Abstract
A liquid electrolyte battery (10) comprises a number of electrolytic cells (12), an inlet port (22) extending into a first electrolytic cell (12-1), an electrolyte transport channel (30) residing within each electrolytic cell, a number of carry-over passages (40) hydraulically connecting adjacent electrolytic cells, an outlet port (50) extending from a last electrolytic cell (12-4), and a pump (58) for introducing an electrolyte solution or air into the electrolytic cells. The battery electrolyte is replenished by introducing an electrolyte solution (14) into the first electrolytic cell, causing the electrolyte level to rise and be hydraulically transported through the carry-over passages to fill each electrolytic cell. The electrolyte exiting the last electrolytic cell is collected and reintroduced back into the first electrolytic cell and circulated throughout the battery. The electrolyte exiting the battery may be collected in an electrolyte reservoir (72) and circulated through a temperature management device (78) to ensure a battery temperature within design parameters. The electrolyte level in each electrolytic cell is adjusted to a predetermined level by introducing air into…
