Manutenção de baterias de sódio inclui principalmente os seguintes aspectos:
Replacement of battery compartment and charger: Since sodium batteries differ from lead-acid batteries in energy density and volume, the original battery compartment may not be able to accommodate the new sodium battery, so it is necessary to replace a new battery compartment that is more suitable for the size and weight of the sodium battery. At the same time, since sodium batteries require a dedicated charger, the original charger suitable for As baterias de chumbo-ácido não podem atender às necessidades das baterias de sódio, portanto o carregador de veículos elétricos também precisa ser substituído .
Add protection board: In the process of replacing batteries, adding a sodium battery protection board is an indispensable part. Sodium batteries have more stringent requirements on current and charging status. The protection board can effectively prevent potential risks such as overcharging and over-discharging of the battery, thereby ensuring the safe operation of electric vehicles.
Battery Management System (BMS) Upgrade: BMS is responsible for managing charging and discharging, temperature, etc., and the parameters need to be reset to adapt to the characteristics of sodium batteries. In addition, temperature sensors also need to be added to prevent battery overheating and ensure safety.
Calibration of controller and instrument panel: Controller parameters need to be calibrated, undervoltage protection value, overcurrent protection threshold, etc. need to be reset. The power display algorithm of the instrument panel also needs to be recalibrated or a new instrument panel needs to be replaced to ensure the accuracy of the power display.
Ajustamento de outros sistemas de energia: incluindo calibração dos parâmetros do controlador, estabelecendo o valor de proteção de subtensão, limiar de proteção de sobrecorrente, etc ., para garantir a operação estável de todo o sistema de energia .
Através das medidas de manutenção acima, a vida útil da bateria de sódio pode ser efetivamente estendida e sua operação segura e eficiente pode ser garantida .
