Description
Claims (3)
- 電池パックに収納された電池を充電する充電装置であって、
電池パックを冷却する冷却手段と、
前記電池を所定電流で充電し、充電中に前記電池の電池温度勾配を検出する電池温度勾配検出手段と、
前記電池温度勾配検出手段が所定の温度勾配を超えたか否かを判定し、超えないときには前記所定電流で充電を継続し、満充電を検出したら充電を停止すると共に、
前記電池温度勾配が所定の温度勾配以上と判定したときには、前記電池の充電電流を前記所定電流より小さくして充電し、満充電を検出したら充電を停止する制御手段と、
を備えることを特徴とする充電装置。 - 請求項1において、前記制御手段は、前記電池温度勾配検出手段の出力信号より、前記冷却手段の冷却効果を判定し、前記冷却手段の冷却効果が小さいと判断したときには、冷却効果が正常と判断したときよりも充電電流を小さくすることを特徴とする充電装置。
- 請求項1において、電池の定格容量を検出する定格容量検出手段を備え、前記制御手段は、前記電池温度勾配が所定の温度勾配以上の場合、前記定格容量検出手段で検出された定格容量が大容量であるときには、検出された定格容量が小容量であるときよりも充電電流を小さくすることを特徴とする充電装置。
