Abstract
According to some embodiments, a battery management system for a metal-hydrogen battery system is presented. In particular, a method of managing a battery system includes applying a charging current through a battery string of the battery system, the battery string including a plurality of coupled batteries; monitoring temperature of the plurality of batteries; determining a maximum charging voltage from a Vtable that relate the charging current, the temperature, and the maximum charging voltage for each battery in the battery string; and stopping the charging current when a voltage across one or more of the batteries of the battery string reaches the maximum charging voltage.
Claims46
A method of managing a battery system, comprising:
- applying a charging current through a battery string of the battery system, the battery string including a plurality of coupled batteries;
- monitoring temperature of the plurality of batteries;
- determining a maximum charging voltage from a Vtable that relate the charging current, the temperature, and the maximum charging voltage for each battery in the battery string;
- and
- stopping the charging current when a voltage across one or more of the batteries of the battery string reaches the maximum charging voltage.
A battery management system (BMS), the BMS comprising:
- a battery interface configured to communicate with battery monitors, the battery monitors configured to monitor parameters of a plurality of batteries, the plurality of batteries being coupled to form a battery string;
- a terminal interface, the configured to communicate with terminal electronics, the terminal electronics configured to control current and voltage of the battery string in accordance with control signals received from the terminal interface;
- a memory, the memory configured to hold instructions and data;
- and
- a processor coupled to the memory, the terminal interface, and the battery interface, wherein the processor executes instructions stored in the memory to
- provide control signals to the terminal interface to direct the terminal electronics to apply a charging current through the battery string, the battery string including a plurality of coupled batteries;
- monitor temperature of the plurality of batteries through the battery interface;
- determine a maximum charging voltage from a Vtable that relate the charging current, the temperature, and the maximum charging voltage for each of the plurality of batteries;
- provide control signals to the terminal interface to stop the charging current when a voltage across one or more of the plurality of batteries in the battery string reaches the maximum charging voltage.
