But we are more concerned about battery power, which is the new energy vehicles in the energy source.Currently the most common battery nickel hydrogen batteries, lead-acid batteries, and lithium batteries, nickel-metal hydride batteries currently phased out, lead-acid batteries ownership depends on the support, the current lithium battery as the mainstream market
Refers to the ratio of the energy per unit mass can output power of the battery, the unit is WH / kg
Specific power density is the ability to describe a battery can emit energy in an instant, the unit is w / kg
Like the tortoise in the tortoise and the hare, endurance is better than high energy battery, can work long hours, mileage long, but higher than the power in the battery meter race as Bolt, fast, can provide high instantaneous battery,
in order to ensure the car's acceleration performance. Fish and bear's paw can not have both, usually to a battery can not simultaneously have high specific energy and high specific power!
Installed in the car battery as a power source of energy, certainly more than we usually use a battery life of greater stability requirements. High temperature, low cold, high impact, etc. are likely to occur,
so as a battery, an indicator of stability is also essential!
