How is the lithium battery charge of forklift truck calculated? Details of the specification and parameters of forklift truck lithium batteries

As the main production supplier of power batteries in China, Shenzhen Mottcell New Energy Technology Co., Ltd., we will introduce some basic knowledge and Google parameters about the lithium battery of electric forklift trucks:

Electricity refers to the amount of electricity needed by electrical equipment, also known as electric energy or electric work. The unit of electric energy is kilowatt · hour (kW · h), also known as electric degree, W=P * t.

1. Electricity consumption (degree) of electrical appliances = the total amount of power used (W) * Electricity consumption time (H) / 1000.

2. Battery power (WH) = battery voltage (V) * Battery capacity (AH).

3. Battery power (WH) = battery voltage (V) * Battery capacity (mAH) / 1000.

9*0.8=7.2w=0.0072KW, consumes 0.0072 degrees per hour;

9*1=9w=0.009KW, consumes 0.009 degrees per hour.

Then, for 24 hours of total power consumption (0.0072 + 0.009) * 24=0.388 degrees.

Battery capacity is one of the important performance indicators to measure the performance of the battery. It indicates the power released under certain conditions (discharge rate, temperature, termination voltage, etc.) by the battery (available in JS-150D for discharge test), that is, the capacity of the battery, usually in ampere · hours (referred to, in A · H, 1A · h=3600C).

Battery capacity is divided into actual capacity, theoretical capacity and rated capacity according to different conditions. The calculation formula of battery capacity C is C= t0It1dt (integral of current I from t0 to t1), and the battery is divided into positive and negative electrodes.

Battery has complex electrochemical characteristics, such as open circuit voltage, load voltage, temperature, internal resistance, electrolyte specific gravity, electrolyte conductivity and other parameters, resulting in some basic detection methods, such as densitometric method, open circuit voltage method, discharge voltage method, measuring constant current voltage method, internal resistance method, according to their size, through the reference model calculation to predict the battery residual power.
