■ What Is ZuBat Diagnostic Service?

ZuBat Diagnostic Service delivers instant degradation diagnostics for lithium‑ion batteries.

This eliminates the previously required specialized equipment, expert knowledge, and lengthy measurements.

With a simple connect‑and‑press operation, anyone can accurately check a battery’s health.

■ Key Features

1. High-Speed Diagnosis

Results are output in approximately 1 second*, enabling on‑the‑spot verification of battery health.

* Measurement time for the battery state only; time to display results is excluded.

2. Easy Operation

No prior or specialized knowledge required—anyone can measure.

The interface is intuitive, with no complicated steps.

3. Customizable

We provide customized battery diagnostic equipment built to customer specifications.

This enables implementation for in‑process inspections in operational workflows, including production lines.

★The service can be launched in as little as 1 month.

Flow to Obtain Lithium‑Ion Battery Characteristic Data:

We borrow 3 sample batteries*

* We will borrow 3 sample batteries for diagnosis, as available from the client.

1. New unit　2. Used unit (approx. 1 year in service)　3. Degraded unit (approx. 2 years in service)

4. Cloud‑Based Data Management

Cloud‑based centralized management of measurement data enables long‑term analysis of degradation trends.

Diagnostic results support CSV export, allowing smooth integration with existing systems.

■ Why Battery Diagnosis Matters

◎Prevent Failures and Ensure Safety

・Avoid unexpected failures

By assessing the state of battery degradation, the replacement timing can be predicted before issues such as charging failures or power loss occur.

・Degradation from self‑discharge

Lithium‑ion batteries risk going into a deep‑discharged “sleep” state and becoming non‑rechargeable if not stored at an appropriate state of charge (typically 30–50%). Diagnosis checks for damage caused by long‑term storage.

・Reduce risks of overheating and ignition

Especially with lithium‑ion batteries, abnormalities such as internal short circuits increase the risk of overheating or ignition.

Diagnosis helps detect latent issues early to prevent major accidents.

◎Maintain Performance and Maximize Service Life

・Visualize battery health

Battery degradation can be determined instantly and accurately using a device that measures battery condition.

* SOC (State of Charge): Indicates remaining charge.

➡100% when full and 0% when empty; this indicates how much charge remains.

➡Not measured by ZuBat Diagnosis.

※SOH (State of Health): Indicates battery health (service life).

➡100% when new; this will decrease to 80%, 70%, etc. as it ages.

➡Measured by ZuBat Diagnosis.

・Determine appropriate usage

Based on the diagnostic results, measures to extend battery life can be implemented, such as revising charging frequency and operating conditions.

◎Reduce Costs

・Avoid unnecessary replacements

Battery diagnostics prevent the replacement of batteries that are still usable, helping reduce unnecessary costs.

・Lower repair costs with early intervention

Detecting and addressing minor issues early prevents costly major repairs or full equipment replacement later.
