Battery

One or multiple battery clusters can be bound to the same EMS.

Device List

Tapping Battery, you'll see all battery clusters under the EMS and the basic information about each battery cluster.

Device Details

Tap a battery cluster to go to its details page.

Here is a description of the battery details page:

Serial Number	Name	Description
a	Basic device information	Displays the device model, device SN, device status and running status.
b	Data refresh setting	You can view the last data refresh time and set the refresh interval for the page. Three options: 1 minute, 3 minutes, and 5 minutes.
c	Detailed device information	Displays： Battery SOC: The percentage of the remaining battery energy to the total battery capacity. Battery SOH: Used to measure the health of the battery. Battery Cluster Current: It helps users judge whether the battery cluster is operating normally by monitoring the current of the battery cluster. Battery Cluster Voltage: It helps users judge whether the battery cluster is operating normally by monitoring the voltage of the battery cluster. Total Charge: The sum of the power the battery cluster takes from the outside. Total Discharge: The sum of the power the battery cluster releases to the outside. Maximum Cell Voltage: The largest voltage of cells. Minimum Cell Voltage: The smallest voltage of cells. Maximum Cell Temperature: The largest temperature of cells. Minimum Cell Temperature: The smallest temperature of cells. Insulation Resistance: Insulation resistance is the resistance between the battery housing and the electrical components inside. It can be used to evaluate the safety and stability of the battery. Cycle Time: A cycle refers to the battery goes from fully charged to fully discharged and to fully charged again. When the number of cycles exceeds a certain range, the capacity and performance of the battery will decrease significantly.
d	Icon	When you tap this icon, a drop-down menu will appear. You can select “Pack” or “Cells” to enter its detail page.

[!NOTE] Cell is the basic unit of the battery but also is the core component of the battery. Monitoring the voltage and temperature of the cell helps you learn about the operating status of the battery and find and solve problems in time.

Device Maintenance

At the battery list, select a battery and tap Maintain, to go to the Maintain page.

At the Maintain page, you can:

• view the device status, device model, device SN, firmware version, hardware version, and online time.
• upgrade the firmware.
