Description

本発明は、蓄電池装置に係り、特に異なる充電条件の蓄電池を交換して使用される蓄電池充電方法に好適に利用できるものである。 The present invention relates to a storage battery device, and can be suitably used particularly for a storage battery charging method used by replacing storage batteries with different charging conditions.

従来の蓄電池を利用した車両(ゴルフカート、フォークリフト)の充電方法は電池電圧、充電電流、電池の周辺温度の検出と充電時間計測を行い、充電する電池に最適な定電流充電、定電圧充電を組み合わせて、充電終了および電池の充電不良等の条件判断を主にマイコンにて制御している。(例えば、特許文献1参照。)
特開2001−35540号公報(図1、図3)
The conventional charging method for vehicles (golf carts, forklifts) using storage batteries is to detect the battery voltage, charging current, battery ambient temperature and measure the charging time. In combination, conditions such as charge termination and battery charge failure are controlled mainly by a microcomputer. (For example, refer to Patent Document 1.)
JP 2001-35540 A (FIGS. 1 and 3)

しかしながら、前記従来車両に組み込まれた充電器の構成では、異なる充電条件の蓄電池への変更(たとえば、特許文献1 図2の充電方式フローチャートにより説明すると、開放型鉛蓄電池では、図3のブロック図にある、温度センサが装着されておらず、よって、充電電流の切り替え電圧は、固定したおのおののステップで指定された電圧値で充電電流切り替えいるが、密閉型鉛蓄電池の場合には、図3のブロック図にある、温度センサにより、電池温度を検出して、充電電流の切り替え電圧を6セル公称12V電池の場合、Vs=14.4+0.03(25−T)の計算式より算出して充電電流を切り替え、また、充電電流もより細かく設定し、最少充電電流で一定時間充電して充電を終了する際の時間設定も、第1、第2ステップでの充電時間と電池温度により設定される充電時間により細かく時間設定を行い、電池の充放電サイクル寿命を延ばす様になっている。)このような充電制御のための最適な充電手順をマイコンのプログラムとして新たに書き換えるか、電池の最適な充電手順をあらかじめマイコンのROMにメモリされているプログラムを選択するため、充電器のケースを開けて、制御基板ジャンパー設定を変更するなど、煩雑な手順を必要とするという課題を有していた。
本発明は、前記従来の課題を解決するもので、あらかじめ使用される異なる蓄電池の最適充電手順のプログラムを充電制御マイコンにメモリして、充電制御操作手段や表示手段で使用される蓄電池の充電プログラムを選択、設定を可能とした蓄電池充電装置を提供することを目的とする。
However, in the configuration of the charger incorporated in the conventional vehicle, a change to a storage battery with a different charging condition (for example, referring to the charging method flowchart of FIG. In the case of a sealed lead-acid battery, the charging current switching voltage is switched at the voltage value specified in each fixed step. The battery temperature is detected by the temperature sensor in the block diagram, and the charging voltage switching voltage is calculated from the formula Vs = 14.4 + 0.03 (25-T) in the case of a 6-cell nominal 12V battery. The charging current is switched, the charging current is set more finely, the time setting when charging is completed for a certain time with the minimum charging current and charging is completed in the first and second steps. The time is set finely according to the charging time set by the time and the battery temperature, and the charge / discharge cycle life of the battery is extended.) The optimum charging procedure for such charging control is newly added as a microcomputer program. In order to select the program stored in the microcomputer ROM in advance, or to change the control board jumper settings, the complicated procedure is required. It had the problem that.
The present invention solves the above-mentioned conventional problems, stores a program for optimal charging procedures for different storage batteries used in advance in a charge control microcomputer, and stores the charging program for the storage batteries used in charging control operation means and display means An object of the present invention is to provide a storage battery charger capable of selecting and setting a battery.

前記従来の課題を解決するために、本発明の蓄電池充電装置は、充電条件の異なる蓄電池(例えば開放型鉛蓄電池と密閉型鉛蓄電池)の充電を行うための複数の充電制御プログラムと、充電状態の操作手段を、前記異なる蓄電池の充電制御プログラムを選択する手段と兼用することを特徴としたものである。
また、本発明は、前記充電状態の表示手段で、選択された蓄電池の充電制御プログラムを表示できることを特徴としたものである。
さらに、蓄電池充電装置において、充電状態の表示手段で、選択された蓄電池の充電制御プログラムを表示できることを特徴としたものである。
In order to solve the conventional problems, a storage battery charging device according to the present invention includes a plurality of charge control programs for charging storage batteries having different charging conditions (for example, an open type lead storage battery and a sealed lead storage battery), and a charge state This operation means is also used as means for selecting the charge control program for the different storage battery.
In addition, the present invention is characterized in that a charging control program for a selected storage battery can be displayed by the charging state display means.
Furthermore, in the storage battery charging device, the charging control program of the selected storage battery can be displayed by the charging state display means.

本発明の蓄電池充電装置によれば、充電方法の異なる蓄電池を交換しても、最適な充電制御プログラムを選択、設定が容易に出来ることにより、鉛蓄電池以外のNiCd電池、NiH電池、リチウム電池に併用使用する際にも容易となる。   According to the storage battery charging device of the present invention, it is possible to easily select and set an optimal charge control program even if the storage batteries having different charging methods are replaced, so that NiCd batteries, NiH batteries, and lithium batteries other than lead storage batteries can be used.
