Power-Eater

This is Ni-MH battery charger for mini4wd.

very low noise and low ripple
dv charge / discharge
cccvdv charge (i thinked new method for mini4wd charger)
- race charge method
- low internal resigtance, high voltage, many capacity
- low life
programable charge/discharge sequence
- can use battery tester
- complex sequence like IF

ミニ四駆用ニッケル水素充電器です。

ノイズやリプルが少ない
dv充電や放電ができる
cccvdv充電ができる
- レース用途に適している
- dv方式に比べて、低内部抵抗、高電圧、大容量の充電が可能
- 寿命は短くなる
充放電シーケンスを組むことができる
- 簡易充放電試験機として使用可能
- プログラムのIF文のような分岐も可能

Questions

How big is the Charge PCB?

It measures 132.8 × 93 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Charge use?

140 parts, built around the R5F21256SNFP#V2, ADM3202ARNZ, NJM2119M and MCP4922-E/P. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Charge KiCad files?

From the yu65536/Power-Eater repository on GitHub, at the commit this page was made from: the board is hardware/charge.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Charge design in my own project?

Its repository states no licence, so its author keeps all rights: ask yu65536 before reusing the design.
