RoboCupJunior Japan Open 2017 Gifu/Nakatsugawa

Handling of Lithium-based Rechargeable Batteries
Batteries and Robots
Every lithium-based rechargeable battery (all lithium materials such as lithium ion) has to meetrequirements as follows:

1. Each battery must be labeled stating the manufacturer's product name, voltage,and so on. Additionally, participants must bring one of a product manual,specification or warranty card along with the battery.
Only batteries which are clearly stated the location of responsibility will be allowed to use at thevenue.

2. Participants are never allowed to use a battery cell and self-made or remodeled
battery. Also, don't use batteries with large scratches or deformed.
Handling of lithium-based rechargeable batteries is very delicate. Wounded or deformed battery
may have some trouble inside. Be sure to check this not only at the inspection but also before
starting the game or before charging.

3. The Capacitance of the lithium-based rechargeable battery is 45Wh or less (23Whor less for Soccer LightWeight league). Also, parallel/serial use of rechargeable
batteries is prohibited.
Other leagues for the soccer have no regulation on the capacitance, though, it is encouraged tokeep less than 45Wh as the common standard for all league. Also, It 's hard to keep a balance
between cells of lithium-based rechargeable batteries, so it is prohibited to connect plural
batteries in parallel or in series.

4. Every robot and a lithium-based rechargeable battery should have theovercurrent/over-discharging protection. Or the team needs to have an own
procedure for safety use of the battery. Team members are required to explain
about its measures of safety by showing the outline with diagrams.
--

If the rechargeable battery has an internal protection circuit, please describe it's detailed. If
not, participants have to add the overcurrent, over-discharging, and overheat protection
externally. Same as this, if a team cannot describe the operation of the built-in protection,
the team must add protection circuits on the outside.
Each robot putting lithium-based rechargeable batteries needs to install an overcurrent
protection circuit or a fuse of 20A or less in the vicinity of the rechargeable battery as a shortcircuit.

5. The rechargeable battery mounted on the robot must be fixed and protected sothat it will not be damaged during the game.

Charger
The charger used at the venue needs to satisfy the following criteria.

6. The charger must be a PSE certified product*.
Chargers without authentication are not allowed using at the venue. DC type charger is notallowed because it has no authentication.

7. The charger has to be satisfied the specification for charging batteries that teamuses. Teams are encouraged to use a charger which is designated from orrecommended by a rechargeable battery manufacturer. A team should bring a
document for clarification to the venue.

8. If the charger is not designated from or recommended by a manufacturer, thecharge rate is limited up to 1C or less.
9. Teams can charge within the paddock during the event. While charging, the teamhas to display a sign of 'Charging' so that the other participants can recognize it,
and at least one member of the team needs to monitor charging for not missing adangerous sign.
Batteries and chargers that do not conform to the above criteria cannot be brought into the venue.
There will be held a special battery inspection separately from regular robot inspection. Please bring
the necessary documents to the venue and get the battery inspection.
Teams need to submit a set of "The Lithium rechargeable battery usage application form" for eachrobot that uses a lithium-based rechargeable battery. If a team uses plural kinds of lithium-based
rechargeable batteries for one robot, please prepare a describe document for each battery.

*Attention:
Dear a team mentor and the father/mother/guardian of each team member,
Please confirm every description of a battery and the protection circuit or a procedure for safety
usage. If you could agree with team's description in the documents, please sign your signature on theapplication form. We need a set of the application form before the competition day for grasping a
number of the team that uses lithium-based chargeable batteries in advance. It would help us if youcould send a copy of these documents via email (mailto:gifu.nakatsugawa.battery@gmail.com) assoon as possible, before your departure to Japan at the latest.

*Further information about PSE and the Electrical Appliance and Material Safety Law, please refer alink as follow:
