DEVICE FOR INJECTING LIQUID ELECTROLYTE INTO BATTERY

摘要

A device for injecting a liquid electrolyte into a battery addresses a problem that the injection amount of the liquid electrolyte becomes excessive because the liquid electrolyte volatizes at injection if remaining in a chamber. The device has a liquid injecting pump for injecting the liquid electrolyte into the battery positioned inside the chamber which has been sealed in a depressurized state and a vacuum pump for depressurizing the inside of the chamber. A vacuum attainment time until a pressure of the inside of the chamber becomes in a predetermined vacuum state is measured, and if this vacuum attainment time becomes longer than a predetermined value, the injection amount of the liquid electrolyte is corrected downwards.

1. A device for injecting a liquid electrolyte into a battery, comprising:
a liquid injecting pump for injecting the liquid electrolyte into the battery positioned inside a chamber which has been sealed in a depressurized state; a vacuum pump for depressurizing the inside of the chamber; a vacuum attainment time measuring unit for measuring a vacuum attainment time until a pressure of the inside of the chamber becomes in a predetermined vacuum state by the vacuum pump; and an injection amount correcting unit for correcting an injection amount of the liquid electrolyte according to the vacuum attainment time.
