<p>The invention relates to charge balancing of cells (3, 4) of rechargeable batteries (1, 2), such as that based on the electrochemical reaction between a negative electrode of a lithium-aluminium alloy and a positive electrode of iron sulphide. The battery (1, 2) has means to balance the charge in the cells of the battery comprising connection means (8) to enable distribution of hydrogen between all of the cells (3, 4) and means (9, 10) to remove the hydrogen from the cells (3, 4). As the battery (1, 2) is started up and hydrogen is formed from the reaction of water with the lithium, each cell (3, 4) will discharge to zero charge and thus they will all recharge from a common base point. The battery (1, 2) may further include means for maintaining the cells (3, 4) within the battery (1, 2) at a uniform state of charge by monitoring the charge on each cell (3, 4) to detect if the charge on a cell (3, 4) becomes out of balance with the other cells (3, 4) and adding hydrogen to the cells (3, 4) when the charges are detected to be out of balance to ensure that all the cells (3, 4) self-discharge.</p> |
