As power battery for electric vehicle,lead acid battery has many shortcomings such as low specific capacity,the poor ability of charge acceptance and low active material utilization efficiency;corrosion of grid,sulfating of negative electrode ,hydrogen and oxygen evolution reaction and other phenomena occur during over charge-discharge and cause the capacity loss or fade to the batteries.

作为电动车用电池，铅酸蓄电池仍然存在着比能量低、充电接受能力差、活性物质利用率低等缺点，板栅的腐蚀、负极硫酸盐化、析氢、析氧等现象会引起充放电过程中不必要的副反应，这将导致电池容量的损失及衰减。

Avoid sulfation for ordinary batteries, if they are in an overcharging mode or undercharging mode for a longtime, it will make the battery lose its internal water and lead to sulfation, thus greatly shortening charger's operating lifetime. But can solve batteries' problem of imbalance derived from longtime overcharging and undercharging, thus avoiding internal sulfation of the battery, restoring batteries' capacity and extending their operating lifetime.

避免硫酸盐化--普通电池如果长期处在一种过充电或欠充电状态中，会使电池内部不断失水和硫酸盐化，这样就会大大缩短充电器使用寿命，可是，它能解决电池长期过充电和欠充电引起的失衡，避免电池内部硫酸盐化，能够恢复电池容量，从而延长它的使用寿命。

这可能是由于记忆不好的问题电池，或者您可能没有安装电池。

This article introduces the structure, principles and performance of several low-noise gear pumps, analyses that gear pump is the noise source in the new internal combustion forklift and battery forklift, provides some methods which can reduce the gear pump noise, and establishes the matching relation between gear modulus and pressure angle of the gear pump, which is applied to the new internal combustion forklift and forklift battery.

摘 要：本文介绍几种低噪声齿轮泵的结构、原理和性能，分析了新型内燃叉车和电瓶叉车中齿轮泵是噪声源，给出了可降低齿轮泵噪声的方法，建立了该种齿轮泵的齿轮摸数和压力角匹配关系，并在某新型内燃叉车和电瓶叉车上得到应用。

The charge control method is: input the battery module and the rectifier transformer to one of the first and second plug base; and using the first voltage detector and the second voltage detector to judge the input voltage of the first and second plug base, so to relatively control the conducting state of the first switch, the second switch, the third switch and the fourth switch, and so to make the rectifier transformer charge the battery module through the control of charge current in the charger.

该充电控制方法，是将电池模块及整流变压器分别输入第一及第二插座其中之一；并由第一及第二电压侦测器判断第一插座及第二插座的输入电压，以相对控制第一开关、第二开关、第三开关及第四开关的导通状态，使整流变压器可经由充电器的充电电流控制对电池模块进行充电。
