Battery electrolyte level control system
First Claim
1. An electrolyte level control system for adding a fluid to an electrolyte within a battery chamber defined by a battery carried by an electric vehicle, comprising:
- a reservoir configured to contain a quantity of the fluid;
a battery-charge sensor configured to sense the state of charge of the battery; and
a battery-refill control system configured to control the distribution of the fluid from the reservoir to the battery chamber based upon the state of charge sensed by the battery-charge sensor.

Abstract
An electrolyte level control system for adding a quantity of water to raise the electrolyte level in a forklift battery having a hydro-mechanical cutoff valve. The system includes a reservoir, a reservoir-level sensor, a transmitter, a distribution system, a battery-charge sensor, a solenoid valve, a battery electrolyte level sensor, and a battery-electrolyte control system that controls the position of the solenoid valve in light of the detection of a battery state of charge from the battery charge sensor, and the detection of the battery electrolyte level from the battery electrolyte level sensor. The system provides for watering the battery when the state of charge is full and the electrolyte level is not full.
