How to charge a sodium-ion battery

Charge a sodium-ion battery only with a charger or inverter approved for that exact battery system.

By The Sodium Battery Guide team · Updated 10 November 2026

What matters

The charger raises cell voltage under controlled current, then limits voltage as the pack fills. The BMS watches cell voltages, temperatures and current, balances cells and opens contactors if limits are exceeded.

The detail

Different sodium cathodes and anodes use different voltage windows. A “48 V” label is a system class, not a complete charge specification. Low-temperature capability also belongs to the particular pack.

Practical conclusion

Do not change installer settings to chase capacity. Use approved firmware, preserve communications between battery and inverter, and investigate repeated alarms.
