蓄电池

This paper presents mainly the reconstruction of controlling system from the single-driver room to the dual-driver rooms based on explosion-proof special chopping regulating speed battery locomotive according to requirement of safe transporting and producing in coal mine.

根据煤矿井下运输安全生产的需要，对防爆特殊型蓄电池式斩波调速电机车进行改造，由单司机室控制改成双司机室控制。

Our scientific research, production of scientific research, production and distribution, service as one of professional battery enterprise.

我公司集科研，生产集科研，生产流通，服务为一体的专业性蓄电池企业。

When out of service for a long period.the battery should be stored in a dry and cold place.

当长期不使用时，蓄电池要储放在干燥阴凉之处。

Shorten the service life of the zinc-silver battery was shortened.

使锌银蓄电池的使用寿命缩短。

"Battery Service and Maintenance can be divided into four parts : testing, repair, charging, and care of Batteries in the stock."

蓄电池的维修可以分为四部分：检查、修理、充电和保养。

20 The battery charger should be self-ventilated and be suitable for operating continuously.

6.3.3.20 蓄电池充电器最好为用于连续运行的自通风型。

Further, this type has a modestly lower self discharge rate of 1-3% versus up to 15% with standard lead-acid batteries.

此外，这种类型有一个温和走低自我放电率的1-3 ％，高达15 ％，与标准式铅酸蓄电池。

Finally, the simulation of the system and the experimental results of PWM rectifier are presented. The results of the simulation and experiment indicate that the input power factor is close to 1, the output voltage of the rectifier is stable and the high quality charge and discharge: current of the accumulator is achieved, current ripple is small.

本文最后给出了系统的仿真和PWM整流器实验波形，仿真和实验的结果表明：系统实现了输入功率因数接近1，变流器输出电压稳定；获得了较高质量的蓄电池充放电电流，电流纹波小。

The company may try to make it more appealing by including a normal battery and putting an appropriate price tag that would make up for the low display quality.

该公司可尝试使其更具吸引力，包括正常的蓄电池，把适当的代价这将弥补低品质展示。

How long will it take to charge up the batter?

给这个蓄电池充电要用多少时间？
