Troubleshooting of KPX electric vehicle battery

Many reasons for battery failure, besides the manufacturing quality andtransportation and storage of things, most is due to improper maintenancecaused by. Find fault and analysis of reasons, to take effective measures as soon as possible to exclude. The following method of characteristic, batterymaintenance and common fault causes the:

The 1 polar plate irreversible sulfation

The 1.1 characteristic:

Battery capacity decrease;

The electrolyte density is lower than the normal value;

Start charging and charging is completed when the battery terminal voltage too high;

When charging the early occurrence of bubbles or bubble began chargingoccurs;

When the battery electrolyte temperature rise faster.

1.2 reasons

Initial charge deficiency;

Has been discharged or semi discharge state is placed for a long time;

The long-term insufficient charge;

Often excessive discharge;

Electrolyte density exceeds the specified value;

Electrolyte level is too low, resulting in the upper plate exposed surface;

Equalizing charge failed to timely;

The discharge current is too large or too small;

Electrolyte impurities;

Internal short circuit, local action or leakage.

1.3 remedial and preventive measures

The light by using the method of equalization charging processing;

In serious cases by "water therapy";

Can not discharge;

The density of the electrolyte can not exceed the specified value;

Electrolyte fluid level and impurity content should be in the specified range.

The battery internal short circuit
