Abstract

The subject matter of the invention is a battery forming unit, working as a final element of a production line, where the batteries are electrochemically formed. The unit consisting of a base for placing assembled batteries and electric forming equipment, is characterized in that the base is a belt conveyor (3) located in a tank (1) with at least one declining wall (2), and a inflow (6) and outflow (8) system.

Description

Battery forming unit
The subject matter of the invention is a battery forming unit, working as a final element of a production line, where the batteries are electrochemically formed.
The existing solutions for battery forming in production lines have involved a base, where the loading terminals of a power installation were connected to the placed battery.
During electrochemical forming a significant amount of heat is produced, which adversely affects the forming process and the operating durability of the battery.
In order to decrease the influence of temperature on the forming process, the loading current is decreased, which extends the duration of the forming process.
The purpose of the invention is eliminating those inconveniences.
The essence of the invention, that is the battery forming unit consisting of a base for placing assembled batteries and electric forming equipment, lies in that the base is a belt conveyor located in a tank with at least one declining wall, and a inflow/outflow system. It is preferred that the liquid drain system is connected to a cooler.
It is also preferred that the tank is equipped with a liquid circulation system.
It is also preferred that the tank is equipped with a temperature sensor located in the referential battery area, connected with a flow controller.
It is also preferred that the tank is equipped with a liquid level indicator.
It is also preferred that the belt conveyor is equipped with a feed controller.
Use of the unit specified in the invention provides the following technical and functional effects of the invention:
- maintaining constant temperature of battery forming,
- stabilization of electrochemical processes during battery forming,
- decrease of battery forming duration,
- increase of operating durability of batteries,
- decrease of power required for battery forming.
The subject matter of the invention, in sample execution, is presented in the figure, which depicts schematically the tank with batteries and the water system.
The unit comprises of the tank 1, with declining front and rear walls 2. After the walls 2 are closed the tank comprises a tight container open at the top.
The tank 1 holds the conveyor 3, with the drive 4 connected to the feed controller E
The tank 1 is equipped with the cold water inflow system 6 with several inflow openings 7 and water outflow system 8 with several outflow openings 9 located in the tank 1 at the top water level and with the water drain outlet 10 in the tank bottom.
The cold water inflow system 6 is connected to the cooler !i, and the cooler inlet is connected to the outflow system 8.
The inflow system 6 is connected to the inflow controller 12, coupled with the temperature sensor 13 located within the area of the reference battery. The tank 1 is also equipped with a liquid circulation system 14 with a pump 15 connected at the upside with pipes 17 with holes at the top fill level 16 and at the downside with pipes 37 with holes in the bottom of the tank 1, as well as with the fill level indicator 19.
In order to form batteries 18 after they have been assembled, the batteries 18 are supplied with a belt conveyor, not shown in the figure, to the front wall 2 of the tank 1.
The wall 2 is opened and the batteries 18 are placed on the conveyor 3. After a row of batteries is placed the conveyor 3 moves by the distance required for placing another row of batteries 18 on the conveyor 3. After the batteries 18 are placed on the conveyor 3 filling the total working space, the wall 2 of the tank 1 is closed.
The electric terminals are connected to batteries 18, not shown in the figure. Each battery group placed in the tank has at least one reference battery 18, which is used for measurements of forming status.
To this battery the electrolyte temperature sensor 13 is connected. Then the tank 1 is filled with cold water and the forming process of batteries 18 is started.
The process is exothermic, in which the electrolyte temperature is raising, and with it the case temperature.
Water flowing around the case receives heat. In order to distribute heat evenly in the tank 1, the water circulation system 14 is activated, which draws water at the high level and supplies it to the tank bottom 1. If the temperature at the reference battery 18 exceeds maximum value, the cooling system is turned on. Some water is pumped away with the outflow system 8, and then cooled water is supplied with the inflow system 6. This process is repeated in cycles depending on the set limits of electrolyte temperature at the reference battery 18. After the forming process of batteries 18 is finished, the water is drained from the tank 1 through the outlet 10. The electric terminals of the loading system are removed from the batteries. Then the second wall 2 of the tank 1 is opened and the conveyor 3 moves in steps, receiving formed batteries 18 and placing them on the receiving conveyor not shown in the figure.
