Technical Diagnosis
Review voltage, charging behavior, storage time, application route, installation status, BMS or protection signals and usage records to identify likely causes.
After-sales system
Battery problems rarely happen in a laboratory. They happen on delivery routes, in vehicles, inside backup systems and at customer sites where downtime costs money. NaVolt helps partners diagnose issues quickly, separate product risk from usage or system mismatch, and keep end users confident in the battery program.

Service coverage
Review voltage, charging behavior, storage time, application route, installation status, BMS or protection signals and usage records to identify likely causes.
Collect model, batch information, purchase records, photos, videos, test data and operating feedback so each case can be reviewed with traceable information.
Coordinate replacement planning, shipment communication and partner response when a confirmed product or delivery issue requires corrective action.
Provide practical notes for charging, storage, maintenance, low-temperature operation, vehicle matching and safety across sodium-ion battery and PACK applications.
Case preparation
The more complete the first report is, the faster our technical team can judge whether the issue comes from the battery, charger, controller, inverter, installation, storage or operating conditions.
Product model, voltage, capacity, batch number and purchase record
Application scenario, vehicle or equipment model, charger or system setting and operating environment
Clear photos or videos of the battery, wiring, label, fault indicator and installation position
Measured voltage, current, temperature, protection signal, error code and recent usage history when available
Response workflow
01
Collect product information, application scenario, issue description, photos, videos and test data.
02
Service and engineering teams review battery status, system matching, charging behavior, storage history and operating conditions.
03
Confirm repair advice, usage correction, replacement plan, warranty handling or further test requirements.
04
Track the case result, summarize the cause and provide prevention advice for future batches or projects.
Risk prevention
After-sales service is not only about solving failures. NaVolt helps partners reduce repeated problems by improving matching habits, storage control, installation details and customer usage education.
Review vehicle compatibility, terminal layout, CCA demand, cold-route use, charging behavior and replacement guidance before broad market launch.
Check high-pulse starting duty, storage duration, installation condition, vibration exposure and fleet feedback to reduce repeat service pressure.
Review BMS settings, load profile, connector condition, enclosure protection, thermal environment and charge-discharge strategy for long-term stability.
Send the model, batch information, application, issue description and supporting photos or videos. NaVolt will review the case with the appropriate technical contact.
