from the battery to supply power to the CT machine.
That’s why we use the lithium battery than the gel battery
