Basic parameters of power battery
Power battery is an important part of electric vehicle, it stores and releases electrical energy for electric vehicle
Provide driving force. The basic parameters of the power battery are described in detail below.
1. Capacity
Capacity refers to the ability of a power battery to store electrical energy, usually in ampere-hours (Ah). Volumetric overload
The more energy the battery stores, the farther the electric vehicle can travel. Power battery capacity
It is related to electric vehicle models and use needs. Generally speaking, the capacity of electric vehicles is between 10 and 100Ah.
2. Voltage
Voltage refers to the potential difference between the positive and negative terminals of a power battery, usually in volts (V). voltage
Determines the size of electric energy, but also directly affects the performance of electric vehicles. Power batteries common to electricity
The voltage is 12V, 48V, 72V and 96V.
3. Rechargeability
The power battery can be recharged and discharged repeatedly, which is called rechargeability. Good power batteries should have
High rechargeable performance, able to charge and discharge multiple times without affecting battery life. Rechargeability can be passed
cycle life (cycle life) is measured, that is, how many times the battery can be charged and discharged.
4. Self-discharge Rate
Self-discharge rate refers to the power battery in the static state, the power loss per unit time
Rate. A good power battery should have a low self-discharge rate, so that the battery is not used for a long time
Can maintain high electrical energy.
5. Energy Density
Energy density is the amount of electrical energy stored per unit volume or weight. Power battery energy
The higher the density, the more electrical energy is stored, and the longer the range of the electric vehicle will be. Currently, lithium ions
Batteries have a big advantage in terms of energy density.
6. Power Density
Power density refers to the rate at which a power battery can release electricity per unit volume or per unit weight.
The higher the power density, the stronger the output capacity of the battery, and the better the acceleration performance of the electric vehicle. And energy
The difference in density is that power density pays more attention to the transient performance of the battery.
