Now electric vehicles have become a trend, but it is especially important to choose the battery of an electric car. Today I will tell you about this piece.
1 battery type has primary battery, secondary battery, or storage system;
2 electrochemical system advantages, shortcomings and battery characteristics match the main requirements of the equipment;
3 voltage nominal or working voltage, maximum and minimum allowable voltage, voltage regulation, discharge curve, start-up time, voltage hysteresis;
4 load current and load curve constant current, constant resistance, constant power or other, load current or single value load, variable load, pulse load;
3 cycle work system continuous or intermittent, if you need to adopt a cyclic work system;
6 temperature requirements required operating temperature range;
7 working hours required for service life;
8 physical requirements size, shape, quality, extreme;
9 storage life activation / storage battery system, the charge during storage, storage time varies with temperature, humidity and other conditions;
10 charge and discharge cycle (rechargeable battery) float charging or recycling, the required number of cycles, the practicality and characteristics of the charging power supply, charging efficiency;
11 environmental conditions vibration, impact, centrifugal rotation, acceleration, etc., atmospheric conditions (pressure, humidity, etc.);
12 safety and reliability allowable rate of change, failure rate, no degassing or no leakage, using potentially toxic and hazardous substances, exhaust gas or liquid type, high temperature, etc., working under severe and potentially dangerous conditions, environment friendly.
