**New Energy Car Battery Technology**
In recent years, with the rapid growth of new energy vehicle production and sales, China's power battery industry has made significant progress. The power battery is the core component of a new energy vehicle, serving as the energy source that directly determines the vehicle’s range and performance.
The Chinese power battery market is dominated by local companies, with a clear stratified structure. According to technical level and market performance, it can be divided into four tiers. Leading enterprises like BYD and CATL are at the top, leveraging their technological edge and scale advantages to achieve significant cost reductions. They hold a dominant position in the market.
Currently, ternary lithium batteries are primarily used in passenger cars, while lithium iron phosphate batteries are more common in commercial vehicles. These two types dominate the industry due to their balance of performance and cost.
**Classification of New Energy Batteries**
**1. Lead-Acid Battery**
Although relatively mature, lead-acid batteries remain the only mass-produced option for electric vehicles due to their low cost and high discharge rate. They were even used during the Beijing Olympics for transportation services. However, they suffer from low specific energy, power, and energy density, limiting the speed and range of electric vehicles.
**2. Nickel-Cadmium and Nickel-Metal Hydride (Ni-MH) Batteries**
These batteries offer better performance than lead-acid but contain toxic heavy metals, posing environmental risks when disposed of. Ni-MH batteries have been widely used in hybrid vehicles, with Toyota’s Prius being a well-known example. Most hybrid models globally use Ni-MH technology, though domestic development in China is still in the early stages.
**3. Lithium-Ion Batteries**
Lithium-ion batteries are increasingly preferred for their high voltage, large specific energy, lightweight design, long cycle life, and no memory effect. Major automakers like Ford, Toyota, and BYD are investing heavily in this technology. However, challenges remain, especially regarding safety and charge management. Improper charging and discharging can lead to performance degradation or failure.
**4. Lithium Iron Phosphate (LiFePOâ‚„) Battery**
This type of lithium battery offers high safety, long cycle life, and lower cost. It is becoming a popular choice for vehicle power systems. BYD’s “iron battery†is believed to be based on this technology.
**5. Fuel Cell**
Fuel cells generate electricity by converting chemical energy from fuel and an oxidant. Proton exchange membrane fuel cells are particularly promising for automotive use. They operate efficiently without combustion, offering higher energy conversion rates compared to traditional power sources.
**Breakthroughs in Power Battery Technology**
China’s power battery industry has seen substantial progress, with energy density reaching 150 Wh/kg. By 2020, the goal was to exceed 300 Wh/kg for individual battery units. Companies like CATL and Lishen have achieved significant breakthroughs, improving both energy density and safety.
Solid-state batteries are emerging as a game-changer, with higher energy density and improved safety. Fisker Motors recently introduced a solid-state battery capable of 804 km range with just one minute of charging. While challenges like low conductivity remain, if commercialized at scale, solid-state batteries could revolutionize the EV market.
**Future Outlook**
Experts predict that by 2025, the range of affordable electric vehicles will reach 300-400 km, and by 2030, solid-state batteries could push ranges beyond 500 km. With continued innovation and reduced costs, electric vehicles are on track to surpass traditional gasoline-powered cars in efficiency and practicality.
Programmable DC Power Supplies
The CSP series Programmable DC Power Supply is upgraded and developed on the basis of iDealTek-Electronics' mature IGBT high frequency switching power topology and all-digital signal control loop. Featured with high precision, low ripple and fast response speed.
The Programmable DC Power Supply is different from the traditional DC power supply that can only control the output voltage and current values. The programmable DC Power Supplies can realize the programming of multiple parameters through adding the microprocessor unit with built-in control program, such as parameters like operating time, output rise time, protection response time, OVP and OCP etc. All can be set and programmed.
At the same time, the microprocessor unit also adds more functions to the power monitoring system, which can realize the query of the historical data of the test results, making the programmable DC power supply the best choice for laboratory test, production line manufacturing test, photovoltaic plate aging test and various cutting-edge applications with Programmable DC power supplies.
This series of Programmable Power Supplies have a total of 4 standard rated power levels, ranging from 1KW Desktop Programmable Laboratory power supplies to 3KW / 6KW / 10KW Rack-mounted Programmable DC power supplies. The maximum output voltage ranges from 600V to 1000V under different rated powers.
Beautiful appearance design with small and compact size, the whole series power supplies adopt silicone buttons, stepless knobs and LCD display on control panel layout. The output voltage, current, start / stop time, output rising rate, OVP, OCP and other parameter setting programming and reading of the Programmable Power Supplies can be easily and quickly completed through the front panel man-machine interface, up to 5 digits of high-precision programming and monitoring levels make the measurement results of the programmable DC power supply accurate and reliable, almost no need to use external power meters.
At the same time, the whole series of programmable DC power supplies are equipped with RS485 interface as standard, following the MODBUS-RTU international protocol, which can realize remote control programming, test results save and uploading to the master unit and status monitoring of the power supply.
